I think Kathiravan only wanted to make sure you have the latest bootloader. Looking at the documentation, I don't see a 1.2 GHz frequency level for this platform. Konrad

Or perhaps, if there's a cpufreq driver (I don't know), check syfs Konrad

The final version of IPQ6000 (SoC id: IPQ6000, SBL version: BOOT.XF.0.3-00086-IPQ60xxLZB-1) has a max design frequency of 1.2GHz, so add this CPU frequency. Signed-off-by: Chukun Pan <amadeus@jmu.edu.cn> --- arch/arm64/boot/dts/qcom/ipq6018.dtsi | 7 +++++++ 1 file changed, 7 insertions(+)
