The INA232 is a bidirectional current/power monitor that shares the same I2C register layout as the INA226, but has different electrical characteristics. On the Arduino Monza/Ventuno-Q board, the INA232 is connected on I2C12 at address 0x40 with a 2 mΩ shunt resistor, and is used to monitor the board supply current. Signed-off-by: Loic Poulain --- Changes in v2: - has_update_interval was missing and should be set to true/supported (sashiko/Guenter) - ti,ina232 added to two allOf conditional exclusion blocks. (sashiko) - Fix commit message, it incorrectly mentioned 2Mohm instead of milli-ohm.
