Merge tag 'v4.6-rockchip-clk2' of... 

Merge tag 'v4.6-rockchip-clk2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next

Pull second batch of rockchip clk updates from Heiko Stuebner:

Inclusion of the rk3368 fractional dividers into our handling scheme,
fixes for missing error-handling in mmc-phase, inverters and cpu-clocks
and some more clock-ids.

* tag 'v4.6-rockchip-clk2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  clk: rockchip: include downstream muxes into fractional dividers on rk3368
  clk: rockchip: set the clock ids for RK3228 HDMI
  clk: rockchip: set the clock ids for RK3228 VOP
  clk: rockchip: add the tsadc clocks found on rk3228 SoCs
  clk: rockchip: add the new clock ids for RK3228 HDMI
  clk: rockchip: add the new clock ids for RK3228 VOP
  clk: rockchip: add id of the tsadc clock found on rk3228 SoCs
  clk: rockchip: fix coding style for clk-cpu.c
  clk: rockchip: don't return NULL when registering mmc branch fails
  clk: rockchip: don't return NULL when registering inverter fails
  clk: rockchip: check grf when waiting pll lock
  clk: rockchip: disable alt_parent clk in err cases when registering cpuclk
