Hi ARM SoC folks, the build robot came back with a minor snag after 4 days, so I fixed the offending commit and pushed an identical tag with this fixed. (No COMPILE_TEST on the GPIO driver because it depends on the irqchip that is IXP4xx-specific.)

Merged now. Thanks! -Olof
Hi Arm SoC folks! Here is the big pull request for the first step of the much overdue IXP4xx modernization. As explained earlier this platform has many active users and specific industrial properties that make it hard to replace, and thus lives on, and we need to maintain it going forward. I can't really wait any longer for more ACKs, and just conclude noone has any serious objections, certainly not anything I can't fix up in-tree if need be. This really needs to go into linux-next now and into v5.2, as all later modernizations need to have this base to make it possible to modernize in a per-subsystem manner going forward. The idea is of course to aim for complete device tree migration and deletion of board file code and callbacks eventually. Right now the device tree boot is pretty orthogonal from the board file boot, once we get PCI sorted we can start deleting some board files that need little more than what we have here and PCI. Please pull it in for v5.2. Yours, Linus Walleij The following changes since commit 9e98c678c2d6ae3a17cb2de55d17f69dddaa231b: Linux 5.1-rc1 (2019-03-17 14:22:26 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik.git tags/ixp4xx-for-armsoc for you to fetch changes up to 4e3bfcd70f9f3559c8591a1e29140300821eb5b0: ARM: dts: Add queue manager and NPE to the IXP4xx DTSI (2019-04-19 20:40:16 +0200) ---------------------------------------------------------------- This modernizes the IXP4xx platform and adds initial Device Tree Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to offset 16, converts to SPARSE_IRQ, then we add proper subsystem drivers in each subsystem for irqchip, GPIO and clocksource and switch over to using these new drivers. Next we modernize the NPE and QMGR drivers and push them down into drivers/soc. This has been tested on the IXP4xx NSLU2 and the Gateworks GW2358-4. ---------------------------------------------------------------- Linus Walleij (31): ARM: ixp4xx: Add myself as maintainer ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER ARM: ixp4xx: Pass IRQ resource to beeper ARM: ixp4xx: Convert to SPARSE_IRQ irqchip: Add driver for IXP4xx gpio: ixp4xx: Add driver for the IXP4xx GPIO ARM: ixp4xx: Switch to use new IRQ+GPIO drivers clocksource/drivers/ixp4xx: Add driver ARM: ixp4xx: Switch to use new timer driver irqchip: ixp4xx: Add DT bindings irqchip: ixp4xx: Add OF initialization support clocksource/drivers/ixp4xx: Add DT bindings clocksource/drivers/ixp4xx: Add OF initialization support gpio: ixp4xx: Add DT bindings gpio: ixp4xx: Add OF probing support ARM: ixp4xx: Add DT bindings ARM: ixp4xx: Add device tree boot support ARM: dts: Add some initial IXP4xx device trees ARM: ixp4xx: Move NPE and QMGR to drivers/soc ARM: ixp4xx: Move IXP4xx QMGR and NPE headers ARM: ixp4xx: Turn the NPE into a platform device ARM: ixp4xx: Turn the QMGR into a platform device soc: ixp4xx: npe: Pass