This selects the pinctrl driver for Xilinx ZynqMP platform.

|
This driver will query the pin information from the firmware
|
||
|
|
and allow configuring the pins.
|
||
|
|
Configuration can include the mux function to select on those
|
||
|
|
pin(s)/group(s), and various pin configuration parameters
|
||
|
|
such as pull-up, slew rate, etc.
|
||
|
|
This driver can also be built as a module. If so, the module
|
||
|
|
will be called pinctrl-zynqmp.
