+MXS LRADC driver:
+This is a classic MFD device as it combines the following subdevices
+ - touchscreen controller (input subsystem related device)
+ - general purpose ADC channels
+ - battery voltage monitor (power subsystem related device)
+ - die temperature monitor (thermal management)
+
+At least the battery voltage and die temperature feature is required in-kernel
+by a driver of the SoC's battery charging unit to avoid any damage to the
+silicon and the battery.
