hwmon: (adm1275) Add support for ADM1278

2016-03-05T14:36:03+00:00

ADM1278 is mostly compatible to other chips of the same series. Besides the usual difference in coefficients, it supports a temperature sensor, and it can measure both input and output voltage at the same time. Signed-off-by: Guenter Roeck

hwmon: (pmbus) Add client driver for LTC3815

2015-12-18T16:20:59+00:00

LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter. Cc: Michael Jones Signed-off-by: Guenter Roeck

hwmon: (ltc2978) Add support for LTM4675

2015-08-19T16:08:55+00:00

LTM2975 is a dual 9A or single 18A μModule regulator. It is register compatible with LTM4676. Signed-off-by: Guenter Roeck

hwmon: (ltc2978) Add polling for chips requiring it

2015-08-19T16:08:41+00:00

Some of the LTC chips supported by this driver have to be polled to ensure that they are ready to accept commands. Signed-off-by: Michael Jones [Guenter Roeck: simplifications and formatting changes] Signed-off-by: Guenter Roeck

hwmon: (pmbus) Enable PEC if the controller supports it

2015-08-19T16:08:29+00:00

PMBus controllers optionally support PEC. Configure the driver to use it if available to improve operational security. Suggested-by: Michael Jones Signed-off-by: Guenter Roeck

hwmon: (pmbus) Use BIT macro

2015-08-19T16:08:17+00:00

Using the BIT macro makes the code a little easier to read. Signed-off-by: Guenter Roeck

hwmon: (ltc2978) Add support for LTC3886

2015-08-17T23:36:00+00:00

LTC3886 is a is a dual PolyPhase DC/DC synchronous step-down switching regulator controller. It is mostly command compatible to LTC3883, but supports two phases instead of one. Suggested-by: Michael Jones Tested-by: Michael Jones Signed-off-by: Guenter Roeck

hwmon: (ltc2978) Add support for LTC2980 and LTM2987

2015-08-17T23:35:59+00:00

LTC2980 and LTM2987 are command compatible to LTC2977. They consist of two LTC2977 on a single die, and are instantiated as two separate chips, each supporting eight channels. Suggested-by: Michael Jones Tested-by: Michael Jones Signed-off-by: Guenter Roeck

hwmon: (ltc2978) Add missing chip IDs for LTC2978 and LTC3882

2015-08-17T23:35:13+00:00

Add additional chip ID for an older revision of LTC2978, as well as two chip IDs for LTC3882. Turns out the LTC3882 does support the LTC2978_MFR_SPECIAL_ID register, and reading it returns its chip ID, but the register is undocumented.

hwmon: (ltc2978) Use correct ID mask to detect all chips

2015-08-17T23:34:02+00:00

Per information from Linear Technologies, the ID mask is 12 bit for all chips of this series. Use this mask to detect chips to ensure that all chip revisions are detected. Suggested-by: Michael Jones Tested-by: Michael Jones Signed-off-by: Guenter Roeck
