* hwmon: (ltc2990) support all measurement modesTom Levens2018-05-211-9/+15
| | | | | | | | | | | | | | | | | | Updated version of the ltc2990 driver which supports all measurement modes (current, voltage, temperature) available in the chip. If devicetree is used, the mode must be specified with the property "lltc,meas-mode". The format and possible values of the property are described in the binding. If devicetree is not used, the mode of the chip will not be configured. Unless the chip is configured by another source, only the internal temperature and supply voltage will be measured.

* hwmon: (core) check parent dev != NULL when chip != NULLLucas Magasweran2018-05-211-1/+2

* hwmon: (lm92) Do not try to detect MAX6635Alvaro G. M2018-03-221-3/+1
| | | | | | | | | | | | Maxim MAX663x family are mostly compatible with LM92, but they lack any identification register. Weakening the detect function would make it prone to false positives, and current one doesn't detect all chips. Therefore, the detect function for max6635 devices is removed in favor of explicit device instatiation.

* hwmon: (pmbus/max31785) Add dual tachometer supportAndrew Jeffery2018-01-021-3/+5
| | | | | | | | | | | | | | | | | | | | | The dual tachometer feature is implemented in hardware with a TACHSEL input to indicate the rotor under measurement, and exposed on the device by extending the READ_FAN_SPEED_1 word with two extra bytes*. The need to read the non-standard four-byte response leads to a cut-down implementation of i2c_smbus_xfer_emulated() included in the driver. Further, to expose the second rotor tachometer value to userspace the values are exposed through virtual pages. We re-route accesses to FAN_CONFIG_1_2 and READ_FAN_SPEED_1 on pages 23-28 (not defined by the hardware) to the same registers on pages 0-5, and with the latter command we extract the value from the second word of the four-byte response. * The documentation recommends the slower rotor be associated with TACHSEL=0, which corresponds to the first word of the response. The TACHSEL=0 measurement is used by the controller's closed-loop fan management to judge target fan rate.

* hwmon: (pmbus/max31785) Add fan controlAndrew Jeffery2018-01-021-0/+7
| | | | | | | | | | | The implementation makes use of the new fan control virtual registers exposed by the pmbus core. It mixes use of the default implementations with some overrides via the read/write handlers to handle FAN_COMMAND_1 on the MAX31785, whose definition breaks the value range into various control bands dependent on RPM or PWM mode.

* pmbus: Add driver for Maxim MAX31785 Intelligent Fan ControllerAndrew Jeffery2017-11-051-0/+51
| | | | | | | | | | | | | | The Maxim MAX31785 is a PMBus device providing closed-loop, multi-channel fan management with temperature and remote voltage sensing. It supports various fan control features, including PWM frequency control, temperature hysteresis, dual tachometer measurements, and fan health monitoring.

* hwmon: (sht15) Root out platform dataLinus Walleij2017-10-291-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | After finding out there are active users of this sensor I noticed: - It has a single PXA27x board file using the platform data - The platform data is only used to carry two GPIO pins, all other fields are unused - The driver does not use GPIO descriptors but the legacy GPIO API I saw we can swiftly fix this by: - Killing off the platform data entirely - Define a GPIO descriptor lookup table in the board file - Use the standard devm_gpiod_get() to grab the GPIO descriptors from either the device tree or the board file table. This compiles, but needs testing.
