hwmon: (pmbus) Use 64bit math for DIRECT format values

2018-03-01T03:09:46Z

[ Upstream commit bd467e4eababe4c04272c1e646f066db02734c79 ] Power values in the 100s of watt range can easily blow past 32bit math limits when processing everything in microwatts. Use 64bit math instead to avoid these issues on common 32bit ARM BMC platforms.

kconfig: use bool instead of boolean for type definition attributes

2015-01-07T12:08:04Z

Support for keyword 'boolean' will be dropped later on. No functional change. Reference: http://lkml.kernel.org/r/cover.1418003065.git.cj@linux.com Signed-off-by: Christoph Jaeger Signed-off-by: Michal Marek

hwmon: (ltc2978) Add regulator support

2014-12-01T04:13:13Z

Add simple on/off regulator support for ltc2978 and other pmbus parts supported by the ltc2978 driver. Signed-off-by: Alan Tull Cc: Guenter Roeck Cc: Mark Brown Signed-off-by: Guenter Roeck

hwmon: (pmbus) Add regulator support

2014-12-01T04:13:13Z

Add support for simple on/off control of each channel. To add regulator support, the pmbus part driver needs to add regulator_desc information and number of regulators to its pmbus_driver_info struct. regulator_desc can be declared using default macro for a regulator (PMBUS_REGULATOR) that is in pmbus.h The regulator_init_data can be initialized from either platform data or the device tree.

hwmon: (pmbus) add helpers for byte write and read modify write

2014-12-01T04:13:13Z

Add two helper functions: * pmbus_write_byte_data = paged byte write * pmbus_update_byte_data = paged byte read/modify/write Signed-off-by: Alan Tull Cc: Mark Brown Signed-off-by: Guenter Roeck

hwmon: (pmbus) Add tps40422 front-end driver

2014-08-04T14:01:38Z

For TI power management chip TPS40422, READ_TEMPERATURE_2 command is supported on page 1 of the chip, but the original driver(pmbus.c) only tried to detect this command on page 0, this will lead to a result that the temperature sensor in page 1 couldn't be detected. This change is to isolate the tps40422 driver from pmbus.c into a solo front-end driver.

hwmon: (pmbus/ltc2978) Add support for LTM4676

2014-03-20T01:59:40Z

The chip's programming interface is quite similar to LTC3880 and supports the same set of sensors. Reviewed-by: Robert Coulson Signed-off-by: Guenter Roeck

hwmon: (pmbus/ltc2978) Add new chip ID for LTC2974

2014-03-06T05:52:06Z

LTC2974 datasheet revision C lists the chip ID for LTC2974 as 0x0213. Reviewed-by: Robert Coulson Signed-off-by: Guenter Roeck

hwmon: (pmbus) Support per-page exponent in linear mode

2014-02-03T05:21:40Z

Some chips use different exponents for sensors on different pages or rails. Detect and store exponent per page to support this situation. This fixes a problem with wrong voltages seen on UCD90120. Reported-by: Soren Brinkmann Tested-by: Soren Brinkmann Signed-off-by: Guenter Roeck

hwmon: (pmbus/ltc2978): Add support for LTC2978A
