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.


Maxime Ripard (5):
  clk: sun6i: Protect CPU clock
  clk: sun6i: Reparent AHB clock on PLL6
  clk: sun6i: Protect SDRAM gating bit
  DMA: sun6i: Add driver for the Allwinner A31 DMA controller
  ARM: sun6i: dt: Add A31 DMA controller to DTSI
