Merge tag 'v4.6-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next
Introduction of a factor type and a variant containing a gate to be able to also declare factor clocks in their correct place in the clock tree instead of having to register factor clocks in the init callback separately. And as always some more clock-ids and non-regression fixes for mistakes introduced in past kernel releases.
