Subject: ARM: dts: zynq-7000: drop useless 'dma-channels/requests' properties
X-Git-Url: http://git.dujemihanovic.xyz/posts?a=commitdiff_plain;h=89c3a5151c97b48c0246f33213e160c81717dd34;p=u-boot.git

ARM: dts: zynq-7000: drop useless 'dma-channels/requests' properties

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.
