Subject: [PATCH v2 0/2] 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 update interval via sysfs.

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

Changes in v2:
- Fixed devicetree binding name and formatting issues
- Alert limits are handled in a standard way
- Clamped alert limit values, constrained valid shunt values
- Cleaned up includes, fixed various style issues
- Expanded documentation
