Subject: [PATCH v2 0/3] i.MX91/93 BLK-CTRL improvements

Hi,

there were several approaches to bring the sub-devices population
mainline [1,2] but non of them made it upstream. Both approaches were
part of either the i.MX93 LVDS or MIPI-CSI enablement.

This small patchset decouples the blk-ctrl changes which allows the
MIPI-CSI and LVDS patchstack to be rebased ontop of this patchset.

Before adding the sub-device supprt, I converted the driver to devm_*
only API.

Regards,
  Marco
