[PATCH 0/7] MMC updates for TI K3 platforms

[PATCH 0/7] MMC updates for TI K3 platforms

[Judith Mendez]

This patch series includes MMC updates for various TI K3 platforms.

It includes support for enabling UHS/SDR104 bus modes or removing
HS400 support due to CQE errors seen during boot.

For AM62ax, add missing UHS support.

For AM65x, fix ITAP delay and OTAP delay and clkbuf-sel properties
in SDHCI nodes.

[PATCH 1/7] arm64: dts: ti: k3-am65-main: Update sdhci properties

[Judith Mendez]

Update otap-del-sel properties as per datasheet [0].

Add missing clkbuf-sel and itap-del-sel values also as per
datasheet [0].

Move clkbuf-sel and ti,trm-icp above the otap-del-sel properties
so the sdhci nodes could be more uniform across platforms.

This is just WA to get rid of CQE errors. I prefer to hold this patch 
under debug from hardware side is not complete.

Moreover, CQE errors are seen with 32GB variant not with 16GB, So we can 
not blame controller for this

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
