* docs: hwmon: convert three docs to ReST formatMauro Carvalho Chehab2019-04-234-14/+33
| | | | | | | | | | | | | | | | | | | | | | Those three new drivers were missed on the initial conversion to ReST format. So: - Rename them to .rst; - Add them to the hwmon index.rst index; - add some blank lines at the "Supported systems:" part, in order to allow Sphinx to properly identify new lines, suppressing warnings and avoid it to output some random lines in bold; - When multiple authors are involved, change the authors part to a list, in order to avoid adding blank lines. - adjust the table cells (one of the tables seemed to be assuming that tab is 4 positions instead of 8) and add the table markup. - be sure that the section markups have the same number of characters as the section title.

* hwmon: (ina3221) Add voltage conversion time settingsNicolin Chen2019-04-181-0/+13
| | | | | | | | | | | | | | | | | | | | | The CONFIG register has two 3-bit fields for conversion time settings of Bus-voltage and Shunt-voltage, respectively. The conversion settings, along with averaging mode, allow users to optimize available timing requirement. This patch adds an 'update_interval' sysfs node through the hwmon_chip_info of hwmon core. It reflects a total hardware conversion time: samples * channels * (Bus + Shunt conversion times) Though INA3221 supports different conversion time setups for Bus and Shunt voltages, this patch only adds the support of a unified setting for both conversion times, by dividing the conversion time into two equal values.

* hwmon: (adt7475) document mapping of sysfs entries to inputsChris Packham2018-12-031-0/+12
| | | | | | | | | | | | | | | | | | | | As per the usual standard with hwmon drivers the mapping to sysfs entries follows the register map of the device e.g. in0_input corresponds to the register 0x20, in1_input corresponds to 0x21 etc. Hardware designers tend to work with input pins instead of registers which is where things start to get confusing. A hardware designer might say "the 1.5V rail is connected to the VCCP pin" leaving the software designer none the wiser as to which of the sysfs entries should be associated with the label "1.5V". Try to bridge the gap by documenting the mapping of sysfs entries to the corresponding pins. This should allow someone to create a configuration file or other mapping without needing to dive into the code and ADT datasheets.

* hwmon: (adm1275) Allow setting shunt reg valueKun Yi2018-12-031-0/+3
| | | | | | | | | | | | | | | The ADM series of hotswap controllers support extending the current measurement range by using a sensing resistor value other than the typical 1 mOhm. For example, using a 0.5 mOhm sensing resistor doubles the maximal current can be measured. Current driver assumes a shunt resistor value of 1 mOhm in calculation, meaning for other resistor values, hwmon will report scaled current/power measurements.

* hwmon: (ina3221) Read channel input source info from DTNicolin Chen2018-10-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | An ina3221 chip has three input ports. Each port is used to measure the voltage and current of its input source. The DT binding now has defined bindings for their input sources, so the driver should read these information and handle accordingly. This patch adds a new structure of input source specific information including input source label, shunt resistor value and its connection status. It exposes these labels via in[123]_label sysfs nodes upon available, and also disables those channels where there are no input source being connected. Meanwhile, it also adds in[123]_enable sysfs nodes for users to get control of three channels, and returns -ENODATA code for any sensor read according to hwmon ABI.
