Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fixes from Stephen Boyd:
"Fixes to the Allwinner and Renesas clk drivers:
- Do the math properly in Allwinner's ccu_mp_recalc_rate() so clk
rates aren't bogus
- Fix a clock domain regression on Renesas R-Car M1A, R-Car H1,
and RZ/A1 by registering the domain after the pmdomain bus is
registered instead of before"

clk: sunxi-ng: mp: Fix dual-divider clock rate readback
clk: renesas: mstp: Add genpd OF provider at postcore_initcall()
