The only difference between module clocks on different platforms is the width of the mux register bits and the valid values, which are passed in through struct factors_data. The phase clocks parts are identical. This patch generalizes the setup function, so most of the code can be reused when adding sun9i support, which has a wider mux register.

Instead of having three different clocks for the main MMC clock and the two phase sub-clocks, which involved having three different drivers sharing the same register, rework it to have the same single driver registering three different clocks.

With the prcm in sun6i (and some later SoCs) some mod0 clocks are instantiated through the mfd framework, and as such do not work with of_clk_declare, since they do not have registers assigned to them yet at of_clk_declare init time. Silence the error on not finding registers in the of_clk_declare mod0 clk setup method, and also register mod0-clk support as a platform driver to work properly with mfd instantiated mod0 clocks.

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.

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.

The MMC clock we thought we had until now are actually not one but three different clocks. The main one is unchanged, and will have three outputs: - The clock fed into the MMC - a sample and output clocks, to deal with when should we output/sample data to/from the MMC bus The phase control we had are actually controlling the two latter clocks, but the main MMC one is unchanged. We can adjust the phase with a 3 bits value, from 0 to 7, 0 meaning a 180 phase shift, and the other values being the number of periods from the MMC parent clock to outphase the clock of.

Move the MBUS clock to the module clocks file. It's pretty trivial, but still requires to enable the clocks to make sure it won't get disabled. Signed-off-by: NMaxime Ripard <maxime.ripard@free-electrons.com> Acked-by: NHans de Goede <hdegoede@redhat.com>

Since we know have the ability to declare factors clock outside of clk-sunxi, create a new mod0 driver to deal with the mod0 clocks. Signed-off-by: NMaxime Ripard <maxime.ripard@free-electrons.com> Acked-by: NHans de Goede <hdegoede@redhat.com>
