Subject: [PATCH v3 0/6] ARM: berlin: add cpufreq support
Date: Thu, 17 Sep 2015 12:14:59 +0200 [thread overview]
Message-ID: <1442484905-15656-1-git-send-email-antoine.tenart@free-electrons.com> (raw)
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
