PM / devfreq: Register devfreq as a cooling device on demand

2021-03-09T06:40:16Z

Currently the default behavior is to manually having the devfreq backend to register themselves as a devfreq cooling device. Instead of adding the code in the drivers for the thermal cooling device registering, let's provide a flag in the devfreq's profile to tell the common devfreq code to register the newly created devfreq as a cooling device.

PM / devfreq: Cache OPP table reference in devfreq

2021-02-04T11:06:28Z

The OPP table can be used often in devfreq. Trying to get it each time can be expensive, so cache it in the devfreq struct. Signed-off-by: Saravana Kannan Acked-by: MyungJoo Ham Acked-by: Chanwoo Choi Signed-off-by: Hsin-Yi Wang [ Viresh: Added a blank line ] Signed-off-by: Viresh Kumar

PM / devfreq: Remove redundant governor_name from struct devfreq

2020-10-26T02:50:51Z

The devfreq structure instance contains the governor_name and a governor instance. When need to show the governor name, better to use the name of devfreq_governor structure. So, governor_name variable in struct devfreq is a redundant and unneeded variable. Remove the redundant governor_name of struct devfreq and then use the name of devfreq_governor instance.

PM / devfreq: remove a duplicated kernel-doc markup

2020-10-16T05:28:20Z

The update_devfreq() is also documented at devfreq.c, which has a more complete note. So, drop the duplicated markup, in order to avoid this warning: .../Documentation/driver-api/device_link.rst: WARNING: Duplicate C declaration, also defined in 'driver-api/infrastructure'. Declaration is 'device_link_state'. (and to cause a problem with cross-references to it) Signed-off-by: Mauro Carvalho Chehab

PM / devfreq: Change prototype of devfreq_get_devfreq_by_phandle function

2020-09-29T08:50:10Z

Previously, devfreq core support 'devfreq' property in order to get the devfreq device by phandle. But, 'devfreq' property name is not proper on devicetree binding because this name doesn't mean the any h/w attribute. The devfreq core hand over the right to decide the property name for getting the devfreq device on devicetree. Each devfreq driver will decide the property name on devicetree binding and pass the their own property name to devfreq_get_devfreq_by_phandle function.

PM / devfreq: Add devfreq_get_devfreq_by_node function

2020-09-29T08:50:09Z

Split off part of devfreq_get_devfreq_by_phandle into a separate function. This allows callers to fetch devfreq instances by enumerating devicetree instead of explicit phandles.

PM / devfreq: Add support delayed timer for polling mode

2020-07-30T08:22:57Z

Until now, the devfreq driver using polling mode like simple_ondemand governor have used only deferrable timer for reducing the redundant power consumption. It reduces the CPU wake-up from idle due to polling mode which check the status of Non-CPU device. But, it has a problem for Non-CPU device like DMC device with DMA operation. Some Non-CPU device need to do monitor continuously regardless of CPU state in order to decide the proper next status of Non-CPU device. So, add support the delayed timer for polling mode to support the repetitive monitoring. The devfreq driver and user can select the kind of timer on either deferrable and delayed timer. For example, change the timer type of DMC device based on Exynos5422-based Odroid-XU3 as following: - If want to use deferrable timer as following: echo deferrable > /sys/class/devfreq/10c20000.memory-controller/timer - If want to use delayed timer as following: echo delayed > /sys/class/devfreq/10c20000.memory-controller/timer Reviewed-by: Bartlomiej Zolnierkiewicz Reviewed-by: Lukasz Luba Signed-off-by: Chanwoo Choi
