Document the new compatible string "qcom,x1p42100-iris". The x1p42100 SoC integrates the same IRIS video hardware block as SM8550, but represents a distinct hardware instance and therefore uses its own compatible string. The x1p42100 variant includes an additional Bitstream Engine (BSE) clock that is not present on SM8550. This clock is described explicitly in the binding.

On X1P42100 the Iris block has an extra BSE clock. Wire this clock into the power on/off sequence. The BSE clock is used to drive the Bin Stream Engine, which is a sub-block of the video codec hardware responsible for bitstream-level processing. It is required to be enabled separately from the core clock to ensure proper codec operation.

Introduce platform data for X1P42100, derived from SM8550 but using a different clock configuration and a dedicated OPP setup. Link: https://lore.kernel.org/linux-arm-msm/20260401-enable_iris_on_purwa-v4-3-ca784552a3e9@oss.qualcomm.com/ Signed-off-by: Wangao Wang <wangao.wang@oss.qualcomm.com>

This series enables the Iris video codec on purwa, allowing purwa to
use hardware‑accelerated video encoding and decoding.
The Iris codec on purwa is nearly identical to the one on hamoa(X1E),
except that it requires one additional clock and uses a different OPP
table.
Therefore, purwa can reuse the Iris node from hamoa, but the clocks
and OPP table need to be redefined.
All patches have been tested with v4l2-compliance and v4l2-ctl on
purwa. And it does not affect existing targets.
