[PATCH 2/3] mfd: ahc1ec0-hwmon: Add sub-device hwmon for Advantech embedded controller
From: Shihlun Lin
Date: Wed Oct 14 2020 - 04:40:02 EST
This is one of sub-device driver for Advantech embedded controller
AHC1EC0. This driver provides sysfs ABI for Advantech related
applications to monitor the system status.
