Beside the additional helper irq_chip_(enable|disable)_parent I also cleaned up Kconfig.debug by adding ARM_SINGLE_ARMV7M as UNCOMPRESS_INCLUDE/DEBUG_UNCOMPRESS dependencies. This avoids that each ARMv7-M ARCH_/SOC_ needs to be added. Shawn, if ok, could you pickup that patchset as Arnd suggested? I guess the IRQ stuff still should go through Jason's tree directly (Patch 1-5)? The patchset has proven to be working on the Cortex-M4 of the Vybrid SoC using a Colibri VF61 module. Note: The patch "ARM: ARMv7M: define size of vector table for Vybrid" has a dependency on "ARM: ARMv7-M: Enlarge vector table up to 256 entries" (Maxime Coquelin), which is in Russels patch system (marked as applied, see 8340/1). However, since the vector table defaults to 240 with that patch, defining the size of the vector table for Vybrid is not absolutely required. Therefor patch 6 can also be applied at a later point in time... Changes since v6: - Add genirq irq_chip_(enable|disable)_parent helper - Add ARM_SINGLE_ARMV7M to UNCOMPRESS_INCLUDE/DEBUG_UNCOMPRESS since all supported ARMv7-M platforms so far support early debug through DEBUG_LL Changes since v5: - Remove unnecessary empty lines in Kconfig - Add non-hierarchy helper irq_domain_set_info - Rebased on v4.1-rc1 Changes since v4: - Added ARM_SINGLE_ARMV7M as top-level config symbol for ARMv7-M architectures - Cleaned up unnecessary selects within SOC_VF610 - Added linux,stdout-path to device tree 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 Stefan Agner (13): irqdomain: Add non-hierarchy helper irq_domain_set_info genirq: Add irq_chip_(enable|disable)_parent 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: introduce ARM_SINGLE_ARMV7M for ARMv7-M platforms ARM: efm32: use ARM_SINGLE_ARMV7M ARM: vf610: enable Cortex-M4 configuration 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 | 41 ++++++----- arch/arm/Kconfig.debug | 4 +- arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/vf610m4-colibri.dts | 99 +++++++++++++++++++++++++++ arch/arm/boot/dts/vf610m4.dtsi | 50 ++++++++++++++ arch/arm/configs/efm32_defconfig | 1 + arch/arm/configs/vf610m4_defconfig | 42 ++++++++++++ arch/arm/include/debug/efm32.S | 2 +- arch/arm/kernel/debug.S | 2 +- arch/arm/mach-imx/Kconfig | 38 +++++----- 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 | 23 +++++-- include/linux/irq.h | 2 + include/linux/irqdomain.h | 8 +-- kernel/irq/chip.c | 28 ++++++++ kernel/irq/generic-chip.c | 5 +- kernel/irq/irqdomain.c | 21 ++++++ 23 files changed, 350 insertions(+), 53 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 -- 2.4.1 -- 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
