Hmm. Good point. I was thinking that the driver is only used on OMAP, but of course that's not true, the driver is there for all platforms if the kernel just happens to be compiled with the driver. And it's not just about those drivers you mention. The same issue is there for, say, "ti,tpd12s015". I have an omapdss specific driver for that, but if some other platform uses the same chip, they'll have a driver for it also... Sigh. I wonder how this should be handled... The only solution that comes to my mind is to have all the compatible strings as "ti,...". But that's not correct, as they are not TI components, but some are generic ones and some from another vendor. And even "ti,..." is not good, as there are other TI SoCs with other display drivers. So I'd need to prepend the compatible strings with "omapdss,...", making the hardware components driver specific. The long term plan is to make the drivers generic (or implement the same driver for common display framework). But for now I need to have future proof DT bindings with omapdss specific drivers...
