We generally use 'enable-gpios' or 'powerdown-gpios' even if the h/w 
name is somewhat different.

It is most likely the switch of the mmc regulators from a fixed one
to the AXP regulators.

Please ensure you have the AXP mfd and regulator drivers built-in.
AFAIK the RSB variant of the AXP mfd driver does not support auto
loading of the module.

[linux-sunxi] Latest kernel does not find SD card

2017-11-20 Thread Chris Obbard 
A change between Friday and Sunday evening to sunxi-next Kernel has caused 
my H5-based Orange Pi PC2 to not find the SD card.   Is this a known 
problem?



Sorry for the lack of information; I am not at that terminal.
