The first patch makes all the drivers store their mode in struct thermal_zone_device. Such a move has consequences: driver-specific variables for storing mode are not necessary. Consequently get_mode() methods become obsolete. Then sysfs "mode" attribute stops depending on get_mode() being provided, because it is always provided from now on. The first patch also introduces the initial mode to be optionally passed to thermal_zone_device_register(). Given all the groundwork done in patch 1/2 patch 2/2 becomes very simple. Compared to RFC v3 this series addresses comments from Bartlomiej, thank you Bartlomiej for your review! RFCv3..this PATCH: - export thermal_zone_device_{enable|disable}() for drivers - don't check provided enum values in acpi's thermal_zet_mode() and in int3400_thermal_set_mode() - use thermal_zone_device_enable() in of_thermal instead of open coding it - use thermal_zone_device_{enable|disable}() in hisi_thermal, rockchip_thermal and sprd_thermal - assume THERMAL_DEVICE_ENABLED is thermal_zone_params not provided at tzd's register time - eliminated tzp-s which contain only .initial_mode = THERMAL_DEVICE_ENABLED, - don't set tz->need_update and don't call thermal_zone_device_update() at the end of thermal_zone_device_register() - used .initial_mode in int340x_thermal_zone, x86_pkg_temp_thermal and int3400_thermal Andrzej Pietrasiewicz (2): thermal: core: Let thermal zone device's mode be stored in its struct thermal: core: Stop polling DISABLED thermal devices drivers/acpi/thermal.c | 35 ++-------- .../ethernet/mellanox/mlxsw/core_thermal.c | 42 ------------ drivers/platform/x86/acerhdf.c | 17 +---- drivers/thermal/da9062-thermal.c | 11 ---- drivers/thermal/hisi_thermal.c | 6 +- drivers/thermal/imx_thermal.c | 24 ++----- .../intel/int340x_thermal/int3400_thermal.c | 31 ++------- .../int340x_thermal/int340x_thermal_zone.c | 1 + .../thermal/intel/intel_quark_dts_thermal.c | 22 ++----- drivers/thermal/intel/x86_pkg_temp_thermal.c | 1 + drivers/thermal/of-thermal.c | 24 +------ drivers/thermal/rockchip_thermal.c | 6 +- drivers/thermal/sprd_thermal.c | 6 +- drivers/thermal/thermal_core.c | 65 ++++++++++++++++--- drivers/thermal/thermal_core.h | 3 + drivers/thermal/thermal_sysfs.c | 29 +-------- include/linux/thermal.h | 22 ++++++- 17 files changed, 121 insertions(+), 224 deletions(-) base-commit: 79799562bf087b30d9dd0fddf5bed2d3b038be08 -- 2.17.1
