stable inclusion from stable-v5.10.127 commit d40514d4403a89e00c17815140b3ec74d8ddd9b6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5XDDK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 048058399f19d43cf21de9f5d36cd8144337d004 upstream.
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.
