2018-05-04superio/ite/common: Add options to enable beepsVagiz Trakhanov
Add device tree options to enable beeps when exceeding temperature, voltage, and fan limits. As of this commit, setting voltage and fan limits is not implemented.

2017-10-22superio/ite/common: Make PECI a thermal modeVagiz Trakhanov
Instead of setting "peci_tmpin" in the devicetree, THERMAL_PECI is now a mode of TMPIN like THERMAL_RESISTOR and THERMAL_DIODE. Since the logic to set temperature offsets and limits is in the function that sets thermal modes, it makes sense to treat PECI as yet another mode. As of this commit, there are no boards that actually use peci_tmpin from ite/common. There are three boards that have a similar device tree option, but those boards use it8772f, which implements all superio functions on its own. The first user will probably be Gigabyte GA-Z77-DS3H.

2017-10-22superio/ite/common: Add temperature limitsVagiz Trakhanov
Add devicetree options to set temperature limits that are used to alarm user when temperature exceeds defined values. Audio alerts by superio are not implemented yet, but since limits are visible to userland, some software might use them as is. For instance, lm-sensors displays "ALERT" when temperature exceeds limits.

2017-10-22superio/ite/common: Add temperature offsetVagiz Trakhanov
Add a devicetree option to set temperature adjustment registers required for thermal diode sensors and PECI. However, this commit does not have the code needed to make PECI interface actually use these registers. It only applies to diodes. As a temporary workaround, one can set both THERMAL_DIODE and peci_tmpin to the same TMPIN, e.g. TMPIN3.mode="THERMAL_DIODE" and peci_tmpin="3". PECI, apparently, takes precedence over diode, so the adjustment register will be set and PECI activated. Or simply use the followup patch, which makes THERMAL_PECI a mode like THERMAL_DIODE. I don't have hardware to test THERMAL_DIODE mode, but in case of PECI, without this patch I had about -60°C on idle. Now, with offset 97, which was taken from vendor bios, PECI readings became reasonable 35°C. TEST=Set a temperature offset, then ensure that the value you set is reflected in /sys/class/hwmon/hwmon*/temp[1-3]_offset Change-Id: Ibce6809ca86b6c7c0c696676e309665fc57965d4 Signed-off-by: Vagiz Tarkhanov <rakkin@autistici.org> Reviewed-on: https://review.coreboot.org/21843 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>
2016-11-17sio/ite/common: Add generic environment-controller driverNico Huber
The environment-controller entity is shared by many ITE super-i/o chips. There are some differences between the chips, though. To cover that, the super-i/o chip should select Kconfig options of this driver accordingly. The current implementation isn't exhaustive: It covers only those parts that are connected on boards I could test, plus those that are currently used by the IT8772F. The latter could be ported to use this driver if somebody minds to test it.
