As I said the SabreSD case seems to be solvable adding support for the
PMIC. I did it for our customer board and it works however it does not
solve the case where the board does not have a PMIC. One of our customer is
in that case and for now I don't know a solution for it.

The PMIC way that has been done in FSL fork is quite ugly as it does not
use the PMIC API but can be used as a base for it.
