Subject: [PATCH v2 1/4] arm64: dts: mt8188: update JPEG encoder/decoder compatible
Date: Wed, 24 Dec 2025 11:17:18 +0800 [thread overview]
Message-ID: <20251224031721.9942-2-jianhua.lin@mediatek.com> (raw)
In-Reply-To: <20251224031721.9942-1-jianhua.lin@mediatek.com>
The JPEG encoder and decoder of MT8188 share the same architecture
and features as those of MT8189, both use a 34-bit iova
address-space (16GB) and a single clock configuration.
Previously, MT8188 was incorrectly defined alongside SoCs with 32-bit
iova address-space (4GB), such as "mediatek,mt2701-jpgdec" and
"mediatek,mtk-jpgenc". This mismatch results in an ABI break,
as MT8188 cannot function correctly under the 32-bit iova
address-space (4GB) configuration.
Therefore, MT8188 needs to inherit from MT8189.
Update "mediatek,mtk-jpgenc" to "mediatek,mt8189-jpgenc",
update "mediatek,mt2701-jpgdec" to "mediatek,mt8189-jpgdec".
