Subject: [PATCH v3] drivers: hwmon: max31827: handle vref regulator
Date: Mon, 25 Sep 2023 11:23:33 +0300 [thread overview]
Message-ID: <20230925082334.8310-1-antoniu.miclaus@analog.com> (raw)
Add missing implementation for the max31827 supply regulator.
This is a hardware required property that is not handled.

changes in v3:
- revert also the dev_err_probe output to use "vref" instead of "vdd".
