[U-Boot] [PATCH 0/3] gpio: zynq: Add support for Versal
Hi,
this patchset is updating existing zynq driver with adding two layout. One for Versal gpio and another one on PMC gpio which is using different layout. And also enabling gpio command for versal.
Thanks, Michal

Enable GPIO command for Xilinx Versal platform. Driver is updated that's why it can be used directly. Driver is enabled by default through Kconfig.
