Subject: [PATCH 00/11] Add throttler driver for non-thermal throttling
Date: Fri, 25 May 2018 13:30:32 -0700 [thread overview]
Message-ID: <20180525203043.249193-1-mka@chromium.org> (raw)
This series adds the throttler driver, for non-thermal throttling of
CPUs and devfreq devices. A use case for non-thermal throttling could
be the detection of a high battery discharge voltage, close to the
over-current protection (OCP) limit of the battery.
To support throttling of devfreq devices the series introduces the
concept of a devfreq policy and the DEVFREQ_ADJUST notifier (similar
to CPUFREQ_ADJUST). Further it includes some related devfreq bugfixes
and improvements that change some of the code that is also touched
by the policy changes.
Matthias Kaehlcke (11):
PM / devfreq: Init user limits from OPP limits, not viceversa
PM / devfreq: Fix handling of min/max_freq == 0
PM / devfreq: Remove check for df->max_freq == 0 from governors
PM / devfreq: Remove redundant frequency adjustment from governors
PM / devfreq: governors: Return device frequency limits instead of
user limits
PM / devfreq: Add struct devfreq_policy
PM / devfreg: Add support policy notifiers
PM / devfreq: Make update_devfreq() public
misc: throttler: Add core support for non-thermal throttling
dt-bindings: misc: add bindings for throttler
misc/throttler: Add Chrome OS EC throttler
