Merge tag 'sunxi-clk-for-4.17' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into clk-allwinner

Pull Allwinner clock changes from Maxime Ripard:

Our usual bunch of changes for the next merge window. The most significant
addition is the support of the H6 clock unit. Other than that, there's a
bunch of fixes for the video clocks on the H3 and H5, and some Kconfig
cleanup.

* tag 'sunxi-clk-for-4.17' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux:
  clk: sunxi-ng: add missing hdmi-slow clock for H6 CCU
  clk: sunxi-ng: add support for the Allwinner H6 CCU
  dt-bindings: add device tree binding for Allwinner H6 main CCU
  clk: sunxi-ng: Support fixed post-dividers on NKMP style clocks
  clk: sunxi-ng: h3: h5: export CLK_PLL_VIDEO
  clk: sunxi-ng: h3: h5: Allow some clocks to set parent rate
  clk: sunxi-ng: h3: h5: Add minimal rate for video PLL
  clk: sunxi-ng: Add check for minimal rate to NM PLLs
  clk: sunxi-ng: Use u64 for calculation of nkmp rate
  clk: sunxi-ng: Mask nkmp factors when setting register
  clk: sunxi-ng: remove select on obsolete SUNXI_CCU_X kconfig name
