| 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. |
