-NVIDIA Tegra114 pinmux controller
-
-The Tegra114 pinctrl binding is very similar to the Tegra20 and Tegra30
-pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
-nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
-a baseline, and only documents the differences between the two bindings.
-
-Required properties:
-- compatible: "nvidia,tegra114-pinmux"
-- reg: Should contain the register physical address and length for each of
-  the pad control and mux registers. The first bank of address must be the
-  driver strength pad control register address and second bank address must
-  be pinmux register address.
-
-Tegra114 adds the following optional properties for pin configuration subnodes:
-- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
-- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
-    until reset. 0: no, 1: yes.
-- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
-- nvidia,rcv-sel: Integer. Select VIL/VIH receivers. 0: normal, 1: high.
-- nvidia,drive-type: Integer. Valid range 0...3.
-
-As with Tegra20 and Terga30, see the Tegra TRM for complete details regarding
-which groups support which functionality.
-
-Valid values for pin and group names are:
-
-  per-pin mux groups:
-
-    These all support nvidia,function, nvidia,tristate, nvidia,pull,
-    nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
-    nvidia,io-reset and nvidia,rcv-sel.

+    Please refer to pinctrl-bindings.txt in this directory for details of the common pinctrl
+    bindings used by client devices, including the meaning of the phrase "pin configuration
+    node".
+
+    Tegra's pin configuration nodes act as a container for an arbitrary number of subnodes. Each
+    of these subnodes represents some desired configuration for a pin, a group, or a list of
+    pins or groups. This configuration can include the mux function to select on those pin(s)/
+    group(s), and various pin configuration parameters, such as pull-up, tristate, drive
+    strength, etc.
+
+    The name of each subnode is not important; all subnodes should be enumerated and processed
+    purely based on their content.
+
+    Each subnode only affects those parameters that are explicitly listed. In other words, a
+    subnode that lists a mux function but no pin configuration parameters implies no information
+    about any pin configuration parameters.
+
+    Similarly, a pin subnode that describes a pullup parameter implies no information about e.g.
+    the mux function or tristate parameter. For this reason, even seemingly boolean values are
+    actually tristates in this binding: unspecified, off, or on. Unspecified is represented as
+    an absent property, and off/on are represented as integer values 0 and 1.
+
+    Note that many of these properties are only valid for certain specific pins or groups. See
+    the Tegra TRM and various pinmux spreadsheets for complete details regarding which groups
+    support which functionality. The Linux pinctrl driver may also be a useful reference, since
+    it consolidates, disambiguates, and corrects data from all those sources.

-NVIDIA Tegra124 pinmux controller
-
-The Tegra124 pinctrl binding is very similar to the Tegra20 and Tegra30
-pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
-nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
-a baseline, and only documents the differences between the two bindings.
-
-Required properties:
-- compatible: For Tegra124, must contain "nvidia,tegra124-pinmux".  For
-  Tegra132, must contain '"nvidia,tegra132-pinmux", "nvidia-tegra124-pinmux"'.
-- reg: Should contain a list of base address and size pairs for:
-    -- first entry - the drive strength and pad control registers.
-    -- second entry - the pinmux registers
-    -- third entry - the MIPI_PAD_CTRL register
-
-Tegra124 adds the following optional properties for pin configuration subnodes.
-The macros for options are defined in the
-	include/dt-binding/pinctrl/pinctrl-tegra.h.
-- nvidia,enable-input: Integer. Enable the pin's input path.
-		enable :TEGRA_PIN_ENABLE and
-		disable or output only: TEGRA_PIN_DISABLE.
-- nvidia,open-drain: Integer.
-		enable: TEGRA_PIN_ENABLE.
-		disable: TEGRA_PIN_DISABLE.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
-    until reset.
-		enable: TEGRA_PIN_ENABLE.
-		disable: TEGRA_PIN_DISABLE.
-- nvidia,io-reset: Integer. Reset the IO path.
-		enable: TEGRA_PIN_ENABLE.
-		disable: TEGRA_PIN_DISABLE.
-- nvidia,rcv-sel: Integer. Select VIL/VIH receivers.
-		normal: TEGRA_PIN_DISABLE
-		high: TEGRA_PIN_ENABLE
-
-Please refer the Tegra TRM for complete details regarding which groups
-support which functionality.
-
-Valid values for pin and group names are:
-
-  per-pin mux groups:
-
-    These all support nvidia,function, nvidia,tristate, nvidia,pull,

+  description: |
+    Tegra's pin configuration nodes act as containers for an arbitrary number of subnodes. Each of
+    these subnodes represents some desired configuration for a pin, a group, or a list of pins or
+    groups. This configuration can include the mux function to select on those pin(s)/group(s), and
+    various pin configuration parameters, such as pull-up, tristate, drive strength, etc.
+
+    The name of each subnode is not important; all subnodes should be enumerated and processed
+    purely based on their content.
+
+    Each subnode only affects those parameters that are explicitly listed. In other words, a
+    subnode that lists a mux function but no pin configuration parameters implies no information
+    about any pin configuration parameters. Similarly, a pin subnode that describes a pullup
+    parameter implies no information about e.g. the mux function or tristate parameter. For this
+    reason, even seemingly boolean values are actually tristates in this binding: unspecified, off,
+    or on. Unspecified is represented as an absent property, and off/on are represented as integer
+    values 0 and 1.
+
+    See the TRM to determine which properties and values apply to each pin/group. Macro values for
+    property values are defined in include/dt-binding/pinctrl/pinctrl-tegra.h.

