-Qualcomm IPQ8064 TLMM block
-
-Required properties:
-- compatible: "qcom,ipq8064-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".
-
-Qualcomm's 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-strength,
- output-low, output-high.
-
-Non-empty subnodes must specify the 'pins' property.
-
-Valid values for qcom,pins are:
- gpio0-gpio68
- Supports mux, bias, and drive-strength
-
- sdc3_clk, sdc3_cmd, sdc3_data
- Supports bias and drive-strength
-
-
-Valid values for function are:
- mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gpio, gsbi1, gsbi2, gsbi4, gsbi5,
- gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
- spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
- pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,
- pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
- pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
- pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold

-Example:
-
- pinmux: pinctrl@800000 {
- compatible = "qcom,ipq8064-pinctrl";
- reg = <0x800000 0x4000>;
-

- #gpio-cells = <2>;
- gpio-ranges = <&pinmux 0 0 69>;

- interrupts = <0 32 0x4>;
-
- pinctrl-names = "default";
- pinctrl-0 = <&gsbi5_uart_default>;
-
- gsbi5_uart_default: gsbi5_uart_default {
- mux {
- pins = "gpio18", "gpio19";
- function = "gsbi5";
- };
-
- tx {
- pins = "gpio18";
- drive-strength = <4>;

- };
-
- rx {
- pins = "gpio19";
- drive-strength = <2>;
