From 03393e8fe651aaf8824c519effbb51bf460ca57f Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Mon, 8 Jul 2013 15:00:30 +0900 Subject: [PATCH] ARM: shmobile: KZM9D DT reference implementation Add a DT reference implementation for the KZM9D board. Only DT devices are used in this case. UART, STI, GPIO and SMP / GIC are all provided by emev2.dtsi. There is still a board specific C file used for enabling legacy SH clocks. This file will be removed after we have moved over to common clocks.
