From mboxrd@z Thu Jan 1 00:00:00 1970 From: marc_gonzalez@sigmadesigns.com (Marc Gonzalez) Date: Tue, 20 Oct 2015 18:35:18 +0200 Subject: [PATCH v5] arm-soc: Add support for Sigma Designs Tango4 platforms In-Reply-To: <56250FAC.2010800@sigmadesigns.com> References: <56250FAC.2010800@sigmadesigns.com> Message-ID: <56266D46.5080809@sigmadesigns.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Support Tango4 platforms (single and dual core SoCs) built around the ARM Cortex-A9 MPCore. Tango4 is not to be confused with Tango3, which was built around the MIPS 74kf. Signed-off-by: Marc Gonzalez --- Changes in v5 drop mac-address property from eth0 node tentatively add pmu node (not looking good) hw perfevents: failed to probe PMU! hw perfevents: failed to register PMU devices! Changes in v4 add memory node, cpus node, l2cc node rewrite clkgen node, as requested by clk maintainers not sure about pmu node --- arch/arm/Kconfig | 2 + arch/arm/Makefile | 1 + arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/tango4-vantage-1172.dts | 18 ++++ arch/arm/boot/dts/tango4.dtsi | 140 ++++++++++++++++++++++++++++++ arch/arm/mach-tangox/Kconfig | 12 +++ arch/arm/mach-tangox/Makefile | 1 + arch/arm/mach-tangox/setup.c | 7 ++ 8 files changed, 183 insertions(+) create mode 100644 arch/arm/boot/dts/tango4-vantage-1172.dts create mode 100644 arch/arm/boot/dts/tango4.dtsi create mode 100644 arch/arm/mach-tangox/Kconfig create mode 100644 arch/arm/mach-tangox/Makefile create mode 100644 arch/arm/mach-tangox/setup.c diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 774dc59650c5..d8f0c31f521f 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -934,6 +934,8 @@ source "arch/arm/mach-sunxi/Kconfig" source "arch/arm/mach-prima2/Kconfig" +source "arch/arm/mach-tangox/Kconfig" + source "arch/arm/mach-tegra/Kconfig" source "arch/arm/mach-u300/Kconfig" diff --git a/arch/arm/Makefile b/arch/arm/Makefile index 7451b447cc2d..7fcb4c63cdf7 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -203,6 +203,7 @@ machine-$(CONFIG_ARCH_SOCFPGA) += socfpga machine-$(CONFIG_ARCH_STI) += sti machine-$(CONFIG_ARCH_STM32) += stm32 machine-$(CONFIG_ARCH_SUNXI) += sunxi +machine-$(CONFIG_ARCH_TANGOX) += tangox machine-$(CONFIG_ARCH_TEGRA) += tegra machine-$(CONFIG_ARCH_U300) += u300 machine-$(CONFIG_ARCH_U8500) += ux500 diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 246473a244f6..2499295051d5 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -605,6 +605,8 @@ dtb-$(CONFIG_MACH_SUN8I) += \ dtb-$(CONFIG_MACH_SUN9I) += \ sun9i-a80-optimus.dtb \ sun9i-a80-cubieboard4.dtb +dtb-$(CONFIG_ARCH_TANGOX) += \ + tango4-vantage-1172.dtb dtb-$(CONFIG_ARCH_TEGRA_2x_SOC) += \ tegra20-harmony.dtb \ tegra20-iris-512.dtb \ diff --git a/arch/arm/boot/dts/tango4-vantage-1172.dts b/arch/arm/boot/dts/tango4-vantage-1172.dts new file mode 100644 index 000000000000..00c9d7e69f80 --- /dev/null +++ b/arch/arm/boot/dts/tango4-vantage-1172.dts @@ -0,0 +1,18 @@ +/dts-v1/;
