ti,k3-pinctrl
Vendor: Texas Instruments
Description
TI K3 pinctrl node.
Pins can be configured using the following macro "K3_PINMUX(offset, value, mux_mode)".
offset - the pin attribute register offset from the base address.
value - one of the following:
PIN_OUTPUT
PIN_OUTPUT_PULLUP
PIN_OUTPUT_PULLDOWN
PIN_INPUT
PIN_INPUT_PULLUP
PIN_INPUT_PULLDOWN
mux_mode - The mux mode for the pin, MUX_MODE_0 -> MUX_MODE_9.
e.g. for AM62x the pinctrl base address is 0xf4000.
The default UART0_RX pin is located at 0x000f41c8 (mux mode 0).
So the configuration would be "K3_PINMUX(0x1c8, PIN_INPUT, MUX_MODE_0)".

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
