This patch updates the MediaTek SCP device tree binding to support
multiple memory regions for MT8188 SoCs, addressing review feedback
from v1.
The MT8188 SCP requires two memory regions (SRAM + L1TCM) while other
MediaTek SoCs use only one. This patch follows the proper pattern of
using conditional schemas with explicit descriptions.
Changes in v2:
- Use conditional schema (if/then in allOf) to restrict multiple
memory regions only to MT8188 variants, keeping maxItems: 1 as
default for other SoCs (addresses Krzysztof's review)
- Add explicit item descriptions for each memory region (Main SRAM
and optional L1TCM) instead of just setting minItems/maxItems
- Apply to both top-level and patternProperties
Based on linux-next, tag: next-20260505
