Since commit 9bcf15f75cac ("iio: adc: axp288: Fix TS-pin handling") we preserve the bias current set by the firmware at boot. This fixes issues we were seeing on various models. Some models like the Nuvision Solo 10 Draw tablet actually need the old hardcoded 80ųA bias current for battery temperature monitoring to work properly. Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table to restore setting the bias current to 80ųA on this model.
