671 This selects the pinctrl driver for Xilinx ZynqMP platform.
672 This driver will query the pin information from the firmware
673 and allow configuring the pins.
674 Configuration can include the mux function to select on those
675 pin(s)/group(s), and various pin configuration parameters
676 such as pull-up, slew rate, etc.
677 This driver can also be built as a module. If so, the module
678 will be called pinctrl-zynqmp.
