Main SCP SRAM memory region (required) 2. SCP L1TCM memory region (optional, for additional memory) Some other MediaTek SoCs only use a single memory region. This patch adds a conditional schema using if/then to allow 1-2 memory regions specifically for mediatek,mt8188-scp and mediatek,mt8188-scp-dual compatibles, while keeping the default maxItems: 1 for other SoCs. Each memory region is documented with descriptions to clarify their purpose, following the pattern used in other bindings.