-NVIDIA Tegra194 pinmux controller
-
-Required properties:
-- compatible: "nvidia,tegra194-pinmux"
-- reg: Should contain a list of base address and size pairs for:
-  - first entry: The APB_MISC_GP_*_PADCTRL registers (pad control)
-  - second entry: The PINMUX_AUX_* registers (pinmux)
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Tegra's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, tristate, drive strength, etc.
-
-See the TRM to determine which properties and values apply to each pin/group.
-Macro values for property values are defined in
-include/dt-binding/pinctrl/pinctrl-tegra.h.
-
-Required subnode-properties:
-- nvidia,pins : An array of strings. Each string contains the name of a pin or
-    group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- nvidia,function: A string containing the name of the function to mux to the
-    pin or group.
-- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
-    0: none, 1: down, 2: up.
-- nvidia,tristate: Integer.
-    0: drive, 1: tristate.
-- nvidia,enable-input: Integer. Enable the pin's input path.
-    enable :TEGRA_PIN_ENABLE and
-    disable or output only: TEGRA_PIN_DISABLE.
-- nvidia,open-drain: Integer.
-    enable: TEGRA_PIN_ENABLE.
-    disable: TEGRA_PIN_DISABLE.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
-    until reset.
-    enable: TEGRA_PIN_ENABLE.
-    disable: TEGRA_PIN_DISABLE.
-- nvidia,io-hv: Integer. Select high-voltage receivers.
-    normal: TEGRA_PIN_DISABLE
-    high: TEGRA_PIN_ENABLE
-- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
-    normal: TEGRA_PIN_DISABLE
-    high: TEGRA_PIN_ENABLE
-- nvidia,drive-type: Integer. Valid range 0...3.
-- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
-    Tegra TRM.
-- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
-    Tegra TRM.
-
-Valid values for pin and group names (nvidia,pin) are:
-
-    These correspond to Tegra PADCTL_* (pinmux) registers.
-
-  Mux groups:
-
-    These correspond to Tegra PADCTL_* (pinmux) registers. Any property
-    that exists in those registers may be set for the following pin names.
-
-    pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
-
-  Drive groups:
-
-    These registers controls a single pin for which a mux group exists.
-    See the list above for the pin name to use when configuring the pinmux.
-
-    pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
-
-Valid values for nvidia,functions are:
-
-    pe5
-
-Power Domain:
-    pex_l5_clkreq_n_pgg0 and pex_l5_rst_n_pgg1 are part of PCIE C5 power
-    partition. Client devices must enable this partition before accessing
-    these pins here.
-
-
-Example:
-
-		tegra_pinctrl: pinmux: pinmux@2430000 {
-			compatible = "nvidia,tegra194-pinmux";
-			reg = <0x2430000 0x17000

-
-			pinctrl-names = "pex_rst";
-			pinctrl-0 = <&pex_rst_c5_out_state>;
-
-			pex_rst_c5_out_state: pex_rst_c5_out {

-NVIDIA Tegra20 pinmux controller
-
-Required properties:
-- compatible: "nvidia,tegra20-pinmux"
-- reg: Should contain the register physical address and length for each of
-  the tri-state, mux, pull-up/down, and pad control register sets.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Tegra's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, tristate, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function or tristate parameter. For this
-reason, even seemingly boolean values are actually tristates in this binding:
-unspecified, off, or on. Unspecified is represented as an absent property,
-and off/on are represented as integer values 0 and 1.
-
-Required subnode-properties:
-- nvidia,pins : An array of strings. Each string contains the name of a pin or
-    group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- nvidia,function: A string containing the name of the function to mux to the
-  pin or group. Valid values for function names are listed below. See the Tegra
-  TRM to determine which are valid for each pin or group.
-- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
-    0: none, 1: down, 2: up.
-- nvidia,tristate: Integer.
-    0: drive, 1: tristate.
-- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
-    0: no, 1: yes.
-- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
-    0: no, 1: yes.
-- nvidia,low-power-mode: Integer. Valid values 0-3. 0 is least power, 3 is
-    most power. Controls the drive power or current. See "Low Power Mode"
-    or "LPMD1" and "LPMD0" in the Tegra TRM.
-- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
-    Tegra TRM.
-- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
-    Tegra TRM.
-- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
-    fastest. The range of valid values depends on the pingroup. See
-    "DRVDN_SLWR" in the Tegra TRM.
-- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
-    fastest. The range of valid values depends on the pingroup. See
-    "DRVUP_SLWF" in the Tegra TRM.
-
-Note that many of these properties are only valid for certain specific pins
-or groups. See the Tegra TRM and various pinmux spreadsheets for complete
-details regarding which groups support which functionality. The Linux pinctrl
-driver may also be a useful reference, since it consolidates, disambiguates,
-and corrects data from all those sources.

