2025-05-02media: iris: add qcs8300 platform dataVikash Garodia
Add platform data for QCS8300, which has different capabilities compared to SM8550. Introduce a QCS8300 header that defines these capabilities.

2025-05-02media: platform: qcom/iris: add sm8650 supportNeil Armstrong
Add support for the SM8650 platform by re-using the SM8550 definitions and using the vpu33 ops. Move the Sm8650 reset tables that differs in a per-SoC platform header, that will contain mode SoC specific data when more codecs are introduced. The SM8650/vpu33 requires more reset lines, but the H.264 decoder capabilities are identical.
