The support is limited to whatever devices that are complied in the kernel. At this point we have UARTs handled by "em-uart" and a timer handled by "em-sti". Clocks and SMP are not supported. Signed-off-by: Magnus Damm --- Changes since V2: - converted board-specific emev2-kzm9d.dts into emev2.dtsi Changes since V1: - cleaned up the command line in the dts file - removed call to clock setup code - this should be done through DT - removed map io callback - removed Makefile hacks, people will have to add them by themselves arch/arm/boot/dts/emev2.dtsi | 63 ++++++++++++++++++++++++++++++++++ arch/arm/mach-shmobile/clock-emev2.c | 5 ++ arch/arm/mach-shmobile/setup-emev2.c | 47 ++++++++++++++++++++++++- 3 files changed, 114 insertions(+), 1 deletion(-) --- /dev/null +++ work/arch/arm/boot/dts/emev2.dtsi 2012-05-16 15:01:20.000000000 +0900 @@ -0,0 +1,63 @@ +/* + * Device Tree Source for the EMEV2 SoC + * + * Copyright (C) 2012 Renesas Solutions Corp. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
