[PATCH v3 0/9] ARM: berlin: refactor the clock

[PATCH v3 0/9] ARM: berlin: refactor the clock

[Antoine Tenart]

Hi,

Since v2, this series has changed a lot. We postponed the introduction
of regmap into the Berlin clock driver (and some parts of the clock
framework) to first take care of the Berlin DT reorganisation of the
chip and system controllers.

Marvell Berlin SoCs have a chip control register set providing several
individual registers dealing with various controllers (pinctrl, reset,
clk). This chip controller is described by a single DT node since the
individual registers are spread among the chip control register bank.

Marvell Berlin also have a system control register set providing several
individual registers for pinctrl or adc.

A series was sent[1] to correctly handle these two nodes, by using
simple-mfd. The series converted the existing pin-controller and reset
drivers to take the changes into account.

This series moves the clock DT bindings into their own sub-node of the
chip controller node, and make minor changes into the Berlin clock
driver to take this change into account.

This series has been tested on the Marvell Berlin BG2Q DMP.

This series is based on v4.0-rc1 and [1].

Thanks!

Antoine

Changes since v2:
	- Removed all regmap related changes and kept only minor
	  needed changes in the Berlin clock driver.

Changes since v1:
        - Rebased of top of the new version of [1].
	- Removed now useless chip and system ctrl compatibles.

[PATCH v3 2/9] Documentation: bindings: move the Berlin clock documentation

[Antoine Tenart]

The Berlin clock documentation was part of the Marvell Berlin SoC
documentation because the Berlin clock configuration was inside the
chip controller. With the recent rework of the chip and system
controller handling (now all sub-devices of the soc and system
controller nodes are registred with simple-mfd, and each device has its
own sub-node), the documentation of the Berlin clock driver can be moved
to the generic clock documentation directory.

[PATCH v3 7/9] ARM: berlin: remove useless chip and system ctrl compatibles in BG2

[Antoine Tenart]

Now that the rework to have one sub-node per device in the chip and
system controllers is done, their dedicated compatible can be removed.

Mike, Stephen,

would you mind to give your Acked-by for this patch and let me take
this through Berlin and ARM-SoC tree? The patch only touches berlin-
specific subdirectories in clk/ so there should be no merge issues
expected.
