This patch adds bindings for i.MX8qm/qxp pixel combiner.
Reviewed-by: Rob Herring robh@kernel.org Signed-off-by: Liu Ying victor.liu@nxp.com --- v3->v4: * No change.
v2->v3: * Add Rob's R-b tag.
v1->v2: * Use graph schema. (Laurent) * Use enum instead of oneOf + const for the reg property of pixel combiner channels. (Rob)
