Re: [PATCH v2 4/4] media: mediatek: jpeg: add compatible for MT8189 SoC

From: Nicolas Dufresne <hidden>
Date: 2025-12-24 19:34:22
Also in: linux-devicetree, linux-media, linux-mediatek, lkml

Le mercredi 24 décembre 2025 à 11:17 +0800, Jianhua Lin a écrit :
Compared to the previous generation IC, the MT8189 uses 34-bit iova
address-space (16GB) and requires a single clock configuration.
Therefore, add new compatible to support the JPEG encoder and decoder
of MT8189 SoC.

I'll have to wait for some ack on the bindings, which looks otherwise fine to
me. But due to holiday, that might be delayed a little bit.

cheers,
Nicolas
