Hi Bastian, unfortunately with this patch the armaillo800eva no longer boots. I am testing against renesas-next-20130411v2 with the other 6 patches in this series applied. I am using the armadillo800eva defconfig. The boot log is below. I have also tested kzm9g an kzm9g-reference, they seem fine. hermit> tftpboot 10.3.5.147 10.3.5.146 --kernel=armadillo/zImage initializing net-device...OK Client: 10.3.5.147 Server: 10.3.5.146 Region(kernel): armadillo/zImage Filename : armadillo/zImage ......................................................................................................................................................................................................................................................................................................................................................................................................................................................

The part that actually adds the DT info to r8a7740.dtsi. Further we need the GIC to be present in the DT to make things work here (my old patch used the INTCA as interrupt controller reference, but that has gone in the meantime). I want to repost my A1 reference code soon and in there I add the way to set up the GIC via DT. To accelerate things maybe we take 0001-0006 now and postpone 0007 until the GIC is in the DT? I diffed the new patches against the v3 series, and the .dtsi chunk is the only one that didn't make it, so I strongly believe the series is fine now. Thanks, Bastian

Ok, thanks. I'll see about queuing-up 0001-0006 and you can repost 0007 at a later date.
