* hwmon: (it87) Add support for IT8620EGuenter Roeck2015-04-051-3/+10
| | | | | | | | | | | 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>

* hwmon: (jc42) Add support for additional IDT temperature sensorsGuenter Roeck2015-03-091-5/+3Star
| | | | | | | | | | | | | | | | TS3000GB0 has a new device ID (0x2913). Since IDT's datasheets suggest that the upper 8 bit of the device ID reflect the chip ID and the lower 8 bit reflect the version number, modify the code to accept all chips with ID 0x29xx. Also add support for TS3001 and TSE2004. Some of the datasheets for older chips are no longer available from the IDT web site, so replace explicit links in the documentation with a generic note.

| | | | | | | | | | | | | This attribute allows to configure the update interval of ina226. Although the bus and shunt voltage conversion times remain hardcoded to 1.1 ms, we can now modify said interval by changing the averaging rate. While we're at it - add an additional variable to ina2xx_data, which holds the current configuration settings - this way we'll be able to restore the configuration in case of an unexpected chip reset.
