hwmon: (pmbus) Add support for Texas Instruments tps53679 device
The below lists of VOUT_MODE command readout with their related VID protocols, Digital to Analog Converter steps, supported by the device: VR12.0 mode, 5-mV DAC - 0x21 VR12.5 mode, 10-mV DAC - 0x22 VR13.0 mode, 10-mV DAC - 0x24 IMVP8 mode, 5-mV DAC - 0x25 VR13.0 mode, 5-mV DAC - 0x27 Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
