From b98da4db297bad34a5577df36ff4cb2a8fc90923 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 19 May 2013 00:47:39 +0200 Subject: [PATCH] ARM: nomadik: fix IRQ assignment for SMC ethernet The assignment of IRQ for the SMC91x ethernet adapter had two problems making it non-working: - It was not put into the ethernet device node. Let's do this by using the board-specific overlay, so we can make other overlays on other Nomadik boards. - The IRQ number was actually completely wrong, this was the number for NHK8815, not S8815. After this ethernet starts working on the USB S8815.
