Subject: [PATCH v3 0/6] ARM: berlin: add cpufreq support

Hi,

This series adds the cpufreq support to the Berlin SoCs, using
cpufreq-dt.

First, the cpuclk clock is added to the BG2Q clock driver. This clock
has a divider fixed to 1, so we use a fixed factor clock here.

Then register a platform device for cpufreq-dt.

I also added the OPP table definition in the BG2Q, BG2 and BG2CD device
trees. When using a BG2Q, some bootloaders may update this table when
booting (mine doesn't).

Tested on a BG2Q DMP.

Thanks,

Antoine

Changes since v2:
	- rebased on top of v4.3-rc1

Changes since v1:
        - added the BG2 and BG2CD support
        - moved MAX_CLKS out of the Berlin clk driver
        - reordered the patches
