From: Linus Torvalds Date: Thu, 16 May 2019 14:56:57 +0000 (-0700) Subject: Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux... X-Git-Tag: v5.15~6345 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a455eda33faafcaac1effb31d682765b14ef868c;p=platform%2Fkernel%2Flinux-starfive.git Merge branch 'linus' of git://git./linux/kernel/git/evalenti/linux-soc-thermal Pull thermal soc updates from Eduardo Valentin: - thermal core has a new devm_* API for registering cooling devices. I took the entire series, that is why you see changes on drivers/hwmon in this pull (Guenter Roeck) - rockchip thermal driver gains support to PX30 SoC (Elaine Zhang) - the generic-adc thermal driver now considers the lookup table DT property as optional (Jean-Francois Dagenais) - Refactoring of tsens thermal driver (Amit Kucheria) - Cleanups on cpu cooling driver (Daniel Lezcano) - broadcom thermal driver dropped support to ACPI (Srinath Mannam) - tegra thermal driver gains support to OC hw throttle and GPU throtle (Wei Ni) - Fixes in several thermal drivers. * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal: (59 commits) hwmon: (pwm-fan) Use devm_thermal_of_cooling_device_register hwmon: (npcm750-pwm-fan) Use devm_thermal_of_cooling_device_register hwmon: (mlxreg-fan) Use devm_thermal_of_cooling_device_register hwmon: (gpio-fan) Use devm_thermal_of_cooling_device_register hwmon: (aspeed-pwm-tacho) Use devm_thermal_of_cooling_device_register thermal: rcar_gen3_thermal: Fix to show correct trip points number thermal: rcar_thermal: update calculation formula for R-Car Gen3 SoCs thermal: cpu_cooling: Actually trace CPU load in thermal_power_cpu_get_power thermal: rockchip: Support the PX30 SoC in thermal driver dt-bindings: rockchip-thermal: Support the PX30 SoC compatible thermal: rockchip: fix up the tsadc pinctrl setting error thermal: broadcom: Remove ACPI support thermal: Fix build error of missing devm_ioremap_resource on UM thermal/drivers/cpu_cooling: Remove pointless field thermal/drivers/cpu_cooling: Add Software Package Data Exchange (SPDX) thermal/drivers/cpu_cooling: Fixup the header and copyright thermal/drivers/cpu_cooling: Remove pointless test in power2state() thermal: rcar_gen3_thermal: disable interrupt in .remove thermal: rcar_gen3_thermal: fix interrupt type thermal: Introduce devm_thermal_of_cooling_device_register ... --- a455eda33faafcaac1effb31d682765b14ef868c diff --cc MAINTAINERS index ee6cf4d,4d08f59..59efb8b --- a/MAINTAINERS +++ b/MAINTAINERS @@@ -742,6 -735,6 +742,12 @@@ F: drivers/tty/serial/altera_jtaguart.
