docs: hwmon: Add an index file and rename docs to *.rst
Now that all files were converted to ReST format, rename them
and add an index.

The INA219 monitors both shunt drop and supply voltage, with -programmable conversion times and filtering. - -The INA220 is a high or low side current shunt and power monitor with an I2C -interface. The INA220 monitors both shunt drop and supply voltage. - -The INA226 is a current shunt and power monitor with an I2C interface. -The INA226 monitors both a shunt voltage drop and bus supply voltage. - -INA230 and INA231 are high or low side current shunt and power monitors -with an I2C interface. The chips monitor both a shunt voltage drop and -bus supply voltage. - -The shunt value in micro-ohms can be set via platform data or device tree at -compile-time or via the shunt_resistor attribute in sysfs at run-time. Please -refer to the Documentation/devicetree/bindings/hwmon/ina2xx.txt for bindings -if the device tree is used. - -Additionally ina226 supports update_interval attribute as described in -Documentation/hwmon/sysfs-interface. Internally the interval is the sum of -bus and shunt voltage conversion times multiplied by the averaging rate. We -don't touch the conversion times and only modify the number of averages. The -lower limit of the update_interval is 2 ms, the upper limit is 2253 ms. -The actual programmed interval may vary from the desired value. - -General sysfs entries ---------------------- - -======================= =============================== -in0_input Shunt voltage(mV) channel -in1_input Bus voltage(mV) channel -curr1_input Current(mA) measurement channel -power1_input Power(uW) measurement channel -shunt_resistor Shunt resistance(uOhm) channel -======================= =============================== - -Sysfs entries for ina226, ina230 and ina231 only ------------------------------------------------- - -======================= ==================================================== -update_interval data conversion time; affects number of samples used - to average results for shunt and bus voltages. -======================= ==================================================== |
