touchscreen .dts variants for debian's 3.16 kernel? (Was: Re: [linux-sunxi] Backporting simplefb support to 3.16 kernel)

[Jens Thiele <karme@karme.de>]

would it be possible to add touchscreen .dts variants to the debian
kernel source? the touchscreen variant adds:
+		rtp: rtp@01c25000 {
+			allwinner,ts-attached;
+		};

yes, it is ugly, and afair Hans de Goede proposed a different solution
on linux-sunxi (device tree overlays?) i didn't have time to understand,
yet.

But it would make it simple to support the A13‑LCD7‑TS, A13‑LCD10TS,
LCD‑OLinuXino‑7TS, LCD-OLinuXino-10TS touchscreens. But maybe I miss
something obvious here?

to make it more clear:
