/sys/devices/platform/omapfb/panel/backlight_level and blanking is in omapfb.
> Specifically management of Nokia proprietary chips (Retu, Tahvo) are done in userspace (bme,dsme,?) with kernel driver that mainly allows you to write specific hardware registers from userspace (without documenting those registers of course).
retu-rtc (rtc), tahvo-usb (usb on 770), retu-wdt (watchdog), retu-pwrbutton (guess). All in functional drivers, not just "read/write to registers" as you claim.
bme (battery charging) is unfortunately implemented in software. In the easiest case, you can just ignore it as you would ignore a laptops hardware based charging code.
