Subject: [PATCH v4 0/2] hwmon: Add TSC1641 I2C power monitor driver
Date: Wed, 5 Nov 2025 12:14:04 -0800 [thread overview]
Message-ID: <20251105201406.1210856-1-igor@reznichenko.net> (raw)
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.
v3: https://lore.kernel.org/linux-hwmon/20251104003320.1120514-1-igor@reznichenko.net/
Changes in v4:
- Updated devicetree binding example
- Removed unnecessary check for !current_lsb
- Added clamping to current val
- No extra calls to validate_shunt()
