Subject: [RFC/RFT] ARM: dts: add minimal DT support for Nokia N950 & N9
Date: Wed, 22 May 2013 22:44:04 +0300	[thread overview]
Message-ID: <1369251845-29605-1-git-send-email-aaro.koskinen@iki.fi> (raw)

Add minimal DT support for Nokia N950 & N9. The basic boot works. I can
connect to both devices with USB networking & ssh. dmesg output looks OK.

Functionality compared to the legacy board file:

	- MMC not detected - reason unknown, any tips welcome

	- OneNAND missing completely
