(However, Only SOC, or SOC and Clocks, or SOC and Clocks and Cpufreq will work) SOC (1/15): Extracts the kryo l2 accessors driver from the QCOM PMU driver Clocks (2/15-9/15): This series adds support for the CPU clocks on msm8996 devices. The driver uses the existing PLL drivers and is required to control the CPU frequency scaling on the MSM8996. Cpufreq (10/15-12/15): The qcom-cpufreq-kryo driver is aimed to support different SOC versions. The driver reads eFuse information and chooses the required OPP subset by passing the OPP supported-hw parameter. Regulators (13/15-15/15): Added SAW regulator support to the SPMI regulator driver. The SAW regulators will be controlled through special CPU registers instead of direct SPMI accesses.
