Like in H3, A64 SID controller doesn't return correct data
when using direct access. It appears that on A64, SID needs
8 bytes of word_size.
Workaround is to enable read by registers.

If I remove "always-on" the board still will work, since dcdc1 is tied to
mmc0.
vmmc-supply = <®_dcdc1>;
We assume this voltage will be always present and there are some pullups that
are tied to it (on i2c0 and i2c1 bus). In this case should I remove "always-
on" from the regulator node?

Hi Olliver,
Why are you using nRST signal?
What I mean is this pin is inactive on this eMMC chip. To use the signal
byte 162 of ECSD registers should be written.
On my board, this "reset" signal causes eMMC not to work.
Best regards,
Stefan Mavrodiev
