-W83782D, W83783S, W83697HF chips, and the Asus AS99127F chips. We will refer

+This driver implements support for the Winbond W83781D, W83782D, W83783S,
+W83627HF chips, and the Asus AS99127F chips. We will refer to them
+collectively as W8378* chips.
There is quite some difference between these chips, but they are similar
enough that it was sensible to put them together in one driver.

Detection of these chips can sometimes be foiled because they can be in
an internal state that allows no clean access. If you know the address
