I tested this series on the FriendlyElec NanoPi R76S.
With the addition of 'cd-gpios = <&gpio0 RK_PA7 GPIO_ACTIVE_LOW>;'
in the board DTS, the µSD hot-plug now works correctly.

However, even with this fix, the NanoPi R76S still suffers from the
constant 400kHz retuning loop when runtime PM is enabled. I will send
a v2 of my driver quirk to address this board-specific instability.
