From 2d52ee82b4756d11565e94b8c09e77bb8c036a11 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C3=81lvaro=20Fern=C3=A1ndez=20Rojas?= Date: Sat, 9 Apr 2016 12:57:49 +0200 Subject: [PATCH] MIPS: BMIPS: Improve BCM6368 device tree MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit - Remove unneeded leds0 alias. - Switch to bcm6345-l1-intc interrupt controller. - Use interrupt-controller instead of periph_intc and cpu_intc. - Add uart1 node. - Single ohci and ehci nodes. - Avoid using underscores in node names. - Rename uart aliases to serial. - Remove blank line in cpus node.
