[PATCH v3 0/5] media: iris: add support for purwa platform

[Wangao Wang]

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.

The result of v4l2-compliance on purwa:
v4l2-compliance 1.31.0-5379, 64 bits, 64-bit time_t
v4l2-compliance SHA: 14c988631ad4 2025-11-11 11:19:35
