+NVIDIA Tegra194 pinmux controller
+
+Required properties:
+- compatible: "nvidia,tegra194-pinmux"
+- reg: Should contain a list of base address and size pairs for:
+ - first entry: The APB_MISC_GP_*_PADCTRL registers (pad control)
+ - second entry: The PINMUX_AUX_* registers (pinmux)
+
+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".
+
+Tegra'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, tristate, drive strength, etc.
+
+See the TRM to determine which properties and values apply to each pin/group.
+Macro values for property values are defined in
+include/dt-binding/pinctrl/pinctrl-tegra.h.
+
+Required subnode-properties:
+- nvidia,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:
+- nvidia,function: A string containing the name of the function to mux to the
+ pin or group.
+- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
+ 0: none, 1: down, 2: up.
+- nvidia,tristate: Integer.
+ 0: drive, 1: tristate.
+- nvidia,enable-input: Integer. Enable the pin's input path.
+ enable :TEGRA_PIN_ENABLE and
+ disable or output only: TEGRA_PIN_DISABLE.
+- nvidia,open-drain: Integer.
+ enable: TEGRA_PIN_ENABLE.
+ disable: TEGRA_PIN_DISABLE.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+ until reset.
+ enable: TEGRA_PIN_ENABLE.
+ disable: TEGRA_PIN_DISABLE.
+- nvidia,io-hv: Integer. Select high-voltage receivers.
+ normal: TEGRA_PIN_DISABLE
+ high: TEGRA_PIN_ENABLE
+- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
+ normal: TEGRA_PIN_DISABLE
+ high: TEGRA_PIN_ENABLE
+- nvidia,drive-type: Integer. Valid range 0...3.
+- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
+ The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
+ Tegra TRM.
+- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
+ The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
+ Tegra TRM.
+
+Valid values for pin and group names (nvidia,pin) are:
+
+ These correspond to Tegra PADCTL_* (pinmux) registers.
+
+ Mux groups:
+
+ These correspond to Tegra PADCTL_* (pinmux) registers. Any property
+ that exists in those registers may be set for the following pin names.
+
+ pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
+
+ Drive groups:
+
+ These registers controls a single pin for which a mux group exists.
+ See the list above for the pin name to use when configuring the pinmux.
+
+ pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
+
+Valid values for nvidia,functions are:
+
+ pe5
+
+Power Domain:
+ pex_l5_clkreq_n_pgg0 and pex_l5_rst_n_pgg1 are part of PCIE C5 power
+ partition. Client devices must enable this partition before accessing
+ these pins here.
+
+
+Example:
+
+ tegra_pinctrl: pinmux: pinmux@2430000 {
+ compatible = "nvidia,tegra194-pinmux";
+ reg = <0x2430000 0x17000

+
+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".
+
+The 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.
+
+
+PIN CONFIGURATION NODES:
+
+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:

-* STM32 GPIO and Pin Mux/Config controller
-
-STMicroelectronics's STM32 MCUs intregrate a GPIO and Pin mux/config hardware

-also provides ability to multiplex and configure the output of various on-chip
-controllers onto these pads.
-
-Pin controller node:
-Required properies:

- - ranges : defines mapping between pin controller node (parent) to
- gpio-bank node (children).

- a gpio controller. Format is <&phandle a b c> with:
- -(phandle): phandle of pin-controller.
- -(a): gpio base offset in range.
- -(b): pin base offset in range.
- -(c): gpio count in range
- This entry has to be used either if there are holes inside a bank:
- GPIOB0/B1/B2/B14/B15 (see example 2)
- or if banks are not contiguous:
- GPIOA/B/C/E...
- NOTE: If "gpio-ranges" is used for a gpio controller, all gpio-controller
- have to use a "gpio-ranges" entry.
- More details in Documentation/devicetree/bindings/gpio/gpio.txt.

- used to select GPIOs as interrupts).

-Contents of function subnode node:
-----------------------------------
-Subnode format
-A pinctrl node should contain at least one subnode representing the
-pinctrl group available on the machine. Each subnode will list the
-pins it needs, and how they should be configured, with regard to muxer
-configuration, pullups, drive, output high/low and output speed.
-
- node {
- pinmux = <PIN_NUMBER_PINMUX>;
- GENERIC_PINCONFIG;
- };
-
-Required properties:
-- pinmux: integer array, represents gpio pin number and mux setting.
- Supported pin number and mux varies for different SoCs, and are defined in
- dt-bindings/pinctrl/<soc>-pinfunc.h directly.
- These defines are calculated as:
- ((port * 16 + line) << 8) | function
- With:
- - port: The gpio port index (PA = 0, PB = 1, ..., PK = 11)
- - line: The line offset within the port (PA0 = 0, PA1 = 1, ..., PA15 = 15)
- - function: The function number, can be:
- * 0 : GPIO
- * 1 : Alternate Function 0
- * 2 : Alternate Function 1
- * 3 : Alternate Function 2
- * ...
- * 16 : Alternate Function 15
- * 17 : Analog
-
- To simplify the usage, macro is available to generate "pinmux" field.
- This macro is available here:
- - include/dt-bindings/pinctrl/stm32-pinfunc.h
-
- Some examples of using macro:
- /* GPIO A9 set as alernate function 2 */
- ... {
- pinmux = <STM32_PINMUX('A', 9, AF2)>;
- };
- /* GPIO A9 set as GPIO */
- ... {
- pinmux = <STM32_PINMUX('A', 9, GPIO)>;
- };
- /* GPIO A9 set as analog */
- ... {
- pinmux = <STM32_PINMUX('A', 9, ANALOG)>;
- };
-
-Optional properties:
-- GENERIC_PINCONFIG: is the generic pinconfig options to use.
- Available options are:
- - bias-disable,
- - bias-pull-down,
- - bias-pull-up,
- - drive-push-pull,
- - drive-open-drain,
- - output-low
- - output-high
- - slew-rate = <x>, with x being:
- < 0 > : Low speed
- < 1 > : Medium speed
- < 2 > : Fast speed
- < 3 > : High speed
-
-Example:
-
-pin-controller {
-...
- usart1_pins_a: usart1@0 {
- pins1 {
- pinmux = <STM32_PINMUX('A', 9, AF7)>;
- bias-disable;
- drive-push-pull;
- slew-rate = <0>;
- };
- pins2 {
- pinmux = <STM32_PINMUX('A', 10, AF7)>;
- bias-disable;
