Merge tag 'v4.14-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next

Pull Rockchip clk driver updates from Heiko Stuebner:

The biggest change is fixing the jitter on the fractional clock-type
Rockchip socs experience with the default approximation. For that we
introduce the ability to override it with a clock-specific approximation
and use that to create the needed rate settings as described in the
Rockchip soc manuals (same for all Rockchip socs).

Apart from that we have support for the rk3126 clock controller
which is similar to the rk3128 with some minimal differences
and a lot of improvements and fixes for the rv1108 clock controller
(missing clocks, some clock-ids, naming fixes, register fixes).
