Merge tag 'v5.3-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-rockchip

Pull Rockchip clk driver updates from Heiko Stuebner:

 - New clock-ids+exports for two clocks
 - Cleanup for some boilerplate code for clocks we cannot really control
   from the kernel, but want to define separately to match the
   hardware-description (watchdog in secure-grf)
 - Improvement in mmc phase calculation and cleanup of some rate defintions

* tag 'v5.3-rockchip-clk1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  clk: rockchip: export HDMIPHY clock on rk3228
