This version of the patchset does not contain the interrupt router driver anymore (MSCM). The driver has been sent in a seperate patchset with GIC (Cortex-A5) support only: https://lkml.org/lkml/2014/12/16/454 This patchset extends the NVIC driver to support irq domain hierarchy and the MSCM driver to support NVIC as a parent irq controller. I'm happy with the outcome of the MSCM driver, the irq domain hierarchy support has proven to work with GIC and NVIC as intendet. This version also does not add any new architecture or SoC anymore. Instead, it allows to select ARCH_MULTIPLATFORM in the !MMU case and add ARCH_MULTI_V7M as a new CPU choice. This change is based on patches found in Arnd's git tree, however, it tries to allow MULTIPLATFORM with !MMU in a way which should not allow to make other selections than before (except ARCH_MULTI_V7M of course). This makes ARCH_MXC and SOC_VF610 available for the !MMU CPU V7M. With a small change, SOC_VF610 is now useable for the Cortex-M4 CPU too. The patchset has proven to be working on the Cortex-A5 as well as on the Cortex-M4 of the Vybrid SoC. Changes since v1: - Remove MSCM driver - Support irq domain hierarchy with NVIC irq controller - Extend MSCM interrupt router with NVIC as parent in the irq domain hierarchy - Rebased on v3.19-rc1 with MSCM driver - NVIC: Register only the amount of IRQ's which vectors are available for Changes since RFC: - Unified addruart calls for MMU/!MMU - Add MSCM support along with routable IRQ support in NVIC - Rebased on Shawns for-next tree which made some changes obsolete (mainly the Vybrid SoC device tree files in for-next are already prepared for Cortex-M4 support) - Removed SRC_GPR3 hack, this is now part of a mini boot-loader: https://github.com/falstaff84/vf610m4bootldr Arnd Bergmann (1): ARM: efm32: move into multiplatform Stefan Agner (11): genirq: generic chip: support hierarchy domain irqchip: nvic: support hierarchy irq domain irqchip: vf610-mscm: support NVIC parent irqchip: nvic: increase number of external interrupts to 112 clocksource: add dependencies for Vybrid pit clocksource ARM: unify MMU/!MMU addruart calls ARM: imx: depend MXC debug board on 3DS machines ARM: allow MULTIPLATFORM with !MMU ARM: vf610: enable Cortex-M4 on Vybrid SoC ARM: dts: add support for Vybrid running on Cortex-M4 ARM: vf610m4: add defconfig for Linux on Vybrids Cortex-M4 Documentation/devicetree/bindings/arm/fsl.txt | 3 ++ arch/arm/Kconfig | 56 +++++++++++++-------------- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/vf610m4-colibri.dts | 52 +++++++++++++++++++++++++ arch/arm/boot/dts/vf610m4.dtsi | 10 +++++ arch/arm/configs/efm32_defconfig | 2 + arch/arm/configs/vf610m4_defconfig | 53 +++++++++++++++++++++++++ arch/arm/include/debug/efm32.S | 2 +- arch/arm/kernel/debug.S | 2 +- arch/arm/kernel/entry-v7m.S | 8 ++-- arch/arm/mach-imx/Kconfig | 37 +++++++++++------- arch/arm/mach-imx/Makefile.boot | 0 arch/arm/mach-imx/mach-vf610.c | 1 + drivers/clocksource/Kconfig | 2 + drivers/irqchip/irq-nvic.c | 37 +++++++++++++++++- drivers/irqchip/irq-vf610-mscm.c | 31 ++++++++++++--- kernel/irq/generic-chip.c | 5 +-- 17 files changed, 243 insertions(+), 59 deletions(-) create mode 100644 arch/arm/boot/dts/vf610m4-colibri.dts create mode 100644 arch/arm/boot/dts/vf610m4.dtsi create mode 100644 arch/arm/configs/vf610m4_defconfig create mode 100644 arch/arm/mach-imx/Makefile.boot -- 2.2.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
