/*
* Note that DDC1 does not define any method for returning blocks beyond
* the first. DDC2 does, but the original implementation would only ever
* read the first block. If you want to read and parse all blocks, use
* xf86DoEEDID().
* A note on terminology. DDC1 is the original dumb serial protocol, and
* can only do up to 128 bytes of EDID. DDC2 is I2C-encapsulated and
* introduces extension blocks. EDID is the old display identification
* block, DisplayID is the new one.
