+Description
+-----------
+
+Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically,
+this is kernel hwmon driver for ABx500.
+
+There are some GPADCs inside ABx500 which are designed for connecting to
+thermal sensors, and there is also a thermal sensor inside ABx500 too, which
+raises interrupt when critical temperature reached.
+
+This abx500 is a common layer which can monitor all of the sensors, every
+specific abx500 chip has its special configurations in its own file, e.g. some
+sensors can be configured invisible if they are not available on that chip, and
+the corresponding gpadc_addr should be set to 0, thus this sensor won't be
+polled.

+ If you say yes here you get support for the thermal sensor part
+ of the AB8500 chip. The driver includes thermal management for
+ AB8500 die and two GPADC channels. The GPADC channel are preferably
+ used to access sensors outside the AB8500 chip.
+
+ This driver can also be built as a module. If so, the module
+ will be called abx500-temp.
