From ed520c90b3c0453e687404c6028366fdb593d35e Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 11 Nov 2013 13:04:19 -0700 Subject: ARM: tegra: document use of standard DMA DT bindings Update all the Tegra DT bindings to require the standard dmas/dma-names properties rather than non-standard nvidia,dma-request-selector property. This is a DT-ABI-incompatible change. It is the second of two changes required for me to consider the Tegra DT bindings as stable, the other being the previous conversion to the common reset bindings.
