Merge tag 'sunxi-clocks-for-3.20' of... 

Merge tag 'sunxi-clocks-for-3.20' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into clk-next

Allwinner clock changes for 3.20

The set of clock changes for the 3.20 merge window, with mostly:
  - Some PLL fixes for the A80 and A31
  - The MMC custom phase functions are removed, and moved over to the generic
    phase API.
  - Add the A80 MMC clocks

Some DT changes slipped here as well, to preserve bisectability.

is the normal PLL6 output, or "pll6". The second output is rate doubled

PLL6, or "pll6x2".



The "allwinner,*-mmc-clk" clocks have three different outputs: the

main clock, with the ID 0, and the output and sample clocks, with the

IDs 1 and 2, respectively.



The "allwinner,sun9i-a80-mmc-config-clk" clock has one clock/reset output

per mmc controller. The number of outputs is determined by the size of

the address block, which is related to the overall mmc block.
