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 This follows the same pattern as other MediaTek dt-bindings such as mediatek,jpeg-encoder.yaml which uses conditional schemas to support different numbers of iommus per device variant.
