Subject: [PATCH 2/7] ARM: dts: Update edma bindings on dm814x to use edma_xbar
Date: Thu,  3 Dec 2015 17:25:30 -0800	[thread overview]
Message-ID: <1449192335-10137-3-git-send-email-tony@atomide.com> (raw)
In-Reply-To: <1449192335-10137-1-git-send-email-tony@atomide.com>

The edma is the same as on am33xx, except it has four tptc
instances. And we need the edma_xbar for at least mmc3, so
let's use the edma_xbar and the new binding as suggested by
Peter Ujfalusi <peter.ujfalusi@ti.com>.
