[RFC PATCH 0/7] DMA: Add support for Tegra210 ADMA

[Jon Hunter <jonathanh@nvidia.com>]

Add support for Tegra210 Audio DMA (ADMA) controller. This driver is based
upon the existing Tegra20-APB DMA driver and a lot of the core code has
been re-used.

This is currently being distributed as an RFC to get feedback on the
approach and although this has been compile and boot tested, it still
needs further functional testing to ensure it is working well.

This series is based upon the Tegra-APB clean-up series [0].
