Subject: [PATCH 0/2] hwmon: Add JEDEC PMIC50x0 driver for DDR5 PMICs
Date: Wed, 21 Jan 2026 15:19:45 +0000 [thread overview]
Message-ID: <20260121151947.37719-1-almogbs@amazon.com> (raw)
This series adds support for JEDEC PMIC50x0 compliant DDR5 Power
Management ICs. These devices provide comprehensive hardware monitoring
capabilities including voltage, current, power, and temperature
monitoring across multiple channels.
The driver implements:
- Voltage monitoring for 4 channels
- Current monitoring for 4 channels
- Power monitoring for 5 channels (including sum)
- Temperature monitoring
- Error detection and reporting with per-error counters
Tested on TI,TPS53830 DDR5 PMICs at I2C addresses 0x4a and 0x4b.
