Signed-off-by: Andreas Färber <afaerber@xxxxxxx> --- v2 -> v3: * Fixed uart2 reg offset * Enlarged timer reg size * Added 2 Hz timer interrupts, interrupt-names * Disabled CPUs 1-3 for now (cf. later patches) * Added Cortex-A9 SCU, global timer, TWD timer/wdt nodes * Added HOSC clock for timer v1 -> v2: * Reworded subject * Updated ARCH_OWL to ARCH_ACTIONS (Arnd) * Adopted "actions" vendor prefix * Dropped irq.h include * Added memory@0 node for Guitar SoM * Dropped bogus uart3 clock-frequency * Added device_type for CPU nodes * Fixed UART reg size * Adopted SPDX-License-Identifier (Rob) * Added remaining UART nodes * Added timer node arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/s500-guitar-bb-rev-b.dts | 26 +++++ arch/arm/boot/dts/s500-guitar.dtsi | 24 ++++ arch/arm/boot/dts/s500.dtsi | 170 +++++++++++++++++++++++++++++ 4 files changed, 222 insertions(+) create mode 100644 arch/arm/boot/dts/s500-guitar-bb-rev-b.dts create mode 100644 arch/arm/boot/dts/s500-guitar.dtsi create mode 100644 arch/arm/boot/dts/s500.dtsi diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 0118084..578a20b 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -638,6 +638,8 @@ dtb-$(CONFIG_ARCH_ORION5X) += \ orion5x-maxtor-shared-storage-2.dtb \ orion5x-netgear-wnr854t.dtb \ orion5x-rd88f5182-nas.dtb +dtb-$(CONFIG_ARCH_ACTIONS) += \ + s500-guitar-bb-rev-b.dtb dtb-$(CONFIG_ARCH_PRIMA2) += \ prima2-evb.dtb dtb-$(CONFIG_ARCH_OXNAS) += \ diff --git a/arch/arm/boot/dts/s500-guitar-bb-rev-b.dts b/arch/arm/boot/dts/s500-guitar-bb-rev-b.dts new file mode 100644 index 0000000..834b71d --- /dev/null +++ b/arch/arm/boot/dts/s500-guitar-bb-rev-b.dts @@ -0,0 +1,26 @@ +/* + * Copyright (c) 2016-2017 Andreas Färber + * + * SPDX-License-Identifier: (GPL-2.0+ OR MIT) + */ + +/dts-v1/; + +#include "s500-guitar.dtsi" + +/ { + compatible = "lemaker,guitar-bb-rev-b", "lemaker,guitar", "actions,s500"; + model = "LeMaker Guitar Base Board rev.
