Add LMh nodes for cpu cluster0 and cpu cluster1. Also add interrupt support in cpufreq node to capture the LMh interrupt and let the scheduler know of the max frequency throttling. Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org> --- v1->v2: - Dropped dt property qcom,support-lmh as per Bjorn's review comments. - Changed lmh compatible from generic to platform specific. - Introduced properties specifying arm, low and high temp thresholds for LMh as per Daniel's suggestion. arch/arm64/boot/dts/qcom/sdm845.dtsi | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) -- 2.25.1
