Merge branches 'clk-mvebu-periph-pm', 'clk-meson', 'clk-allwinner', 'clk-mvebu-dup' and 'clk-davinci' into clk-next

 - S2RAM support for Marvell mvebu periph clks

* clk-mvebu-periph-pm:
  clk: mvebu: armada-37xx-periph: add suspend/resume support
  clk: mvebu: armada-37xx-periph: save the IP base address in the driver data

* clk-meson:
  clk: meson: meson8b: use the regmap in the internal reset controller
  clk: meson: meson8b: register the clock controller early
  clk: meson-axg: pcie: drop the mpll3 clock parent
  clk: meson: axg: round audio system master clocks down
  clk: meson: clk-pll: drop hard-coded rates from pll tables
  clk: meson: clk-pll: remove od parameters
  clk: meson: clk-pll: drop CLK_GET_RATE_NOCACHE where unnecessary
  clk: meson: clk-pll: add enable bit

* clk-allwinner:
  dt-bindings: clock: sun50i-a64-ccu: Add PLL_VIDEO0 macro
  clk: sunxi-ng: a64: Add max. rate constraint to video PLLs
  clk: sunxi-ng: a64: Add minimal rate for video PLLs
  clk: sunxi-ng: sun50i: h6: Add 2x fixed post-divider to MMC module clocks
  clk: sunxi-ng: a83t: Add max. rate constraint to video PLLs
  clk: sunxi-ng: nkmp: Add constraint for maximum rate
  clk: sunxi-ng: r40: Add max. rate constraint to video PLLs
  clk: sunxi-ng: h3/h5: Add max. rate constraint to pll-video
  clk: sunxi-ng: Add maximum rate constraint to NM PLLs
  clk: sunxi-ng: h6: fix PWM gate/reset offset
  clk: sunxi-ng: h6: fix bus clocks' divider position

* clk-mvebu-dup:
  clk: mvebu: ap806: Remove superfluous of_clk_add_provider

* clk-davinci:
  clk: davinci: kill davinci_clk_reset_assert/deassert()
