As already stated in the other reply. These new compatible changes
needs to be discussed and acked before the driver starts using them.
In other words, make patch3 to precede this one.
but, then there will have a probe issue as mentioned in previous mail
list. that's why I separate the binding file changes to 2 patches.
That sounds seriously wrong. Aren't the bindings backwards compatible?
Kind regards
Uffe
As Matthias mentioned before:
"
NAK, this has to be:
You have to add the fallback compatible ("mediatek,mt8135-mmc") to
the binding
description as otherwise the driver does not get probed.
Regards,
Matthias
"
the original compatible in driver is "mediatek,mt8135-mmc", so that if
drop "mediatek,mt8135-mmc" in bindings file(User may refer it and drop
"mediatek,mt8135-mmc" in their DTS), the driver will not get probed.
If you change the driver as you did in this patch, then there is no probing problem.
Regards,
Matthias
