Subject: [PATCH -next 0/2] dmaengine: xilinx_dma: In dma channel probe fix node order dependency
Date: Thu, 30 Jan 2020 18:24:23 +0530	[thread overview]
Message-ID: <1580388865-9960-1-git-send-email-radhey.shyam.pandey@xilinx.com> (raw)

In overlay application[1] we noticed that channel DT nodes are inverted and
as a sideffect of this behaviour the axidmatest client fails.

In general driver should not assume specific DT probe order. So to fix this
failure remove channel node ordering restriction from the xilinx dma driver.
