Merge branches 'clk-iproc', 'clk-mvebu' and 'clk-qcom-a53' into clk-next

* clk-iproc:
  clk: iproc: Minor tidy up of iproc pll data structures
  clk: iproc: Allow plls to do minor rate changes without reset
  clk: iproc: Fix error in the pll post divider rate calculation
  clk: iproc: Allow iproc pll to runtime calculate vco parameters

* clk-mvebu:
  clk: mvebu: armada-37xx-periph: Use PTR_ERR_OR_ZERO()

* clk-qcom-a53:
  clk: qcom: Add APCS clock controller support
  clk: qcom: Add regmap mux-div clocks support
  clk: qcom: Add A53 PLL support
