[PATCH v2 0/6] Add Marvell berlin4ct clk support

[Jisheng Zhang]

Add berlin4ct clk driver. The berlin4ct SoC contains:

two kinds of PLL: normal PLL and AVPLL. The normal PLL support is done.
The AVPLL support is in TODO list.

two kinds of clk: normal clk and gate clk. The normal clk supports changing
divider, selecting clock source, disabling/enabling etc. The gate clk only
supports disabling/enabling. Both are supported in this series.

Since v1:
 - rebased on v4.4-rc1
 - refactor out common code from clk-berlin4ct.c
 - s/lock/berlin4ct_gateclk_lock
 - drop WARN_ON for an allocation failure
 - s/kzalloc/kcalloc
 - add necessary handling in error code path, such as free memory, iounmap etc.
 - initialize init.flags
 - drop vcodiv_berlin[] array

  clk: berlin: add common pll driver
  clk: berlin: add common clk driver for newer SoCs
  clk: berlin: add common gateclk driver for newer SoCs
  clk: berlin: add clk support for berlin4ct
  dt-bindings: add binding for marvell berlin4ct SoC
  arm64: dts: berlin4ct: add pll and clock nodes
