Changes between Initial Version and Version 1 of Ticket #17656, comment 16

initial	v1
1		About EDID, I have a bit of a clue how it works, but I did not get around to actually try to implement it. I think I'd try it first inside the driver, so outside of the common code. I think I saw the newer radeon already supports EDID from such a connection, done inside the driver there as well.

2	2	This dedicated i2c controller is a strange beast I think, not some generic device, but has limitations in transfer size for instance. Also some extra coding has to be done to get that AUX channel going, it may well be powered down by the BIOS as a power-save feature, since it only has to be up for EDID detection. Depending on chipset you (probably) have to poke at different registers to get the power(well) for this going.
3	3	Power saving btw, has no or lo prio for me, I'd just power up for now and leave it that way until a later point in the future if/when this would become important (that would mean the driver has matured a lot I guess ;-)
