[PATCH 0/9] i.MX8MP power-domains part 1 and GPU support

Hi all,

this series starts adding the power-domain control for the i.MX8MP
SoC. The GPCv2 support is complete (at least from going over the RM,
TF-A and experience with other i.MX8M* SoCs), but not all
power-domains are usable right now. Currently only the HSIO
(USB and PCIe) and GPU power domains are enabled.

Other power domains (MEDIA, VPU, HDMI, AUDIO) can be added when the
blk-ctrl driver support for those domains is ready, which is still
work in progress at the moment. As my priorities are shifting to
other things for a while, I wanted to push out the part that is
usable now and enables more functionality on the i.MX8MP.

Regards,
Lucas
