Both NVIDIA Tegra20 and Tegra30 SoCs should be blacklisted because CPU
OPPs use supported_hw and thus platdev isn't suitable for these SoCs.
Currently cpufreq-dt driver produces a bit annoying warning splats
during boot because valid OPPs are not found, this will be fixed once
tegra20-cpufreq driver will be update to support cpufreq-dt. The warnings
will also happen on older stable kernels using newer device-trees, thus
this patch should be backported to stable kernels as well.

With the driver installed, we can change the opp-v1 table format
to opp-v2.
In addition, move omap3 from whitelist to blacklist in cpufreq-dt-platdev
in the same patch, because doing either first breaks operation and
may make trouble in bisect.
We also can remove opp-v1 table for omap3-n950-n9 since its 1GHz
capability is now automatically detected.
We also fix a wrong OPP4 voltage for omap3430 which must be
0.6V + 54*12.5mV = 1275mV. Otherwise the twl4030 driver will reject
this OPP.
Note: the high speed OPPs that were not available in the opp-v1 tables
are tagged "turbo-mode;" which means they are not automatically
activated by the govenors or cpu-freq.
To enable you have to write
echo 1 >/sys/devices/system/cpu/cpufreq/boost
Note: to hard disable an OPP in a board.dts file use e.g.
&cpu0_opp_table: {
/delete-node/ opp1g-1000000000; /* do not use */
};
or alternatively:
&cpu0_opp_table: {
opp1g-1000000000 {
status = "disabled"; /* do not use */
};
};

In Certain QCOM SoCs like apq8096 and msm8996 that have KRYO processors,
the CPU frequency subset and voltage value of each OPP varies
based on the silicon variant in use. Qualcomm Process Voltage Scaling Tables
defines the voltage and frequency value based on the msm-id in SMEM
and speedbin blown in the efuse combination.
The qcom-cpufreq-kryo driver reads the msm-id and efuse value from the SoC
to provide the OPP framework with required information.
This is used to determine the voltage and frequency value for each OPP of
operating-points-v2 table when it is parsed by the OPP framework.

Commit edeec420de (cpufreq: dt-platdev: Automatically create cpufreq

create the cpufreq-dt device from their own drivers, after some
dependencies are sorted out.
And for those platforms, both the platform specific driver and the
cpufreq-dt-platdev driver try to create the cpufreq-dt device now.
Fix that by including those platforms in the blacklist. This doesn't include
the TI platforms, for which there is a separate patch.

The initial idea of creating the cpufreq-dt-platdev.c file was to keep a
list of platforms that use the "operating-points" (V1) bindings and
create cpufreq device for them only, as we weren't sure which platforms
would want the device to get created automatically as some had their own
cpufreq drivers as well, or wanted to initialize cpufreq after doing
some stuff from platform code.
But that wasn't the case with platforms using "operating-points-v2"
property. We wanted the device to get created automatically without the
need of adding them to the whitelist. Though, we will still have some
exceptions where we don't want to create the device automatically.
Rename the earlier platform list as *whitelist* and create a new
*blacklist* as well.
The cpufreq-dt device will get created if:
- The platform is there in the whitelist OR
- The platform has "operating-points-v2" property in CPU0's DT node and
isn't part of the blacklist .