-NVIDIA Tegra210 pinmux controller
-
-Required properties:
-- compatible: "nvidia,tegra210-pinmux"
-- reg: Should contain a list of base address and size pairs for:
-  - first entry: The APB_MISC_GP_*_PADCTRL registers (pad control)
-  - second entry: The PINMUX_AUX_* registers (pinmux)
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Tegra's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, tristate, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function or tristate parameter. For this
-reason, even seemingly boolean values are actually tristates in this binding:
-unspecified, off, or on. Unspecified is represented as an absent property,
-and off/on are represented as integer values 0 and 1.
-
-See the TRM to determine which properties and values apply to each pin/group.
-Macro values for property values are defined in
-include/dt-binding/pinctrl/pinctrl-tegra.h.
-
-Required subnode-properties:
-- nvidia,pins : An array of strings. Each string contains the name of a pin or
-    group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- nvidia,function: A string containing the name of the function to mux to the
-    pin or group.
-- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
-    0: none, 1: down, 2: up.
-- nvidia,tristate: Integer.
-    0: drive, 1: tristate.
-- nvidia,enable-input: Integer. Enable the pin's input path.
-    enable :TEGRA_PIN_ENABLE and
-    disable or output only: TEGRA_PIN_DISABLE.
-- nvidia,open-drain: Integer.
-    enable: TEGRA_PIN_ENABLE.
-    disable: TEGRA_PIN_DISABLE.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
-    until reset.
-    enable: TEGRA_PIN_ENABLE.
-    disable: TEGRA_PIN_DISABLE.
-- nvidia,io-hv: Integer. Select high-voltage receivers.
-    normal: TEGRA_PIN_DISABLE
-    high: TEGRA_PIN_ENABLE
-- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
-    normal: TEGRA_PIN_DISABLE
-    high: TEGRA_PIN_ENABLE
-- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
-    normal: TEGRA_PIN_DISABLE
-    high: TEGRA_PIN_ENABLE
-- nvidia,drive-type: Integer. Valid range 0...3.
-- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
-    Tegra TRM.
-- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
-    The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
-    Tegra TRM.
-- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
-    fastest. The range of valid values depends on the pingroup. See
-    "DRVDN_SLWR" in the Tegra TRM.
-- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
-    fastest. The range of valid values depends on the pingroup. See
-    "DRVUP_SLWF" in the Tegra TRM.

-NVIDIA Tegra30 pinmux controller
-
-The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
-as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
-that binding as a baseline, and only documents the differences between the
-two bindings.
-
-Required properties:
-- compatible: "nvidia,tegra30-pinmux"
-- reg: Should contain the register physical address and length for each of
-  the pad control and mux registers.
-
-Tegra30 adds the following optional properties for pin configuration subnodes:
-- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
-- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
-    until reset. 0: no, 1: yes.
-- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
-
-As with Tegra20, see the Tegra TRM for complete details regarding which groups
-support which functionality.
-
-Valid values for pin and group names are:
-
-  per-pin mux groups:
-
-    These all support nvidia,function, nvidia,tristate, nvidia,pull,
-    nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
-    nvidia,io-reset.

+    Please refer to pinctrl-bindings.txt in this directory for details of the common pinctrl
+    bindings used by client devices, including the meaning of the phrase "pin configuration
+    node".
+
+    Tegra's pin configuration nodes act as a container for an arbitrary number of subnodes. Each
+    of these subnodes represents some desired configuration for a pin, a group, or a list of
+    pins or groups. This configuration can include the mux function to select on those pin(s)/
+    group(s), and various pin configuration parameters, such as pull-up, tristate, drive
+    strength, etc.
+
+    The name of each subnode is not important; all subnodes should be enumerated and processed
+    purely based on their content.
+
+    Each subnode only affects those parameters that are explicitly listed. In other words, a
+    subnode that lists a mux function but no pin configuration parameters implies no information
+    about any pin configuration parameters.
+
+    Similarly, a pin subnode that describes a pullup parameter implies no information about e.g.
+    the mux function or tristate parameter. For this reason, even seemingly boolean values are
+    actually tristates in this binding: unspecified, off, or on. Unspecified is represented as
+    an absent property, and off/on are represented as integer values 0 and 1.
+
+    Note that many of these properties are only valid for certain specific pins or groups. See
+    the Tegra TRM and various pinmux spreadsheets for complete details regarding which groups
+    support which functionality. The Linux pinctrl driver may also be a useful reference, since
+    it consolidates, disambiguates, and corrects data from all those sources.
