Merge branch 'depends/clk' into next/soc

From Mike Turquette:
* depends/clk:
  clk: Common clocks implementation for Versatile Express
  clk: Versatile Express clock generators ("osc") driver
  CLK: clk-twl6040: Initial clock driver for OMAP4+ McPDM fclk clock
  clk: fix return value check in sirfsoc_of_clk_init()
  clk: fix return value check in of_fixed_clk_setup()
  clk: ux500: Update sdmmc clock to 100MHz for u8500
  clk: ux500: Support prcmu ape opp voltage clock
  mfd: dbx500: Export prmcu_request_ape_opp_100_voltage
  clk: Don't return negative numbers for unsigned values with !clk
  clk: Fix documentation typos
  clk: Document .is_enabled op
  clk: SPEAr: Vco-pll: Fix compilation warning
