Merge tag 'v4.17-rockchip-clk-1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull Rockchip clk driver updates from Heiko Stuebner:

The rk3328 got the most love this time, preparing it for supplying actual
display output in the future and actually protecting all necessary clocks.
The rk3399 simply got a special 1.6GHz rate that is going to be needed
for a board and the core code got a fix to actually free allocated memory
in error case as well as making sure the clock-phases don't return bad
values and stay the same on rate changes.
