/*
* Functions used for extracting EDID information from a monitor. These
* functions could easily be modified or made more generic.
*
* Caller should provide a vector of function calls which can
* be called to perform the following low-level functions. See i2c.h
* for details.
*
*
* The function efb_read_edid() will return the edid data as retrieved from
* the monitor. This function will return I2C_OK on success.
*
* Caller should use mutex locking to ensure that two threads do not
* attempt to simultaneously access the monitor. The regular device
* mutex should usually not be used for this purpose if avoidable, as this
* protocol can take a considerable amount of time to execute.
*
* This call will fail on some monitors if sync is not active. In these
* cases, the caller should activate sync and try again.
