<title>thermal: devfreq_cooling: Use PM QoS to set frequency limits</title>

<id>urn:sha1:04fa9c804b0ed50a3c6bae1d4b60a2494c81a23f</id>
<content type='text'>
Now that devfreq supports limiting the frequency range of a device
through PM QoS make use of it instead of disabling OPPs that should
not be used.

The switch from disabling OPPs to PM QoS introduces a subtle behavioral
change in case of conflicting requests (min &gt; max): PM QoS gives
precedence to the MIN_FREQUENCY request, while higher OPPs disabled
with dev_pm_opp_disable() would override MIN_FREQUENCY.

<title>trace: thermal: add another parameter 'power' to the tracing function</title>

<id>urn:sha1:771ffa14ead18887bed400c09f4bde5bca5bf342</id>
<content type='text'>
This patch adds another parameter to the trace function:
trace_thermal_power_devfreq_get_power().

In case when we call directly driver's code for the real power,
we do not have static/dynamic_power values. Instead we get total
power in the '*power' value. The 'static_power' and
'dynamic_power' are set to 0.

Therefore, we have to trace that '*power' value in this scenario.

<title>thermal: devfreq_cooling: add new interface for direct power read</title>

<id>urn:sha1:2be83da85a64773efaa407639de81bd1377f880e</id>
<content type='text'>
This patch introduces a new interface for device drivers connected to
devfreq_cooling in the thermal framework: get_real_power().

Some devices have more sophisticated methods (like power counters)
to approximate the actual power that they use.
In the previous implementation we had a pre-calculated power
table which was then scaled by 'utilization'
('busy_time' and 'total_time' taken from devfreq 'last_status').

With this new interface the driver can provide more precise data
regarding actual power to the thermal governor every time the power
budget is calculated. We then use this value and calculate the real
resource utilization scaling factor.

<title>thermal: devfreq: Check OPP for errors</title>

<content type='text'>
It is possible for dev_pm_opp_find_freq_exact() to return errors. It was
all fine earlier as dev_pm_opp_get_voltage() had a check within it to
check for invalid OPPs, but dev_pm_opp_put() doesn't have any similar
checks and the callers need to make sure OPP is valid before calling
them.

Also update the later dev_warn_ratelimited() to not print the error
message as the OPP is guaranteed to be valid now.

There isn't much the user can do on seeing this warning, as the hardware
is actually okay. dev_err suits much better here.

There is no need to check for IS_ERR() as we are looking for a very
particular error value here. Drop the first check.
