From 988ae9cbf8efbb2050a34e61b5518d93f41cb606 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Fri, 26 Apr 2013 16:55:40 +0000 Subject: at91: upgrade to kernel 3.8.7 and use devicetree This upgrades the AT91 target to 3.8.7, and migrates to device tree. This allows a single kernel to be built for most at91 variants which simplifies things quite a bit. The immediate result is that all subtargets are nuked, and any boards without dts files are no longer supported, though the target now includes more boards than before. The adc driver was also nuked as 3.8.7 includes a new one under the IIO subsystem.
