Please add "if:then:" for this case (need to put all ifs in allOf). I understand that l1tcm is optional *only* on mt8183. Best regards, Krzysztof

The SCP has three memory regions: sram, cfg and l1tcm. While the first two are required, l1tcm is optional. Fix the dt-binding so that it can be omitted and update the description. This gets rid of dtbs_check warnings for devicetrees where the l1tcm reg is missing like mt8183. Signed-off-by: Nícolas F. R. A. Prado <nfraprado@collabora.com> --- Changes in v3: - Made the cfg reg required again. After looking again into the mtk-scp driver, only l1tcm is optional. - Added mention that a dtbs_check warning gets fixed by patch in commit message.
