[PATCH 0/7] ARM: berlin: refactor the clock

From: Antoine Tenart
Date: Fri Feb 13 2015 - 11:44:26 EST


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 introducing
a Berlin mfd controller driver. 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 v3.19 and [1].
