	Before this commit sunxi_factors_register uses of_iomap(node, 0) to get the clk registers. The sun6i prcm has factor clocks, for which we want to use sunxi_factors_register, but of_iomap(node, 0) does not work for the prcm factor clocks, because the prcm uses the mfd framework, so the registers are not part of the dt-node, instead they are added to the platform_device, as platform_device resources. This commit makes getting the registers the callers duty, so that sunxi_factors_register can be used with mfd instantiated platform device too. While at it also add error checking to the of_iomap calls. This commit also drops the __init function from sunxi_factors_register since platform driver probe functions are not __init.

2014-10-21	clk: sunxi: make factors clock mux mask configurable	Chen-Yu Tsai
	Some of the factors-style clocks on the A80 have different widths for the mux values in the registers. Add a .muxmask field to clk_factors_config to make it configurable. Passing a bitmask instead of a width parameter will allow reuse in case we support table-based muxes in the future.

2014-09-27	clk: sunxi: Add sun8i MBUS clock support	Chen-Yu Tsai
	The MBUS clock on sun8i is slightly different from the old mod0 clocks. The divider is 3 bits wider, while also needing a divider table for the higher 4 values, which all set the same divider.
