-* 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: should be
- "rockchip,px30-pinctrl": for Rockchip PX30
- "rockchip,rv1108-pinctrl": for Rockchip RV1108
- "rockchip,rk2928-pinctrl": for Rockchip RK2928
- "rockchip,rk3066a-pinctrl": for Rockchip RK3066a

- "rockchip,rk3399-pinctrl": for Rockchip RK3399
- "rockchip,rk3568-pinctrl": for Rockchip RK3568
-
- - 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. On the rk3368 this should
- point to the PMUGRF syscon.
-
-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:
-See rockchip,gpio-bank.yaml
-
-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.
