+  subnode format:
+    description:
+      A pinctrl node should contain at least one subnodes representing the
+      pinctrl groups 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 strength, input enable/disable and
+      input schmitt.
+
+      node {
+        pinmux = <PIN_NUMBER_PINMUX>;
+        GENERIC_PINCONFIG;
+      };
+  '-pinmux$':
+    description:
+      Integer array, represents gpio pin number and mux setting.
+      Supported pin number and mux varies for different SoCs, and are defined
+      as macros in dt-bindings/pinctrl/<soc>-pinfunc.h directly.
+    $ref: "/schemas/pinctrl/pincfg-node.yaml"
+
+  GENERIC_PINCONFIG:
+    description:
+      It is the generic pinconfig options to use, bias-disable,
+      bias-pull-down, bias-pull-up, input-enable, input-disable, output-low,
+      output-high, input-schmitt-enable, input-schmitt-disable
+      and drive-strength are valid.
+
+      Some special pins have extra pull up strength, there are R0 and R1 pull-up
+      resistors available, but for user, it's only need to set R1R0 as 00, 01,
+      10 or 11. So It needs config "mediatek,pull-up-adv" or
+      "mediatek,pull-down-adv" to support arguments for those special pins.
+      Valid arguments are from 0 to 3.
+
+      We can use "mediatek,tdsel" which is an integer describing the steps for
+      output level shifter duty cycle when asserted (high pulse width adjustment).
+      Valid arguments  are from 0 to 15.
+      We can use "mediatek,rdsel" which is an integer describing the steps for
+      input level shifter duty cycle when asserted (high pulse width adjustment).
+      Valid arguments are from 0 to 63.
+
+      When config drive-strength, it can support some arguments, such as
+      MTK_DRIVE_4mA, MTK_DRIVE_6mA, etc. See dt-bindings/pinctrl/mt65xx.h.
+      It can only support 2/4/6/8/10/12/14/16mA in mt8192.
+      For I2C pins, there are existing generic driving setup and the specific
+      driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA driving
+      adjustment in generic driving setup. But in specific driving setup,
+      they can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+      driving setup for I2C pins, the existing generic driving setup will be
+      disabled. For some special features, we need the I2C pins specific
+      driving setup. The specific driving setup is controlled by E1E0EN.
+      So we need add extra vendor driving preperty instead of
+      the generic driving property.
+      We can add "mediatek,drive-strength-adv = <XXX>;" to describe the specific
+      driving setup property. "XXX" means the value of E1E0EN. EN is 0 or 1.
+      It is used to enable or disable the specific driving setup.
+      E1E0 is used to describe the detail strength specification of the I2C pin.
+      When E1=0/E0=0, the strength is 0.125mA.
+      When E1=0/E0=1, the strength is 0.25mA.
+      When E1=1/E0=0, the strength is 0.5mA.
+      When E1=1/E0=1, the strength is 1mA.
+      So the valid arguments of "mediatek,drive-strength-adv" are from 0 to 7.
