Subject: [PATCH 0/4] arm64: tegra: Xavier SDMMC changes

Hi All,

I've encountered some issues with the Xavier while integrating some of our SDIO
modules. It turns out card detection was not working for the uSD socket and
I/Os were limited to 3.3 V. Also, the on-board eMMC module was using HS200 only.
I think it would make sense for the changes to go upstream. Please have a look.

Kind regards,
Tamas
