14 | Description | ||
15 | ----------- | ||
16 | |||
17 | Every ST-Ericsson Ux500 SOC consists of both ABx500 and DBx500 physically, | ||
18 | this is kernel hwmon driver for ABx500. | ||
19 | |||
20 | There are some GPADCs inside ABx500 which are designed for connecting to | ||
21 | thermal sensors, and there is also a thermal sensor inside ABx500 too, which | ||
22 | raises interrupt when critical temperature reached. | ||
23 | |||
24 | This abx500 is a common layer which can monitor all of the sensors, every | ||
25 | specific abx500 chip has its special configurations in its own file, e.g. some | ||
26 | sensors can be configured invisible if they are not available on that chip, and | ||
27 | the corresponding gpadc_addr should be set to 0, thus this sensor won't be | ||
28 | polled. | ||
