[PATCH 05/31] ARM: tegra: update DT files to add DMA properties

Stephen Warren swarren at wwwdotorg.org
Fri Nov 15 15:54:00 EST 2013


From: Stephen Warren <swarren at nvidia.com>

This patch switches the Tegra DT files to use the standard DMA DT bindings
rather than custom properties. Note that the legacy properties are not yet
removed; the drivers must be updated to use the new properties first.
