[PATCH 00/11] i.MX8MM power domain support

[Lucas Stach]

Hi all,

this adds power domain support for the i.MX8MM to the existing GPCv2
driver. It is not complete yet, as it is still missing the VPU and
display power domains, as those require support for the BLK_CTL
regions of the VPUMIX and DISPLAYMIX domains. A Linux driver for
those regions on the i.MX8MP is currently under development and we
plan to use this as a template for the i.MX8MM when the dust has
settled. The changes in this series have been made with this in
mind, so once the BLK_CTL driver exists it should be a matter of
hooking things together via DT, with no further changes required on
the GPCv2 driver side (famous last words).

Special thanks to Marek Vasut who helped with testing and debugging
of early versions of this code.

Regards,
Lucas
