Hi all,

This series adds a GPIO driver for the Xilinx Zynq/Zynq
UltraScale+ MPSoC architecture based on the corresponding
driver in the Linux kernel.

The work was mainly carried out by Thomas Haemmerle with
a few additions by Michael Tretter. After applying several
format fixes, I tested the driver on the ZCU106 evaluation
board as well as on a custom Zynq UltraScale+ MPSoC board.
Looking forward to your comments!

The second patch depends on the recently submitted addition
of support for the ZCU106 evaluation board [0].

Best regards,
