TI Palam 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.

+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,palams-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 abitrary 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, 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,palams-enable-dvfs1: Enable DVFS1. Configure pins for DVFS1 mode.
+- ti,palams-enable-dvfs2: Enable DVFS2. Configure pins for DVFS2 mode.
+
+Required subnode-properties:
+- ti,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:
+- ti,function: string containing the name of the function to mux to the
+ pin or group. Valid values for function names are listed below. Please
+ refer the datasheet of the device to determine which are valid for each
+ pin or group.
+- ti,pull: Integer, representing the pull-down/up to apply to the pin.
+ 0: none, 1: up, 2: down.
+- ti,open-drain" Integer, representing the open drain to be enable/disable
+ to the pin.
+ 0: Disable, 1: Enable.
+
+
+Note that many of these properties are only valid for certain specific pins
+or groups. See the Palma device datasheet for complete details regarding which
+groups support which functionality.
+
+Valid values for pin and group names are:
+pins: gpio0_id, gpio1_vbus_det_led1_pwm1, gpio2_regen_led2_pwm2, gpio3_chrg_det,
+ gpio4_sysen1, gpio5_clk32kgaudio_usb_psel, gpio6_sysen2,
+ gpio7_msecure_pwrhold, gpio8_sim1rsti, gpio9_low_vbat,
+ gpio10_wireless_chrg1, gpio11_rcm, gpio12_sim2rsto, gpio13, gpio14,
+ gpio15_sim2rsti, vac, powergood_usb_psel, nreswarm, pwrdown,
+ gpadc_start, reset_in, nsleep, enable1, enable2, int.
+
+function: 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.
+
+Example:
+ palmas: tps65913@58 {
+ :::::::::::
+
+ pinctrl {
+ compatible = "ti,tps65913-pinctrl";
+ ti,palams-enable-dvfs1;
+ pinctrl-names = "default";
+ pinctrl-0 = <&palmas_pins_state>;
+
+ palmas_pins_state: pinmux {
+ gpio0_id {
+ ti,pins = "gpio0_id";
+ ti,function = "id";
+ };
+
+ vac {
+ ti,pins = "vac";
+ ti,function = "vacok";
+ };
