| // I2C device drivers may create a /hwmon subdirectory. For example the tmp75 |
| // driver creates a /sys/bus/i2c/devices/<busnum>-<i2caddr>/hwmon |
| // directory. The sensor code relies on the presence of the /hwmon |
| // subdirectory to collect sensor readings. Initialization of this subdir is |
| // not reliable. I2C devices flagged with hasHWMonDir are tested for correct |
| // initialization, and when a failure is detected the device is deleted, and |
| // then recreated. The default is to retry 5 times before moving to the next |
| // device. |
| |
| // Devices such as I2C EEPROMs do not generate this file structure. These |
| // kinds of devices are flagged using the noHWMonDir enumeration. The |
| // expectation is they are created correctly on the first attempt. |
| |
| // This enumeration class exists to reduce copy/paste errors. It is easy to |
| // overlook the trailing parameter in the ExportTemplate structure when it is |
| // a simple boolean. |
