[v3,0/4] imx8mp: Add media block control

Message

Hello,

This patch series adds support for the MEDIA_BLK_CTRL of the i.MX8MP to
the imx8m-blk-ctrl driver, and integrates it in the i.MX8MP device tree.

The patches depend on v2 of the series "soc: imx: gpcv2: add PGC
control register indirection" from Lucas Stach [1]. For testing
convenience, a branch that includes the dependency, based on v5.17, is
available at [2].

The series starts with DT bindings (1/4) and driver support (2/4),
followed by addition of the MEDIAMIX power domains to the GPC DT node
(3/4) and finally the new DT node for the MEDIA_BLK_CTRL.

Changes since v2 are listed in changelogs in the individual patches.

The patches have been tested with the ISI and ISP on the i.MX8MP. The
ISI driver is still under development [3], and will be posted in the not
too distant future. ISP support is in a dirty prototype state and will
require more work.
