[PATCH v2 00/13] i.MX8MM power domain support

Hi all,

this is the second revision of the patchset to add power domain control
for the i.MX8MM SoC to the GPCv2 driver. For now I've dropped all
support (both DT binding and code) for the power domains that contain
a blk-ctl. Support for those is still under development and will probably
require some more discussions to get things right. However the cut-down
functionality provided by this series is already a big step forward, as
it allows to use USB controllers and GPUs on the i.MX8MM, without the
need to statically turn on the respective power domains before jumping
into Linux.

Regards,
Lucas
