[PATCH v4 2/6] media: dt-bindings: qcom-kaanapali-iris: Add kaanapali video codec binding

From: Vikash Garodia

Date: Thu Oct 01 2026 - 11:57:07 EST

Kaanapali SOC brings in the new generation of video IP i.e iris4. When
compared to previous generation, iris3x, it has,
- separate power domains for stream and pixel processing hardware blocks
(bse and vpp).
- additional power domain for apv codec.
- power domains for individual pipes (VPPx).
- different clocks and reset lines.

Update maxitems constraints for clocks, power-domains, and non-pixel
IOMMUs in the common venus schema to accommodate additional bindings in
kaanapali. Kaanapali platform-specific schema defines fixed constraints
for these properties, so the common schema now serves as an upper bound.
As a result, add explicit maxitems constraints for the non-pixel IOMMUs
in the qcom,sm8550-iris and qcom,sm8750-iris schemas to preserve their
respective fixed constraints.
