[PATCH v7 0/4] cpufreq: qcom-nvmem: add support for ipq806x

[Christian Marangi]

This series originally added support also for ipq807x.
This part was split and is now merged.

This patch was originally dependent of [1] but was later reverted
due to compilation problem. [1] had some changes that weren't related
to the compilation problem and were just a fixup.

This series include these 2 required patches from [1] that are
just cleanup and won't cause any problem.
These 2 patch were already checked and accepted by maintainers.

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.

[PATCH v7 1/4] cpufreq: qcom-nvmem: drop pvs_ver for format a fuses

[Christian Marangi]

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

The fuses used on msm8960 / apq8064 / ipq806x families of devices do not
have the pvs version. Drop this argument from parsing function.

[PATCH v7 2/4] cpufreq: qcom-nvmem: also accept operating-points-v2-krait-cpu

[Christian Marangi]

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

the qcom-cpufreq-nvmem driver attempts to support both Qualcomm Kryo
(newer 64-bit ARMv8 cores) and Krait (older 32-bit ARMv7 cores). It
makes no sense to use 'operating-points-v2-kryo-cpu' compatibility node
for the Krait cores. Add support for 'operating-points-v2-krait-cpu'
compatibility string.

[PATCH v7 3/4] cpufreq: qcom-nvmem: add support for IPQ8064

[Christian Marangi]

IPQ8064 comes in 3 families:
* IPQ8062 up to 1.0GHz
* IPQ8064/IPQ8066/IPQ8068 up to 1.4GHz
* IPQ8065/IPQ8069 up to 1.7Ghz

So, in order to be able to support one OPP table, add support for
IPQ8064 family based of SMEM SoC ID-s and correctly set the version so
opp-supported-hw can be correctly used.

Bit are set with the following logic:
* IPQ8062 BIT 0
* IPQ8064/IPQ8066/IPQ8068 BIT 1
* IPQ8065/IPQ8069 BIT 2

speed is never fused, only pvs values are fused.

IPQ806x SoC doesn't have pvs_version so we drop and we use the new
pattern:
opp-microvolt-speed0-pvs<PSV_VALUE>

Example:
- for ipq8062 psv2
  opp-microvolt-speed0-pvs2 = < 925000 878750 971250>

[PATCH v7 4/4] ARM: dts: qcom: ipq8064: Add CPU OPP table

[Christian Marangi]

Add CPU OPP table for IPQ8062, IPQ8064 and IPQ8065 SoC.
Use opp-supported-hw binding to correctly enable and disable the
frequency as IPQ8062 supports up to 1.0Ghz, IPQ8064 supports up to
1.4GHz with 1.2GHz as an additional frequency and IPQ8065 supports
1.7GHZ but doesn't have 1.2GHZ frequency and has to be disabled.
