From bb07a829ec38d2628a7443563fbff5483a3157f2 Mon Sep 17 00:00:00 2001 From: Teresa Remmet Date: Tue, 24 Jan 2017 11:09:34 +0100 Subject: ARM: dts: Add support for phyCORE-AM335x PCM-953 carrier board The phyCORE-AM335x development kit is a combination of the phyCORE-AM335x SoM and a PCM-953 carrier board. The features of the PCM-953 are: * ETH phy on carrier board: 1x RGMII * 1x CAN * Up to 4x UART * USB0 (otg) * USB1 (host) * SD slot * User gpio-keys * User LEDs Signed-off-by: Teresa Remmet Reviewed-by: Wadim Egorov Acked-by: Rob Herring Signed-off-by: Tony Lindgren --- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/am335x-pcm-953.dtsi | 288 +++++++++++++++++++++++++++++++ arch/arm/boot/dts/am335x-phycore-rdk.dts | 27 +++ 3 files changed, 316 insertions(+) create mode 100644 arch/arm/boot/dts/am335x-pcm-953.dtsi create mode 100644 arch/arm/boot/dts/am335x-phycore-rdk.dts (limited to 'arch') diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 6c0a3e3fdf30..1e0bfd1bddfc 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -574,6 +574,7 @@ dtb-$(CONFIG_SOC_AM33XX) += \ am335x-lxm.dtb \ am335x-nano.dtb \ am335x-pepper.dtb \ + am335x-phycore-rdk.dtb \ am335x-shc.dtb \ am335x-sbc-t335.dtb \ am335x-sl50.dtb \ diff --git a/arch/arm/boot/dts/am335x-pcm-953.dtsi b/arch/arm/boot/dts/am335x-pcm-953.dtsi new file mode 100644 index 000000000000..02981eae96b9 --- /dev/null +++ b/arch/arm/boot/dts/am335x-pcm-953.dtsi @@ -0,0 +1,288 @@ +/* + * Copyright (C) 2014-2017 Phytec Messtechnik GmbH + * Author: Wadim Egorov + * Teresa Remmet + * + * This program is free software;
