This series adds support for the thermal sensors included in the MT8173 SoC. Currently only basic temperature reading is supported without any interrupt support. The cpufreq driver for MT8173 is currently under review, so there's no real cooling device available in mainline. Until this is available the thermal driver can be tested with the following dts snippet. It creates a fake gpio fan and a fake trip point which is so low that it can easily be reached with a "cat /dev/zero > /dev/null" on the command line. Please review and let me know what's missing to be included in mainline. changes since v8: - Add commit description to binding patch - rebase on v4.3-rc2 changes since v7: - re-add some used defines removed in v5 - Use MT8173_THERMAL_ZONE_* defines as array indices in static initializers changes since v6: - remove dot in Hanyi Wus name changes since v5: - update copyright - remove unused defines Changes since v4: - give calibration constants more meaningful names (offset, slope) - Use define instead of 0x00c for register access. Changes since v3: - add include/dt-bindings/thermal/mt8173.h for to be able to use sensor names in dts files - fix disabling wrong clock in error path - remove now unused reset-names property from binding document - rename MT8173_NUM_BANKS -> MT8173_NUM_ZONES - rename MT8173_NUM_SENSING_POINTS -> MT8173_NUM_SENSORS_PER_ZONE - rename struct thermal_zone_device *tz -> struct thermal_zone_device *tzd Changes since v2: - sort #includes alphabetically - Add prefix to register defines - drop some members from struct mtk_thermal - simplify raw_to_mcelsius() - add and use more register bit defines - use device_reset() instead of devm_reset_control_get()/reset_control_reset() - misc other stuff Changes since v1: - Use "mediatek," prefix for custom properties - Drop "thermal: consistently use int for temperatures" dependency Sascha fan: gpio_fan { compatible = "gpio-fan"; gpios = <&pio 24 0>; gpio-fan,speed-map = <0 0 4500 1>; #cooling-cells = <2>; }; thermal-zones { cpu_thermal: cpu_thermal { polling-delay-passive = <1000>; /* milliseconds */ polling-delay = <1000>; /* milliseconds */ thermal-sensors = <&thermal 0>; trips { cpu_passive: cpu_passive { temperature = <47000>; /* millicelsius */ hysteresis = <2000>; /* millicelsius */ type = "passive"; }; cpu_crit { temperature = <90000>; /* millicelsius */ hysteresis = <2000>; /* millicelsius */ type = "critical"; }; }; cooling-maps { map0 { trip = <&cpu_passive>; cooling-device = <&fan THERMAL_NO_LIMIT THERMAL_NO_LIMIT>; }; }; }; }; -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABCAAGBQJWAqrzAAoJEPFlmONMx+ezud4QAK3BODYyBYKDPHRF3M6bwcRR Hc5gO9RuA3asA9eyxS+BCIyo9kuJW1Usb1xAE/YL8ryrXlMHMAGBxJH6jnlkuDTS hNZRXdjIfCSLypWOxOLotDuH8RlRQVW4faNHjGYFxflXSL3YNGQlNPjxS2LLAKdU flLSvwg9aWvtdeIwOyIL/tWbpMgF3sluLIz1K2iElqGKDFSDzwBfYEMlf27d6CKw B3PoqDI0rRR6iDiMBoZFJLYzjyyNSKz9Xqqe9y6osOfPnlC7SRmwbBQ19df/Sqxl +Cd4VsuWedqDmP5WD1MCr5SzYqocUnM54t7aarz5TmVf1Ehd3Z+hBW8ItGJsFPDp Itn75HHiIDxm2GrIIkVs82dr3dUpw3v1vThEke3JqfrOvOi2H0bZ2C5jXCqbFr6M bLKVADmyNDHfP/av+v224zMffmJVqRIedfnBKMV6nDLbTzzjlKVf2n1KeBKjwntS PfEY/E4Qg/PM95E/G1qZCuInAN7w53dNZCGMnm+KCNVAcdkMsEwpNWT1lf8+18ng brXWYXcDCniwr1Ye31NuakGdkWLzSolbpmWS5ValUtA/K9flfZBcnqJ5obF8ooD1 cMnyq4FMpYozhgRYoPVD3pooIBl+yqKNmNtphBftyozZKgPfdOjhPkoCx0hlpBuH 270RN+jva0dOJWk+FXGR =bcx6 -----END PGP SIGNATURE----- commit de42d22304311e6d5d711b85e66a281fe1035ba2 Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue May 12 09:22:29 2015 +0200 ARM64: dts: mt8173: Add thermal/auxadc device nodes Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reviewed-by: Daniel Kurtz <djkurtz@chromium.org>
