Fixes for clk drivers:

Browse Source 
- Mark the DDR bus clk critical in the SpaceMiT driver so that
    boot doesn't fail
  - Fix boot on Mobile EyeQ by creating the auxiliary device for
    the ethernet PHY
  - Plug an OF node leak in Rockchip rk808 clk driver

Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk driver fixes from Stephen Boyd:

 - Mark the DDR bus clk critical in the SpaceMiT driver so that
   boot doesn't fail

 - Fix boot on Mobile EyeQ by creating the auxiliary device for
   the ethernet PHY

 - Plug an OF node leak in Rockchip rk808 clk driver

* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
  clk: rk808: fix OF node reference imbalance
  MAINTAINERS: add myself as a reviewer for the clk subsystem
  reset: eyeq: drop device_set_of_node_from_dev() done by parent
  clk: eyeq: add EyeQ5 children auxiliary device for generic PHYs
  clk: eyeq: use the auxiliary device creation helper
  clk: spacemit: k3: mark top_dclk as CLK_IS_CRITICAL
