Running cpufreq-hw driver on Lenovo Yoga C630 laptop, the following warning messages will be seen. [ 3.415340] cpu cpu4: Voltage update failed freq=2841600 [ 3.418755] cpu cpu4: failed to update OPP for freq=2841600 [ 3.422949] cpu cpu4: Voltage update failed freq=2956800 [ 3.427086] cpu cpu4: failed to update OPP for freq=2956800 This is because the cpufreq-hw lookup table of SDM850 provides these two set-points, but they are missing from OPP table in DT. Let's create sdm850.dtsi to add the OPP for them, so that the warning will be gone.
