Well not anymore, for RAM constraints as I said. I can still fallback to an older kernel though if I feel like hacking. >> + docg3: flash@0 { >> + compatible = "m-systems,diskonchip-g3"; >> + reg = <0x0 0x2000>; >> + }; > > This currently has no upstream users I can see, so > removing pxa27x would probably mean we should remove > that as well. Yep, this driver was only used on the Mitac MIO A701 (my main board, pxa27x based). >> + panel { >> + compatible = "toshiba,ltm0305a776"; >> + lcd-type = "color-tft"; > > I don't see a driver that matches the compatible string, > does this one actually work? Yes it does. The compatible string doesn't really matter. What is relevant in that part is the "timings" node, which is used by pxafb driver to setup its registers to control the LCD panel. More generally, each and every part of this DT was working 3 years ago. Cheers. -- Robert
