Subject[PATCH v17 0/4] Add NVIDIA Tegra GPC-DMA driver
Date
Add support for NVIDIA Tegra general purpose DMA driver for
Tegra186 and Tegra194 platform.

v16 -> v17:
* Updates in terminate_all() and pause().
* Moved DMA busy check to configure_next_sg() from issue_pending()
* shortened variable names -
bytes_requested -> bytes_req; bytes_transferred -> bytes_xfer
* Correction in burst_size calculation
