Hi,
This patchset adds support for the DMA controller found in the
Allwinner A31 and A23 SoCs.
This has been tested using the newly introduced SPI driver on an A31
EVK. Support for DMA-driven SPI transfers will be the subject of
another patch serie.
Thanks,
Maxime
Changes from v1:
- Removed the clk_put call in the clocks protecting patches
- Minor fixes here and there as suggested by Andy Shevchenko: switch
to dmam_pool_create, switch to dev_dbg instead of pr_debug, etc.
