Subject: [PATCH 0/5] hwmon: Add TSC1641 I2C power monitor driver

This patch series adds support for the ST Microelectronics TSC1641
I2C power monitor. The TSC1641 provides bus voltage, current, power, 
and temperature measurements via the hwmon subsystem. The driver 
supports optional ALERT pin polarity configuration and exposes the
shunt resistor value and raw shunt voltage via sysfs.

Tested on Raspberry Pi 3B+ with a TSC1641 evaluation board.
