Commit Message

Bhumkar, Tejas Arvind March 21, 2024, 8:52 a.m. UTC 
Since the zynqmp pinctrl driver now includes support for the
tri-state registers, ensure that the pins needing output-enable
are correctly configured for SOMs.

Currently, there is an issue with the detection of the MMC for
the SOM kv260, resulting in the following error:
ZynqMP> mmc dev 1
Card did not respond to voltage select! : -110

To address this problem, configure the SDIO pins for output-enable
to enable MMC detection.
