hwmon: (pmbus/xdpe12284) fix typo in compatible strings

2020-02-12T20:43:01+00:00

Make sure that the driver compatible strings matches the binding by removing the space between the manufacturer and model.

hwmon: (pmbus/ltc2978) Fix PMBus polling of MFR_COMMON definitions.

2020-02-10T02:41:08+00:00

Change 21537dc driver PMBus polling of MFR_COMMON from bits 5/4 to bits 6/5. This fixs a LTC297X family bug where polling always returns not busy even when the part is busy. This fixes a LTC388X and LTM467X bug where polling used PEND and NOT_IN_TRANS, and BUSY was not polled, which can lead to NACKing of commands. LTC388X and LTM467X modules now poll BUSY and PEND, increasing reliability by eliminating NACKing of commands.

hwmon: (pmbus) Add support for Infineon Multi-phase xdpe122 family controllers

2020-01-23T21:15:10+00:00

Add support for devices XDPE12254, XDPE12284. All these device support two pages. The below lists of VOUT_MODE command readout with their related VID protocols, Digital to Analog Converter steps, supported by these devices: VR12.0 mode, 5-mV DAC - 0x01; VR12.5 mode, 10-mV DAC - 0x02; IMVP9 mode, 5-mV DAC - 0x03; AMD mode 6.25mV - 0x10.

hwmon: (pmbus/tps53679) Extend device list supported by driver

2020-01-23T21:15:10+00:00

Extends driver with support of the additional devices: Texas Instruments Dual channel DCAP+ multiphase controllers: TPS53688. Extend Kconfig with added device. Signed-off-by: Vadim Pasternak Link: https://lore.kernel.org/r/20200113150841.17670-4-vadimp@mellanox.com Signed-off-by: Guenter Roeck

hwmon: (pmbus/core) Add support for Intel IMVP9 and AMD 6.25mV modes

Extend "vrm_version" with the type for Intel IMVP9 and AMD 6.25mV VID modes. Add calculation for those types. Signed-off-by: Vadim Pasternak Link: https://lore.kernel.org/r/20200113150841.17670-3-vadimp@mellanox.com Signed-off-by: Guenter Roeck

hwmon: (pmbus/core) Add support for vid mode detection per page bases

2020-01-23T21:15:10+00:00

Add support for VID protocol detection per page bases, instead of detecting it based on "PMBU_VOUT" readout from page 0 for all the pages supported by particular device. The reason that some devices allows to configure different VID modes per page within the same device. Patch modifies the field "vrm_version" within the structure "pmbus_driver_info" to be per page array.

hwmon: (pmbus/ibm-cffps) Prevent writing on_off_config with bad data

2020-01-23T21:15:10+00:00

If the user write parameters resulted in no bytes being written to the temporary buffer, then ON_OFF_CONFIG will be written with uninitialized data. Prevent this by bailing out in this case.
