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
