Merge tag 'v4.11-rockchip-clk2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next
Pull Rockchip clk updates from Heiko Stuebner:
"Non-critical fix for the pclk_edp divider on rk3399, one new
clock-id and making niu (interconnect) clocks critical on
rk3288, as CLK_IGNORE_UNUSED is not enough to keep them running
all the time when more users access particular clock subtrees."
