[PATCH v2 00/11] ARM: berlin: refactor the clock

[Antoine Tenart]

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.

Because the Berlin clock driver was still working with the above
modification, Berlin clock reworks were not included into the previous
series. Also the clock reworks change some of the clock framework
functions, so having a dedicated series helps.

This series aims to convert the Berlin clock driver to use the proper
way of dealing with the chip and system controller on Berlin SoCs. To do
this changes were done in the clk-mux and clk-gate helpers so they can
handle regmaps alongside iomem addresses.

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

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

Thanks!

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