I didn't get the other 3 patches touching the mmc subsystem, so if and when they get accepted, please ping this devicetree patch.

If you need to resend your series, please make sure you have alphabetically sorted properties -> pinctrl, post-ios-..., pre-power-... and finally reset- gpios. No need to resend just for this though, as I can reorder them myself if needed.
