Subject: [PATCH V2 1/3] arm64: dts: ti: k3-pinctrl: Define a generic GPIO MUX Mode
Introduce a GPIO mux mode macro for easier readability. All K3 devices
use mux mode 7 to switch to GPIO mux and this allows the gpio-ranges to
be defined for pinctrl-single clearly.
Signed-off-by: Nishanth Menon <nm@...com>

Changes since V1:
- Mux definition PIN_GPIO_RANGE_IOPAD instead of PIN_GPIO_MUX_MODE
- Added documentation as well to clarify the usage.
