-Qualcomm Atheros IPQ4019 TLMM block
-
-This is the Top Level Mode Multiplexor block found on the Qualcomm IPQ8019
-platform, it provides pinctrl, pinmux, pinconf, and gpiolib facilities.
-
-Required properties:
-- compatible: "qcom,ipq4019-pinctrl"
-- reg: Should be the base address and length of the TLMM block.
-- interrupts: Should be the parent IRQ of the TLMM block.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be two.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two.
- The first cell is the gpio pin number and the
- second cell is used for optional parameters.
-- gpio-ranges: see ../gpio/gpio.txt
-
-Optional properties:
-
-- gpio-reserved-ranges: see ../gpio/gpio.txt
-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-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".
-
-The 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, 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.
-
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
- pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-open-drain,
- drive-strength.
-
-Non-empty subnodes must specify the 'pins' property.
-Note that not all properties are valid for all pins.
-
-
-Valid values for qcom,pins are:
- gpio0-gpio99
- Supports mux, bias and drive-strength
-
-Valid values for qcom,function are:
-aud_pin, audio_pwm, blsp_i2c0, blsp_i2c1, blsp_spi0, blsp_spi1, blsp_uart0,
-blsp_uart1, chip_rst, gpio, i2s_rx, i2s_spdif_in, i2s_spdif_out, i2s_td, i2s_tx,
-jtag, led0, led1, led2, led3, led4, led5, led6, led7, led8, led9, led10, led11,
-mdc, mdio, pcie, pmu, prng_rosc, qpic, rgmii, rmii, sdio, smart0, smart1,
-smart2, smart3, tm, wifi0, wifi1
-
-Example:
-
- tlmm: pinctrl@1000000 {
- compatible = "qcom,ipq4019-pinctrl";
- reg = <0x1000000 0x300000>;
-
- gpio-controller;
- #gpio-cells = <2>;
- gpio-ranges = <&tlmm 0 0 100>;
- interrupt-controller;
- #interrupt-cells = <2>;
- interrupts = <0 208 0>;
-
- serial_pins: serial_pinmux {
- mux {
- pins = "gpio60", "gpio61";
- function = "blsp_uart0";
- bias-disable;
- };
- };
- };
