[v11]
 * Split the series into domains

The series adds OPP tables, thermal and CPU definitions in order to support
the CPU frequency scaling on msm8996 CPUs.

1. Add NVMEM node for the speedbin
2. Add definitions for all possible MSM8996 CPU OPPs.
The qcom-cpufreq-kryo driver will select the appropriate subset.

Hello Ilia, Viresh


I tried this patch series (together with you cpu clock driver).

The first problem is that the driver fails to create debugfs entries.

The second problem appears to be that it runs on unlisted frequency.
Is this simply because of missing entries in the opp table?

[    4.538513] cpu cpu1: opp_list_debug_create_link: Failed to create link
[    4.538567] cpu cpu1: _add_opp_dev: Failed to register opp debugfs (-12)

Kind regards,

Hi Niklas,

The frequency list in the DT is correct, but the initial frequency for
the CPUs 0,1 is configured by the XBL, while the CPUs 2,3 stay at XO
rate. Both rates are unlisted in the DT and that's OK.

BR,
Ilia Lin
