-Qualcomm MSM8x74 TLMM block
-
-Required properties:
-- compatible: "qcom,msm8x74-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.
-
-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".
-
-Qualcomm'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, 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-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-gpio145
- Supports mux, bias and drive-strength
-
- sdc1_clk, sdc1_cmd, sdc1_data, sdc2_clk, sdc2_cmd, sdc2_data
- Supports bias and drive-strength
-
-Valid values for qcom,function are:
- blsp_i2c2, blsp_i2c6, blsp_i2c11, blsp_spi1, blsp_uart2, blsp_uart8, slimbus
-
- (Note that this is not yet the complete list of functions)

-Example:
-
- msmgpio: pinctrl@fd510000 {
- compatible = "qcom,msm8x74-pinctrl";
- reg = <0xfd510000 0x4000>;
-
- gpio-controller;
- #gpio-cells = <2>;
- interrupt-controller;
- #interrupt-cells = <2>;
- interrupts = <0 208 0>;
-
- pinctrl-names = "default";
- pinctrl-0 = <&uart2_default>;
-
- uart2_default: uart2_default {
- mux {
- qcom,pins = "gpio4", "gpio5";
- qcom,function = "blsp_uart2";
- };
-
- tx {
- qcom,pins = "gpio4";
- drive-strength = <4>;
- bias-disable;
- };
-
- rx {
- qcom,pins = "gpio5";
- drive-strength = <2>;
- bias-pull-up;
- };
- };
- };
