2015-08-09hwmon: (it87) Add support for IT8732FJustin Maggard1-7/+36
Add support for the IT8732F. This chip is pretty similar to IT8721F, with the main difference being that the ADC LSB is 10.9 mV instead of 12 mV. Signed-off-by: Justin Maggard <jmaggard@netgear.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2015-04-05hwmon: (it87) Add support for IT8620EGuenter Roeck1-1/+42
IT8620E is mostly compatible to IT7828F. Add generic support for it. IT8620E supports up to 6 fan tachometers and 6 pwm controls. Support for the 6th tachometer and for the additional pwm controls are addded in separate patches. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-04-05hwmon: (it87) Add support for IT8790EGuenter Roeck1-1/+13
IT8790E is a super-IO chip with three fan tachometers. It is mostly compatible to IT8728F, but only supports three fan tachometers instead of five. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-04-05hwmon: (it87) Introduce feature flag to reflect internal in7 sensorGuenter Roeck1-11/+16
On some chips, in7 is always an internal voltage sensor. Introduce feature flag to reflect this condition to simplify adding support for new chips. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-04-05hwmon: (it87) Introduce configuration field for chip suffixGuenter Roeck1-3/+17
ITE chips may have 'E', 'F', or both 'E' and 'F' suffixes. Introduce suffic configuration to the it87_devices structure to simplify adding new chips. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-04-05hwmon: (it87) Fix PWM frequency display for chips with newer PWM controlGuenter Roeck1-9/+25
On chips with newer PWM control, the PWM frequency divider is 256 instead of 128. Since the base PWM frequency remained the same, the actual PWM frequency is half of what it used to be with the older PWM control mechanism.

2015-03-30hwmon: (it87) Fix pwm sysfs attribute removalGuenter Roeck1-1/+1
Detection if a pwm channel is supported was wrong on removal, causing the code to try removing non-existing sysfs attributes. That didn't matter much because sysfs attribute removal of non-existing files fails silently, and because the wrong evaluation always returned false, but should nevertheless be fixed.

2015-03-09hwmon: (it87) No need to skip fan4 for IT8603Guenter Roeck1-4/+0
IT8603 only supports three fans, so it is not necessary to skip fan4. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2015-03-09hwmon: (it87) Add support for IT8781FGuenter Roeck1-8/+24
IT8781F is mostly compatible to IT8782F. Major difference is that it only supports four instead of six UART channels, and therefore does not share the uart6 pins. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

Extend support for reporting and selecting PECI temperature sensors to IT8718, IT8720, IT8782, and IT8783.

IT8721 and IT8728 support Intel PECI temperature reporting. Each sensor can be programmed to display the temperature reported on the PECI interface.

2012-12-20hwmon: (it87) Replace macro defining tempX_type sensors with direct definitionsGuenter Roeck1-10/+11
The macro name show_sensor_offset is confusing since it related to the sensor type, not an offset - even more so when we introduce offset attributes later on. Replace it with direct definitions, and replace the show_sensor/set_sensor function names with show_temp_type/set_temp_type. This also resolves a checkpatch error.
