[PATCH v3 1/5] dt-bindings: media: qcom,sm8550-iris: Add X1P42100 compatible

From: Wangao Wang

Date: Thu Mar 19 2026 - 05:51:10 EST

Document the new compatible string "qcom,x1p42100-iris".

The hardware shares the same IP block and binding as SM8550, but is
described by a separate compatible string due to differences in the
clock topology.

In particular, x1p42100 adds an additional clock for the Bitstream
Engine (BSE), which is not present on SM8550. This clock requires
explicit enable/disable handling and frequency configuration, so it
cannot fall back to sm8550.
