Subject: [PATCH 2/2] pinctrl: palmas: add pincontrol driver
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";
+ };
+ };
