Splitted out version of the MSCM driver. My first driver based on the routeable domain support and was part of the Vybrid Cortex-M4 support patchset. So far the MSCM interrupt router was initialized by the boot loader and configured all interrupts for the Cortex-A5 CPU. There are two use cases where a proper driver is necessary: - To run Linux on the Cortex-M4. When the kernel is running on the non-preconfigured CPU, the interrupt router need to be configured properly. - To support deeper sleep modes: LPSTOP clears the interrupt router configuration, hence a driver needs to restore the configuration on resume. I created a seperate patchset for that driver which hopefully makes it easier to get it into mergeable state. Since I identified some registers likely to be used by other drivers (e.g. CPU ID or the CPU Generate Interrupt Register) I also added the "syscon" compatible string to make the registers available for other drivers in case needed. This resend version of this patchset is rebased on v3.19-rc4. Changes since v2 - Use two cell layout for MSCM interrupt router - Move peripheral interrupt properties to base device tree vfxxx.dtsi - Use generic two cell xlate (irq_domain_xlate_twocell) - Add syscon to compatible string - Remove some line breaks for better readability Changes since v1 (part of Vybrid Cortex-M4 support) - Rewrite with irqdomain hierarchy - Implemented as proper irqchip and move to driver/irqchip/ - Doesn't work on Cortex-M4 anymore (NVIC as parent is not yet implemented) Stefan Agner (3): irqchip: vf610-mscm: add support for MSCM interrupt router irqchip: vf610-mscm: dt-bindings: add MSCM bindings ARM: dts: vf610: add Miscellaneous System Control Module (MSCM) .../bindings/arm/freescale/fsl,vf610-mscm.txt | 19 +++ arch/arm/boot/dts/vf500.dtsi | 128 +------------- arch/arm/boot/dts/vfxxx.dtsi | 42 +++++ arch/arm/mach-imx/Kconfig | 1 + drivers/irqchip/Kconfig | 11 ++ drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-vf610-mscm.c | 186 +++++++++++++++++++++ 7 files changed, 264 insertions(+), 124 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/freescale/fsl,vf610-mscm.txt create mode 100644 drivers/irqchip/irq-vf610-mscm.c -- 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
