Subject: [PATCH 04/10] dt-bindings: media: nxp,imx8mq-vpu: Support split G1 and G2 nodes with vpu-blk-ctrl
The G1 and G2 are separate decoder blocks that are enabled by the
vpu-blk-ctrl power-domain controller, which now has a proper driver.
Update the bindings to support separate nodes for the G1 and G2
decoders using the proper driver or the older unified node with
the legacy controls.
To be compatible with older DT the driver, mark certain items as
deprecated and retain the backwards compatible example.
