The JPEG encoder and decoder of MT8188 share the same architecture

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,

How this mismatch can result in ABI break?

as MT8188 cannot function correctly under the 32-bit iova
address-space (4GB) configuration.

Do you understand what is an ABI break? This commit is the ABI break.
