[PATCH v2 1/1] arm64: zynqmp: Add output-enable pins to SOMs

[Frager, Neal]

Hi Michal,

> kv260_gem3=mw 0xFF18020C 0xFC0 && gpio toggle gpio at ff0a000038 && \

Thank you for pointing this out.

You are correct as I was actually working from the
https://github.com/Xilinx/u-boot-xlnx/ master branch
which, as you know, is still based on u-boot 2023.01.

Looking at the upstream zynqmp-sck-kd-g-revA.dtso,
the output-enable defines are already included, so this
patch is unnecessary.

Please disregard this patch.  I will mark it as handled
elsewhere.

Best regards,
