I dropped from the series the 2 applied patch and added the 2 dependent patch since it seems fixing the problem in the series might take longer times. Can you check?

The first patch of this series was split to a separate series as it doesn't depend on [1] and can be applied right away, [1] introduced some breaking change to function that ipq806x, ipq807x patch was dropped to permit an easier rebase and merge of both. This small series adds support for ipq806x qcom-cpufreq-nvmem driver. Special function are required to make use of the opp-supported-hw binding by hardcoding custom bits based on the qcom SoC ID. The qcom-cpufreq-nvmem driver had recent changes to also improve support for apq8064. Because of this, this series depends on a just merged series. Depends on [1].
