[PATCH v2 7/9] ARM: dts: exynos: drop useless 'dma-channels/requests' properties
From: Krzysztof Kozlowski
Date: Sat Apr 30 2022 - 08:19:47 EST
The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless. Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.
