Subject: [GIT PULL] Thermal control updates for v6.3-rc1
Hi Linus,
I'm sending this ahead of time, because I will be traveling next week
and I don't want to delay the integration of the changes below just
because of my absence.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
thermal-6.3-rc1
with top-most commit 6828e402d06f7c574430b61c05db784cd847b19f
thermal/drivers/st: Remove syscfg based driver
on top of commit acd7e9ee57c880b99671dd99680cb707b7b5b0ee
thermal: intel: int340x: Add locking to int340x_thermal_get_trip_type()
to receive thermal control updates for 6.3-rc1.
The majority of changes here are related to the general switch-over to
using arrays of generic trip point structures registered along with a
thermal zone instead of trip point callbacks (this has been done mostly
by Daniel Lezcano with some help from yours truly on the Intel drivers
front).
Apart from that and the related reorganization of code, there are some
enhancements of the existing driver and a new Mediatek Low Voltage
Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
rework so it will use the generic idle_inject facility for CPU idle time
injection going forward and it will take additional module parameters
for specifying the subset of CPUs to be affected by it (work done by
Srinivas Pandruvada).
Also included are assorted fixes and a whole bunch of cleanups.
Specifics:
- Rework a large bunch of drivers to use the generic thermal trip
structure and use the opportunity to do more cleanups by removing
unused functions from the OF code (Daniel Lezcano).
- Remove core header inclusion from drivers (Daniel Lezcano).
- Fix some locking issues related to the generic thermal trip rework
(Johan Hovold).
- Fix a crash when requesting the critical temperature on tegra, which
is related to the generic trip point work (Jon Hunter).
- Clean up thermal device unregistration code (Viresh Kumar).
- Fix and clean up thermal control core initialization error code
paths (Daniel Lezcano).
- Relocate the trip points handling code into a separate file (Daniel
Lezcano).
- Make the thermal core fail registration of thermal zones and cooling
devices if the thermal class has not been registered (Rafael Wysocki).
- Add trip point initialization helper functions for ACPI-defined trip
points and modify two thermal drivers to use them (Rafael Wysocki,
Daniel Lezcano).
- Make the core thermal control code use sysfs_emit_at() instead of
scnprintf() where applicable (ye xingchen).
- Consolidate code accessing the Intel TCC (Thermal Control Circuitry)
MSRs by introducing library functions for that and making the
TCC-related code in thermal drivers use them (Zhang Rui).
- Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
changes (Zhang Rui).
- Address an "unsigned expression compared with zero" warning in the
intel_soc_dts_iosf thermal driver (Yang Li).
- Update comments regarding two functions in the Intel Menlow thermal
driver (Deming Wang).
- Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
driver (ye xingchen).
- Make the intel_pch thermal driver support the Wellsburg PCH (Tim
Zimmermann).
- Modify the intel_pch and processor_thermal_device_pci thermal drivers
use generic trip point tables instead of thermal zone trip point
callbacks (Daniel Lezcano).
- Add production mode attribute sysfs attribute to the int340x thermal
driver (Srinivas Pandruvada).
- Rework dynamic trip point updates handling and locking in the int340x
thermal driver (Rafael Wysocki).
- Make the int340x thermal driver use a generic trip points table
instead of thermal zone trip point callbacks (Rafael Wysocki, Daniel
Lezcano).
- Clean up and improve the int340x thermal driver (Rafael Wysocki).
- Simplify and clean up the intel_pch thermal driver (Rafael Wysocki).
- Fix the Intel powerclamp thermal driver and make it use the common
idle injection framework (Srinivas Pandruvada).
- Add two module parameters, cpumask and max_idle, to the Intel powerclamp
thermal driver to allow it to affect only a specific subset of CPUs
instead of all of them (Srinivas Pandruvada).
- Make the Intel quark_dts thermal driver Use generic trip point
objects instead of its own trip point representation (Daniel
Lezcano).
- Add toctree entry for thermal documents and fix two issues in the
Intel powerclamp driver documentation (Bagas Sanjaya).
- Use strscpy() instead of strncpy() in the thermal core (Xu Panda).
- Fix thermal_sampling_exit() (Vincent Guittot).
- Add Mediatek Low Voltage Thermal Sensor (LVTS) driver (Balsam Chihi).
- Add r8a779g0 RCar support to the rcar_gen3 thermal driver (Geert
Uytterhoeven).
- Fix useless call to set_trips() when resuming in the rcar_gen3
thermal control driver and add interrupt support detection at init
time to it (Niklas Söderlund).
- Fix memory corruption in the hi3660 thermal driver (Yongqin Liu).
- Fix include path for libnl3 in pkg-config file for libthermal (Vibhav
Pant).
- Remove syscfg-based driver for st as the platform is not supported
any more (Alain Volmat).
Thanks!
