This series updates the mtk,scp dt-binding schema to support MT8188's
requirement for two memory regions while maintaining backward
compatibility for other MediaTek SoCs.
The schema uses a permissive base with restrictive conditionals:
1) Base schema allows all devices minItems: 1, maxItems: 2
2) Non-MT8188 devices (mt8183, mt8186, mt8192, mt8195, mt8195-dual) are
restricted to maxItems: 1, overriding the base
3) MT8188 devices (mt8188, mt8188-dual) set minItems: 1 with item
descriptions, inheriting maxItems: 2 from base, making the second
L1TCM region optional
Changes in v3:
- Removed "Tested on..." line per Krzysztof's feedback (bindings cannot be
tested)
- Added minItems: 1 to MT8188 conditional to make L1TCM region truly optional
- Clarified commit message to specifically reference mediatek,jpeg-encoder.yaml
pattern
- Restructured schema per Conor's feedback: base allows maxItems: 2,
conditionals restrict
- Added explicit restrictions for non-MT8188 devices (maxItems: 1)
- Added technical explanation of the permissive base + restrictive conditionals
pattern
Changes in v2:
- Added conditional schema for MT8188 to allow 1-2 memory regions
- Added descriptions for each memory region
- Did not work: base maxItems: 1 conflicted with conditional trying to allow 2
