Merge tag 'sunxi-clk-fixes-for-4.11' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into clk-fixes
Pull Allwinner clock fixes from Maxime Ripard:
A few fixes for a bunch of clocks on a few SoCs. The most important one is
probably one that fixes the NKMP clock frequency calculation and could end
up with clocking the CPU frequency to out of bounds rates.
* tag 'sunxi-clk-fixes-for-4.11' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux:
clk: sunxi-ng: fix recalc_rate formula of NKMP clocks
clk: sunxi-ng: Fix div/mult settings for osc12M on A64
clk: sunxi-ng: sun6i: Fix enable bit offset for hdmi-ddc module clock
clk: sunxi: ccu-sun5i needs nkmp
clk: sunxi-ng: mp: Adjust parent rate for pre-dividers
