X-Git-Tag: next-20140106~108^2~60 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f63e9e0a5eb57ed4d9db54631345d782864ad730;p=karo-tx-linux.git ARM: mxs: Add support for the eukrea-cpuimx28. The following devices/functionalities were tested: * Main UART. * Ethernet0. * Ethernet1. * SD. * USB host. * USB otg. * Display(and its backlight). * Touchscreen. * Audio. * nand. * i2c and the pcf8563 device. * The gpio buttons. * The gpio leds. * Watchdog Cc: Rob Herring Cc: Pawel Moll Cc: Mark Rutland Cc: Stephen Warren Cc: Ian Campbell Cc: devicetree@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Signed-off-by: Eric Bénard Signed-off-by: Denis Carikli Signed-off-by: Shawn Guo --- diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index b14bb117fc3a..dec6e93b656d 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -178,6 +178,8 @@ dtb-$(CONFIG_ARCH_MXS) += imx23-evk.dtb \ imx28-cfa10057.dtb \ imx28-cfa10058.dtb \ imx28-duckbill.dtb \ + imx28-eukrea-mbmx283lc.dtb \ + imx28-eukrea-mbmx287lc.dtb \ imx28-evk.dtb \ imx28-m28cu3.dtb \ imx28-m28evk.dtb \ diff --git a/arch/arm/boot/dts/imx28-eukrea-mbmx283lc.dts b/arch/arm/boot/dts/imx28-eukrea-mbmx283lc.dts new file mode 100644 index 000000000000..7c1572c5a4fb --- /dev/null +++ b/arch/arm/boot/dts/imx28-eukrea-mbmx283lc.dts @@ -0,0 +1,71 @@ +/* + * Copyright 2013 Eukréa Electromatique + * Copyright 2013 Eukréa Electromatique + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
