sunxi: clock: H6/H616: Fix PLL clock factor encodings Most clock factors and dividers in the H6 PLLs use a "+1 encoding", which we were missing on two occasions. This fixes the MMC clock setup on the H6, which could be slightly off due to the wrong parent frequency: mmc 2 set mod-clk req 52000000 parent 1176000000 n 2 m 12 rate 49000000 Also the CPU frequency (PLL1) was a tad too high before. For PLL5 (DRAM) we already accounted for this +1, but in the DRAM code itself, not in the bit field macro. Move this there to be aligned with what the other SoCs and other PLLs do.

mmc: sunxi: Fix MMC clock parent selection Most Allwinner SoCs which use the so called "new timing mode" in their MMC controllers actually use the double-rate PLL6/PERIPH0 clock as their parent input clock. This is interestingly enough compensated by a hidden "by 2" post-divider in the mod clock, so the divider and actual output rate stay the same. Even though for the H6 and H616 (but only for them!) we use the doubled input clock for the divider computation, we never accounted for the implicit post-divider, so the clock was only half the speed on those SoCs. This didn't really matter so far, as our slow MMIO routine limits the transfer speed anyway, but we will fix this soon. Clean up the code around that selection, to always use the normal PLL6 (PERIPH0(1x)) clock as an input. As the rate and divider are the same, that makes no difference. Explain the hardware differences in a comment. Signed-off-by: Andre Przywara <andre.przywara@arm.com>
