Please use GPIO_ACTIVE_HIGH here.

Please remove the leading 0, so this should be @8.
Please build it with W=1 and make sure it generates no warnings.

I see no SD3 pinctrl entry. If this is related to SD3 card detection,
then it should be part of SD3 pinctrl instead of hog.

Same here.

Does HP mean head phone? If so, this should be part of audio pinctrl
instead of hog.

This property is deprecated as described in
Documentation/devicetree/bindings/mmc/mmc.txt.
Please use 'wakeup-source' instead.
