So, this will work even though my SD Host controller is: "Compatible
with the SD memory card specification version 3.01", yes?
Does this mean that the compatibility concerns things like physical
connection, and supported speeds whereas things like
"SD_EXT_POWER_OFF_NOTIFY" are solely software features that can
handled by mmc core if sd card firmware supports it?

Best regards
Patryk
