Hi everyone, Here is an attempt at improving the MMC clock support in the Allwinner SoCs. Until now, the MMC clocks were having a custom phase function that was directly setting an obscure value in the right register, because we were not really having any idea of what these values were. Now that we have more informations, we can introduce a common function call to get and set the phase of a particular clock, and use this in both our provider and our client. Another issue we had so far on the A13 was that, out of reset, the PLL6 driving the MMC was running too high to be working. We can solve that by adding two new properties in the DT to setup the rate constraints we might have on a clock.
