| Description |
| ----------- |
| |
| The Texas Instruments OMAP4 family of chips have a bandgap temperature sensor. |
| The temperature sensor feature is used to convert the temperature of the device |
| into a decimal value coded on 10 bits. An internal ADC is used for conversion. |
| The recommended operating temperatures must be in the range -40 degree Celsius |
| to 123 degree celsius for standard conversion. |
| The thresholds are programmable and upon crossing the thresholds an interrupt |
| is generated. The OMAP temperature sensor has a programmable update rate in |
| milli seconds. |
| (Currently the driver programs a default of 2000 milliseconds). |
| |
| The driver provides the common sysfs-interface for temperatures (see |
| Documentation/hwmon/sysfs-interface under Temperatures). |
