Documentation/powercap/dtpm: Add documentation for dtpmThe dynamic thermal and power management is a technique to dynamicallyadjust the power consumption of different devices in order to ensure aglobal thermal constraint.An userspace daemon is usually monitoring the temperature and thepower to take immediate action on the device.The DTPM framework provides an unified API to userspace to act on thepower.Document this framework.Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>Reviewed-by: Lukasz Luba <lukasz.luba@arm.com>Signed-off-by: Rafael J.

powercap: Add Power Limit4 supportModern Intel Mobile platforms support power limit4 (PL4), which isthe SoC package level maximum power limit (in Watts). It can be usedto preemptively limits potential SoC power to prevent power spikesfrom tripping the power adapter and battery over-current protection.This patch enables this feature by exposing package level peak powercapping control to userspace via RAPL sysfs interface. With this,application like DTPF can modify PL4 power limit, the similar wayof other package power limit (PL1).As this feature is not tested on previous generations, here it isenabled only for the platform that has been verified to work,for safety concerns.Signed-off-by: Sumeet Pawnikar <sumeet.r.pawnikar@intel.com>Co-developed-by: Zhang Rui <rui.zhang@intel.com>Signed-off-by: Zhang Rui <rui.zhang@intel.com>Reviewed-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>Tested-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>Signed-off-by: Rafael J.

docs: power: convert docs to ReST and rename to *.rstConvert the PM documents to ReST, in order to allow them tobuild with Sphinx.The conversion is actually: - add blank lines and indentation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups.At its new index.rst, let's add a :orphan: while this is not linked tothe main index.rst file, in order to avoid build warnings.Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>Acked-by: Mark Brown <broonie@kernel.org>Acked-by: Srivatsa S.
