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. Sascha changes since v10: - Some style cleanup - Add comment to make clear why we use the sensors in banks even if we currently only use the maximum of all banks changes since v9: - rebase on v4.3 - Add support for reading the calibration values from nvmem fuses - Only register a single thermal zone instead of four as it seems that's everything needed 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 ------------- 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>; 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 iQIcBAABCAAGBQJWQHCkAAoJEPFlmONMx+ezneEP/265kyAMT71c7/HewE7kA1aZ 3/ah5w7gtOjBlY0y3VNaVCs0u0gJEUqa/JFIBRvXm61mNoDt/uKH1hP5IroHVFHa uW9wc1nOgr8G185IZRYszIePwchoKE0lBLTpt1DplK8NwUv6k9NXdAlXlDrLkejQ fDnvGbIq0Ok5OLntjp81hGUxOYcyfoQrqHTLUWohzsovRwVegVOMOh08gwnWNJuI DKMaKlv4XpUiX8roeUEgQdrVnTLsddR85mvPonLcjIwpCMNooLygNKDmlTHf3C4g VFpdoUH04cc1XdxtxJ6oAetCq+/C6z9BA22nVWm+tRecN8VU+ywjB9xo2qUR+xjv aqEhKZMq8eTWNKWYUIhBh/LBPtoqZb5rYoS+Z76xFD/e+/umviscoh/QhavuohvZ bEMGIY4jziUMccFzklzZGyfxPPcVx9yIwB0+q4IgkWxGYznFyXcuNi4+J3xcxtid xYq1B6kcbca7G2UgEtt+JMSl9ukZYSeOAXGgYGQWsP0VyZWohvm+bH7FX455eHyX FLd+b3CpUEyxT3yL7ZpuJeiwzpnpsOgbqSu5Djzd5KpgUNnl4QCRAFAv4L9BqKZM L1ugFAhFJFcBIhjhgthws5WLhAY/hEI2gDaesYq2Wu5GgXiqZNIJyp7D1EA9RRpO RQjaXpX7u47O5HgQpfBA =4rKu -----END PGP SIGNATURE----- commit 53fcb89e372f49218e33889286a1812595e38cf3 Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue May 12 09:22:29 2015 +0200 ARM64: dts: mt8173: Add thermal/auxadc device nodes This adds the thermal controller and auxadc nodes to the Mediatek MT8173 dtsi file.
