xlnx,pinctrl-zynqmp

Vendor: Xilinx

Note

An implementation of a driver matching this compatible is available in drivers/pinctrl/pinctrl_xlnx_zynqmp.c.

Description

Xilinx ZynqMP SoC pinctrl node. It allows configuration of pin assignments
for the supported peripherals.

See Zynq UltraScale+ Devices Register Reference (UG1087) for details regarding
valid pin assignments

int

 
number of address cells in reg property

#size-cells

int

 
number of size cells in reg property

dmas

phandle-array

 
DMA channels specifiers

dma-names

string-array

 
Provided names of DMA channel specifiers

io-channels

phandle-array

#power-domain-cells

int

 
Number of cells in power-domains property

zephyr,deferred-init

boolean

 
Do not initialize device automatically on boot. Device should be manually
initialized using device_init().

wakeup-source

boolean

 
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.

zephyr,pm-device-runtime-auto

boolean

 
Automatically configure the device for runtime power management after the
init function runs.

zephyr,disabling-power-states

phandles

 
List of power states that will disable this device power.
