Queued as a fix for v5.1-rc, I see that this is being fixed in the driver also, but I think fixing the DTs is necessary also. Kevin
Hi, some nit-picks as well as my Tested-by (in case it's not too late) below. thank you for taking care of this!

Hence why I tagged the commit from which the platform was not acting correctly anymore. If that's fine for you it's fine for me as well :) >>> Signed-off-by: Loys Ollivier <lollivier@baylibre.com> >> on my Khadas VIM(1), using Kevin's v5.0/fixes branch: >> Tested-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> > > I can add this tested-by tag in my v5.0/fixes branch for now, and can > replace it with a follow up if Loys can update the changelog with your > suggestions/clarifications. > Will do. > Thanks, > > Kevin

Commit 89a5e15bcba8 ("gpio/mmc/of: Respect polarity in the device tree") changed the behavior of "cd-inverted" to follow the device tree bindings specification. Lines specifying "cd-inverted" are now "active high". Fix the SD card for meson by setting the cd-gpios as "active low" according to the boards specifications.
