Subject: Add feature flag indicating that VIN3 is connected to 5V
X-Git-Tag: v1.0~61
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=7e0c08854762f4e5d7f4d77cfbe2d0048080db79;p=groeck-it87

Add feature flag indicating that VIN3 is connected to 5V

On IT8622E and IT8628E, VIN3 is expected to be connected to +5V.
Add feature flag and reflect in input label.
