Subject: dt-bindings: media: qcom,sm8550-iris: Do not reference legacy venus properties
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6d3926a237b68e3bfd3068553e6c3fa3fed1ea1b;p=users%2Fhch%2Fmisc.git

dt-bindings: media: qcom,sm8550-iris: Do not reference legacy venus properties

The Qualcomm SoC Iris video codec is an evolution of previous Venus and
it comes with its own Iris Linux drivers.  These new drivers were
accepted under condition they actually improve state of afairs, instead
of duplicating old, legacy solutions.

Unfortunately binding still references common parts of Venus without
actual need and benefit.  For example Iris does not use fake
"video-firmware" device node (fake because there is no actual device
underlying it and it was added only to work around some Linux issues
with IOMMU mappings).

Stop referencing venus-common schema in the new Qualcomm Iris bindings
and move all necessary properties, except unused "video-firmware" (no
driver usage, no DTS).
