[PATCH V3 3/3] pinctrl: palmas: add pincontrol driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



TI Palmas series Power Management IC have multiple pins which can be
configured for different functionality. This pins can be configured
for different function. Also their properties like pull up/down,
open drain enable/disable are configurable.

Add support for pincontrol driver Palmas series device like TPS65913,
TPS80036. The driver supports to be register from DT only.

---
Changes from V1:
- Add generic property for pins and functions in pinconf-generic.
- Add APIs to map the DT and subnode.
- Move common utils APIs to the pinctrl-utils from this file.
- Update the binding document accordingly.
Changes from V2:
- Add ack by Lee.
- Correct the binding docs.

+Palmas Pincontrol bindings
+
+The pins of Palmas device can be set on different option and provides
+the configuration for Pull UP/DOWN, open drain etc.
+
+Required properties:
+- compatible: It must be one of following:
+  - "ti,palmas-pinctrl" for Palma series of the pincontrol.
+  - "ti,tps65913-pinctrl" for Palma series device TPS65913.
+  - "ti,tps80036-pinctrl" for Palma series device TPS80036.
+
+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".
+
+Palmas's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+list of pins. This configuration can include the mux function to select on
+those pin(s), and various pin configuration parameters, such as pull-up,
+open drain.
+
+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.
+
+Optional properties:
+- ti,palmas-enable-dvfs1: Enable DVFS1. Configure pins for DVFS1 mode.
+	Selection primary or secondary function associated to I2C2_SCL_SCE,
+	I2C2_SDA_SDO pin/pad for DVFS1 interface
+- ti,palmas-enable-dvfs2: Enable DVFS2. Configure pins for DVFS2 mode.
+	Selection primary or secondary function associated to GPADC_START
+	and SYSEN2 pin/pad for DVFS2 interface
+
+This binding uses the following generic properties as defined in
+pinctrl-bindings.txt:
+
+Required: pins
+Options: function, bias-disable, bias-pull-up, bias-pull-down,
+	 bias-pin-default, drive-open-drain.
+
+Note that many of these properties are only valid for certain specific pins.
+See the Palmas device datasheet for complete details regarding which pins
+support which functionality.
+
+Valid values for pin names are:
+	gpio0, gpio1, gpio2, gpio3, gpio4, gpio5, gpio6, gpio7, gpio8, gpio9,
+	gpio10, gpio11, gpio12, gpio13, gpio14, gpio15, vac, powergood,
+	nreswarm, pwrdown, gpadc_start, reset_in, nsleep, enable1, enable2,
+	int.
+
+Valid value of function names are:
+	gpio, led, pwm, regen, sysen, clk32kgaudio, id, vbus_det, chrg_det,
+	vac, vacok, powergood, usb_psel, msecure, pwrhold, int, nreswarm,
+	simrsto, simrsti, low_vbat, wireless_chrg1, rcm, pwrdown, gpadc_start,
+	reset_in, nsleep, enable.
+
+There are 4 special functions: opt0, opt1, opt2 and opt3. If any of these
+functions is selected then directly pins register will be written with 0, 1, 2
+or 3 respectively if it is valid for that pins or list of pins.
+
+Example:
+	palmas: tps65913 {
+		....	
+		pinctrl {
+			compatible = "ti,tps65913-pinctrl";
+			ti,palmas-enable-dvfs1;
+			pinctrl-names = "default";
+			pinctrl-0 = <&palmas_pins_state>;
+
+			palmas_pins_state: pinmux {
+				gpio0 {
+					pins = "gpio0";
+					function = "id";
+					bias-pull-up;
+				};
+
+				vac {
+					pins = "vac";
+					function = "vacok";
+					bias-pull-down;
+				};
+
+				gpio5 {
+					pins = "gpio5";
+					function = "opt0";
+					drive-open-drain = <1>;
+				};
+			};
+		};
+		....	
+	};