addresses as resources soc: ixp4xx: Uninline several functions soc: ixp4xx: Remove unused functions soc: ixp4xx: qmgr: Pass resources soc: ixp4xx: Add DT bindings for IXP4xx NPE soc: ixp4xx: npe: Add DT probe code soc: ixp4xx: qmgr: Add DT bindings for IXP4xx qmgr soc: ixp4xx: qmgr: Add DT probe code ARM: dts: Add queue manager and NPE to the IXP4xx DTSI .../devicetree/bindings/arm/intel-ixp4xx.yaml | 22 + .../intel,ixp4xx-network-processing-engine.yaml | 44 ++ .../intel,ixp4xx-interrupt.yaml | 54 +++ .../bindings/misc/intel,ixp4xx-queue-manager.yaml | 49 +++ .../bindings/timer/intel,ixp4xx-timer.yaml | 42 ++ MAINTAINERS | 18 +- arch/arm/Kconfig | 5 +- arch/arm/boot/dts/Makefile | 3 + arch/arm/boot/dts/intel-ixp42x-linksys-nslu2.dts | 109 +++++ arch/arm/boot/dts/intel-ixp42x.dtsi | 25 ++ .../arm/boot/dts/intel-ixp43x-gateworks-gw2358.dts | 94 ++++ arch/arm/boot/dts/intel-ixp43x.dtsi | 15 + arch/arm/boot/dts/intel-ixp45x-ixp46x.dtsi | 34 ++ arch/arm/boot/dts/intel-ixp4xx.dtsi | 69 +++ arch/arm/mach-ixp4xx/Kconfig | 27 +- arch/arm/mach-ixp4xx/Makefile | 5 +- arch/arm/mach-ixp4xx/avila-pci.c | 2 + arch/arm/mach-ixp4xx/avila-setup.c | 2 + arch/arm/mach-ixp4xx/common.c | 484 ++++----------------- arch/arm/mach-ixp4xx/coyote-pci.c | 2 + arch/arm/mach-ixp4xx/coyote-setup.c | 2 + arch/arm/mach-ixp4xx/dsmg600-pci.c | 2 + arch/arm/mach-ixp4xx/dsmg600-setup.c | 5 +- arch/arm/mach-ixp4xx/fsg-pci.c | 2 + arch/arm/mach-ixp4xx/fsg-setup.c | 2 + arch/arm/mach-ixp4xx/gateway7001-pci.c | 2 + arch/arm/mach-ixp4xx/gateway7001-setup.c | 2 + arch/arm/mach-ixp4xx/gtwx5715-pci.c | 2 + arch/arm/mach-ixp4xx/gtwx5715-setup.c | 2 + arch/arm/mach-ixp4xx/include/mach/entry-macro.S | 41 -- arch/arm/mach-ixp4xx/include/mach/irqs.h | 75 ---- arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h | 94 ---- arch/arm/mach-ixp4xx/include/mach/qmgr.h | 204 --------- arch/arm/mach-ixp4xx/irqs.h | 68 +++ arch/arm/mach-ixp4xx/ixdp425-pci.c | 2 + arch/arm/mach-ixp4xx/ixdp425-setup.c | 2 + arch/arm/mach-ixp4xx/ixdpg425-pci.c | 2 + arch/arm/mach-ixp4xx/ixp4xx-of.c | 60 +++ arch/arm/mach-ixp4xx/nas100d-pci.c | 2 + arch/arm/mach-ixp4xx/nas100d-setup.c | 5 +- arch/arm/mach-ixp4xx/nslu2-pci.c | 2 + arch/arm/mach-ixp4xx/nslu2-setup.c | 12 +- arch/arm/mach-ixp4xx/wg302v2-pci.c | 2 + arch/arm/mach-ixp4xx/wg302v2-setup.c | 2 + drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-ixp4xx.c | 284 ++++++++++++ drivers/crypto/ixp4xx_crypto.c | 4 +- drivers/gpio/Kconfig | 13 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-ixp4xx.c | 474 ++++++++++++++++++++ drivers/input/misc/ixp4xx-beeper.c | 20 +- drivers/irqchip/Kconfig | 6 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-ixp4xx.c | 403 +++++++++++++++++ drivers/net/ethernet/xscale/ixp4xx_eth.c | 14 +- drivers/net/wan/ixp4xx_hss.c | 4 +- drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/ixp4xx/Kconfig | 16 + drivers/soc/ixp4xx/Makefile | 2 + .../soc/ixp4xx/ixp4xx-npe.c | 66 ++- .../soc/ixp4xx/ixp4xx-qmgr.c | 186 ++++++-- drivers/watchdog/ixp4xx_wdt.c | 9 + include/linux/irqchip/irq-ixp4xx.h | 12 + include/linux/platform_data/timer-ixp4xx.h | 11 + .../mach => include/linux/soc/ixp4xx}/npe.h | 2 -
