it seems that this patch breaks SD card on my Khadas VIM and Khadas VIM2.
I used git bisect within this series to find that issue.
applying your .dts patches on top doesn't fix it

two boot logs attached:
* kvim-broken.txt has patches 1-5 (= including this patch) applied
* kvim-working.txt has only patches 1-4 (= excluding this patch) applied

Regards
Martin
