cx92755.dtsi describes CX92755 on chip peripherals. cx92755_equinox.dts describes the Equinox evaluation board for the CX92755 SoC. Acked-by: Arnd Bergmann <arnd@xxxxxxxx> Signed-off-by: Baruch Siach <baruch@xxxxxxxxxx> --- This is the only remaining part of the "ARM: Conexant Digicolor CX92755 SoC support" series. See v3 changelog at http://article.gmane.org/gmane.linux.kernel/1865896. v4: * Rename conexant_equinox.dts to cx92755_equinox.dts which is closer to common practice (Olof Johansson) * Add a syscon node; this is now required for the interrupt controller * Decrease the registers range in the interrupt controller node to just the IC registers range. We now use syscon to access the global UC_IRQ_CONTROL register. * Rename the interrupt controller node to "interrupt-controller" as per ePAPR arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/cx92755.dtsi | 113 ++++++++++++++++++++++++++++++++++ arch/arm/boot/dts/cx92755_equinox.dts | 74 ++++++++++++++++++++++ 3 files changed, 188 insertions(+) create mode 100644 arch/arm/boot/dts/cx92755.dtsi create mode 100644 arch/arm/boot/dts/cx92755_equinox.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 91bd5bd62857..71c69a271791 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -75,6 +75,7 @@ dtb-$(CONFIG_ARCH_BRCMSTB) += \ bcm7445-bcm97445svmb.dtb dtb-$(CONFIG_ARCH_DAVINCI) += da850-enbw-cmc.dtb \ da850-evm.dtb +dtb-$(CONFIG_ARCH_DIGICOLOR) += cx92755_equinox.dtb dtb-$(CONFIG_ARCH_EFM32) += efm32gg-dk3750.dtb dtb-$(CONFIG_ARCH_EXYNOS) += exynos3250-monk.dtb \ exynos3250-rinato.dtb \ diff --git a/arch/arm/boot/dts/cx92755.dtsi b/arch/arm/boot/dts/cx92755.dtsi new file mode 100644 index 000000000000..490c08075e67 --- /dev/null +++ b/arch/arm/boot/dts/cx92755.dtsi @@ -0,0 +1,113 @@ +/* + * Device Tree Include file for the Conexant Digicolor CX92755 SoC + * + * Author: Baruch Siach <baruch@xxxxxxxxxx> + * + * Copyright (C) 2014 Paradox Innovation Ltd. + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
