The fourth version has one small fix in the MSCM IR driver and one dependency fix. Like version 3 of the patchset, it does not contain the interrupt router driver anymore (MSCM IR). The driver has been merged inbetween: https://lkml.org/lkml/2015/3/8/6 This patchset extends the NVIC driver to support irq domain hierarchy and the MSCM IR 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. Since v2, this patchset also doesn't add any ARCH 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 selectable when the CPU ARCH_MULTI_V7M is selected, and hence allows to build a kernel for the Cortex-M4 CPU too. The patchset has proven to be working on the Cortex-M4 of the Vybrid SoC using a Colibri VF61 module. Changes since v3: - Added dependency IRQ_DOMAIN_HIERARCHY for ARM_NVIC - Fix MSCM IR disable function check - Remove "ARM: imx: depend MXC debug board on 3DS machines", the patch has been merged Changes since v2: - Update MSCM patches to merged version of MSCM interrupt router - Use the GPLv2/X11 dual license in the new device tree files - Drop SD controller in device tree (initramfs works now and is probably more appropriate for most cases) - Disable GPIO nodes since the A5 is using them - Drop CONFIG_ prefixes in Kconfig changes for MXC_DEBUG_BOARD - Drop vector table resizing in favor of Maxime Coquelin's patch (https://lkml.org/lkml/2015/2/20/399) - Remove !MMU dependency for ARCH_EFM32 since its part of ARCH_MULTI_V7M - Rebased on v4.0-rc1 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 (10): genirq: generic chip: support hierarchy domain irqchip: nvic: support hierarchy irq domain irqchip: vf610-mscm: support NVIC parent ARM: ARMv7M: define size of vector table for Vybrid clocksource: add dependencies for Vybrid pit clocksource ARM: unify MMU/!MMU addruart calls 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 | 54 +++++++-------- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/vf610m4-colibri.dts | 98 +++++++++++++++++++++++++++ arch/arm/boot/dts/vf610m4.dtsi | 50 ++++++++++++++ arch/arm/configs/efm32_defconfig | 2 + arch/arm/configs/vf610m4_defconfig | 43 ++++++++++++ arch/arm/include/debug/efm32.S | 2 +- arch/arm/kernel/debug.S | 2 +- arch/arm/mach-imx/Kconfig | 36 ++++++---- arch/arm/mach-imx/Makefile.boot | 0 arch/arm/mach-imx/mach-vf610.c | 1 + arch/arm/mm/Kconfig | 1 + drivers/clocksource/Kconfig | 2 + drivers/irqchip/Kconfig | 1 + drivers/irqchip/irq-nvic.c | 28 +++++++- drivers/irqchip/irq-vf610-mscm-ir.c | 32 +++++++-- kernel/irq/generic-chip.c | 5 +- 18 files changed, 306 insertions(+), 55 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 -- 2.3.5 -- 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
