Since both > the platform and the drivers get removed, the order should not matter. This part is a bit ... bothering. I at least identified these : > delete mode 100644 drivers/input/touchscreen/wm9705.c > delete mode 100644 drivers/input/touchscreen/wm9712.c > delete mode 100644 drivers/input/touchscreen/wm9713.c > delete mode 100644 drivers/input/touchscreen/wm97xx-core.c > delete mode 100644 drivers/mfd/wm97xx-core.c > delete mode 100644 sound/ac97/bus.c > delete mode 100644 sound/ac97/codec.c > delete mode 100644 sound/ac97/snd_ac97_compat.c For the existing platforms working with devicetree support (mioa701 for example), the wm9713 was properly used, providing both sound support and input touchscreen. So was the a97 part, providing a framework to make the wm9713 work. So I'm wondering how the choice to chop these drivers was done, and it is necessary to remove them. If so, maybe pxa support in the kernel should be removed all together, as people playing with it loose part of the working DT platforms they had. As for the removal of defconfigs and arch-pxa, sure, this was PXA's destiny. Cheers. -- Robert PS: If this mail is sent twice, sorry in advance, my mailer is a bad mood lately.
