Re: [PATCH v3] arm64: dts: meson: Fix mmc cd-gpios polarity

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!

this depends on the polarity from the cd-gpios property. above commit
caused cd-inverted to be applied twice (effectively making it a
no-op). thus "cd-inverted" only means "active high" if cd-gpios also
sets GPIO_ACTIVE_HIGH. if the polarity in cd-gpios is GPIO_ACTIVE_LOW
together with "cd-inverted" then the GPIO will be treated as active
low.

not only switching to GPIO_ACTIVE_LOW, also dropping "cd-inverted"

in my patches for the 32-bit boards I used the commit which added SD
card support to the board for the Fixes tag. however, I'm fine with
this as well (I just wanted to point out that there's a small
difference in our commits).
