It depends entirely on the platform, the interconnect, the panel and the controller. You may have a way of probing it, but even on a PC in a lot of cases the knowledge is actually in the firmware not in the panel itself. In some cases the relationship is even more incestuous (eg look at some of the MIPI drivers). > p.s. linus - this is another example of where the complete total > utter lack of hardware standardisation and of the complete > non-existence of a BIOS in the embedded / ARM world (for very good > technical reasons) makes life continued and absolute hell. ref: > https://lkml.org/lkml/2011/7/1/473 Well really the panel belongs in devicetree. That would I think sort much of the mess out.
