Subject: [PATCH 2/2] dma: tegra: add support for Tegra114 SoC
Date: Sun, 6 Jan 2013 21:52:03 +0530	[thread overview]
Message-ID: <1357489323-21359-3-git-send-email-ldewangan@nvidia.com> (raw)
In-Reply-To: <1357489323-21359-1-git-send-email-ldewangan@nvidia.com>

NVIDIA's Tegra114 has APB DMA controller which has 32 dma channels
and support support channel wise pause control.

Add support for Tegra114 which uses the channel wise pause control
hardware feature.
