[PATCH v2 1/7] arm64: dts: mediatek: mt6795: Remove deprecated UART DMA property
From: AngeloGioacchino Del Regno
Date: Tue Jul 07 2026 - 11:52:35 EST
Remove the mediatek,dma-33bits property as it is now deprecated
and, while at it, also remove the fallback compatible as it was
not entirely right to use anyway, because this IP is not fully
compatible with the one found in MT6577 and would create more
issues than the ones it could resolve (as in - it's better to
not probe the controller than to probe it and manage it in some
incorrect way).
