2019-02-19dt-bindings: hwmon: (ina3221) Add ti,single-shot propertyNicolin Chen1-0/+10
By default, ina3221, as a hardware monitor, continuously measures the inputs and generates corresponding data. However, for battery powered devices, this mode might be power consuming. This patch adds a "ti,single-shot" property to allow changing the default continuous mode to single-shot operating mode.

2017-12-01hwmon: (jc42) optionally try to disable the SMBUS timeoutPeter Rosin1-0/+4
With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver is not always capable of avoiding the 25-35 ms timeout as specified by the SMBUS protocol. This may cause silent corruption of the last bit of any transfer, e.g. a one is read instead of a zero if the sensor chip times out. This also affects the eeprom half of the nxp-se97 chip, where this silent corruption was originally noticed. Other I2C adapters probably suffer similar issues, e.g. bit-banging comes to mind as risky... The SMBUS register in the nxp chip is not a standard Jedec register, but it is not special to the nxp chips either, at least the atmel chips have the same mechanism. Therefore, do not special case this on the manufacturer, it is opt-in via the device property anyway.
