[PATCH 0/3] ARM: berlin: add cpufreq support for the BG2Q

Hi,

This series adds the cpufreq support to the Berlin BG2Q SoC only, as I
told this couldn't be done for BG2 and BG2CD.

First, the cpuclk clock is added to the Berlin 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, when using a BG2Q.

I also added the OPP table definition in the BG2Q device tree. Some
bootloaders may update this table when booting. Mine doesn't.

Tested on a BG2Q DMP.

Thanks,

Antoine
