-* Rockchip Pinmux Controller
-
-The Rockchip Pinmux Controller, enables the IC
-to share one PAD to several functional blocks. The sharing is done by
-multiplexing the PAD input/output signals. For each PAD there are several
-muxing options with option 0 being the use as a GPIO.
-
-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 Rockchip pin configuration node is a node of a group of pins which can be
-used for a specific device or function. This node represents both mux and
-config of the pins in that group. The 'pins' selects the function mode(also
-named pin mode) this pin can work on and the 'config' configures various pad
-settings such as pull-up, etc.
-
-The pins are grouped into up to 5 individual pin banks which need to be
-defined as gpio sub-nodes of the pinmux controller.
-
-Required properties for iomux controller:
-  - compatible: one of "rockchip,rk2928-pinctrl", "rockchip,rk3066a-pinctrl"
-		       "rockchip,rk3066b-pinctrl", "rockchip,rk3188-pinctrl"
-		       "rockchip,rk3288-pinctrl"
-  - rockchip,grf: phandle referencing a syscon providing the
-	 "general register files"
-
-Optional properties for iomux controller:
-  - rockchip,pmu: phandle referencing a syscon providing the pmu registers
-	 as some SoCs carry parts of the iomux controller registers there.
-	 Required for at least rk3188 and rk3288.
-
-Deprecated properties for iomux controller:
-  - reg: first element is the general register space of the iomux controller
-	 It should be large enough to contain also separate pull registers.
-	 second element is the separate pull register space of the rk3188.
-	 Use rockchip,grf and rockchip,pmu described above instead.
-
-Required properties for gpio sub nodes:
-  - compatible: "rockchip,gpio-bank"
-  - reg: register of the gpio bank (different than the iomux registerset)
-  - interrupts: base interrupt of the gpio bank in the interrupt controller
-  - clocks: clock that drives this bank
-  - gpio-controller: identifies the node as a gpio controller and pin bank.
-  - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
-    binding is used, the amount of cells must be specified as 2. See generic
-    GPIO binding documentation for description of particular cells.
-  - interrupt-controller: identifies the controller node as interrupt-parent.
-  - #interrupt-cells: the value of this property should be 2 and the interrupt
-    cells should use the standard two-cell scheme described in
-    bindings/interrupt-controller/interrupts.txt
-
-Deprecated properties for gpio sub nodes:
-  - compatible: "rockchip,rk3188-gpio-bank0"
-  - reg: second element: separate pull register for rk3188 bank0, use
-	 rockchip,pmu described above instead
-
-Required properties for pin configuration node:
-  - rockchip,pins: 3 integers array, represents a group of pins mux and config
-    setting. The format is rockchip,pins = <PIN_BANK PIN_BANK_IDX MUX &phandle>.
-    The MUX 0 means gpio and MUX 1 to N mean the specific device function.
-    The phandle of a node containing the generic pinconfig options
-    to use, as described in pinctrl-bindings.txt in this directory.
