Subject: Add support for 11mV ADC
X-Git-Tag: v1.0~34
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=44b36fe7323a19e37a0889511f84892244ad6283;p=groeck-it87

Add support for 11mV ADC

The ADC LSB on some newer chips such as IT8613E and IT8625E is
officially 11mV, not 10.9mV. Add support for it.
