Subject: [PATCH v2 00/10] Marvell Berlin full clock support

This is version 2 of a patch set to bring proper DT based clocks to
Marvell Berlin SoCs.

The overall changes are:

* Dropped of_clk_create_name() helper
Booting into an initramfs rootfs revealed that the unique clock names
created with that helper clash with the way of_clk_get_parent_name()
resolves the clock specifier to get the correct clock name. Anyway,
I still consider the helper a good idea and postpone it to the next
cycle when I have more time to look at the details.

* Added BG2Q core clock driver and dtsi changes
Alexandre just provided them, so I added them to this patch set.

The single patch overview now is:

Patch 1 adds the whole binding documentation for all clock related IP
found on BG2, BG2CD, and BG2Q.

Patch 2 adds corresponding dt-binding includes for the core clock
indices to be used in both DT and the driver.

Patches 3, 4, and 5 add clock drivers for the Audio/Video PLL, simple
PLLs, and complex clock divider cells found on Berlin SoCs. Where
required, currently known differences between BG2/BG2CD and BG2Q are
taken care of.

Patches 6 and 7 add core clock drivers for the remaining clocks of
BG2/BG2CD and BG2Q. The register set dealing with it, is shared among
input and bypass muxes, clock dividers and clock gates.

Patches 8, 9, and 10 finally convert the DT SoC includes for BG2,
BG2CD, and BG2Q to make use of the new clock related DT nodes.

Alexandre Belloni (4):
  clk: berlin: add driver for BG2x simple PLLs
  clk: berlin: add driver for BG2x complex divider cells
  clk: berlin: add core clock driver for BG2Q
  ARM: dts: berlin: convert BG2Q to DT clock nodes

Sebastian Hesselbarth (6):
  dt-binding: clk: add clock binding docs for Marvell Berlin2 SoCs
  clk: berlin: add binding include for BG2/BG2CD clock ids
  clk: berlin: add driver for BG2x audio/video PLL
  clk: berlin: add core clock driver for BG2/BG2CD
  ARM: dts: berlin: convert BG2CD to DT clock nodes
  ARM: dts: berlin: convert BG2 to DT clock nodes
