Kernel driver e50sn12051
========================
Supported chips:
* Delta E50SN12051
Prefix: 'e50sn12051'
Addresses scanned: -
Datasheet:
Provided by Delta upon request and NDA
Description
-----------
E50SN12051 is a 600W non-isolated 1/8th brick DC-DC power module.
This driver supports the E50SN12051 PMBus compliant monitor device.
The device provides measurements for:
* Input voltage
* Output current
* Output voltage
* Temperature
The driver is based on the PMBus core and exposes standard hwmon
sysfs attributes.
