-Qualcomm APQ8064 TLMM block
-
-Required properties:
-- compatible: "qcom,apq8064-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 pins are:
-  gpio0-gpio89
-
-Valid values for function are:
-  cam_mclk, codec_mic_i2s, codec_spkr_i2s, gp_clk_0a, gp_clk_0b, gp_clk_1a,
-  gp_clk_1b, gp_clk_2a, gp_clk_2b, gpio, gsbi1, gsbi2, gsbi3, gsbi4,
-  gsbi4_cam_i2c, gsbi5, gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6,
-  gsbi6_spi_cs1, gsbi6_spi_cs2, gsbi6_spi_cs3, gsbi7, gsbi7_spi_cs1,
-  gsbi7_spi_cs2, gsbi7_spi_cs3, gsbi_cam_i2c, hdmi, mi2s, riva_bt, riva_fm,
-  riva_wlan, sdc2, sdc4, slimbus, spkr_i2s, tsif1, tsif2, usb2_hsic, ps_hold
-

-
-	msmgpio: pinctrl@...000 {
-		compatible = "qcom,apq8064-pinctrl";
