However, it seems like recent years, they are focusing on maintain a kernel= by themselves rather than contribute there code to the community. Kernel is progress rapidly too. Their code slept in mainline for a long per= oid without proper maintainance and became outdated. This patchset brings modern DeviceTree and irqchip support to the Loongson6= 4 machine, and leaves Loongson 2e/f alone since they are too legacy to touch. PCI and some legacy I/O device will be converted later, together with LS7A = PCH support. v1: - dt-bindings fixup according to Rob's comments - irqchip fixup according to Marc's comments - ls3-iointc: Make Core&IP map per-IRQ - Regenerate kconfigs - Typo & style improvements v2: - dt-bindings: Fix IOINTC, collect Rob's review tag - dtbs: Drop CPU Node, merge different ways according to Huacai and Paul's = comments v3: - Split code have been merged - Fix IOINTC binding to allow map any child IRQ to and parent - Convert "HTINTC" into "HTPIC", which mixed HT vectors processing and i825= 9 - Naming style fix according to Huacai's suggestions v4: - More naming related fixes Jiaxun Yang (10): irqchip: Add driver for Loongson I/O Local Interrupt Controller dt-bindings: interrupt-controller: Add Loongson LIOINTC irqchip: Add driver for Loongson-3 HyperTransport PIC controller dt-bindings: interrupt-controller: Add Loongson-3 HTPIC irqchip: mips-cpu: Convert to simple domain MIPS: Loongson64: Drop legacy IRQ code dt-bindings: mips: Add loongson boards MIPS: Loongson64: Add generic dts MIPS: Loongson64: Load built-in dtbs MIPS: Loongson64: Move MIPS_CPU_IRQ_BASE .../interrupt-controller/loongson,htpic.yaml | 59 +++ .../loongson,liointc.yaml | 93 +++++ .../bindings/mips/loongson/devices.yaml | 29 ++ arch/mips/Kconfig | 6 +- arch/mips/boot/dts/Makefile | 1 + arch/mips/boot/dts/loongson/Makefile | 4 + .../boot/dts/loongson/loongson3-package.dtsi | 62 ++++ .../dts/loongson/loongson3_4core_rs780e.dts | 25 ++ .../dts/loongson/loongson3_8core_rs780e.dts | 25 ++ arch/mips/boot/dts/loongson/rs780e-pch.dtsi | 26 ++ arch/mips/include/asm/i8259.h | 1 + .../include/asm/mach-loongson64/boot_param.h | 2 + .../asm/mach-loongson64/builtin_dtbs.h | 13 + arch/mips/include/asm/mach-loongson64/irq.h | 31 +- .../include/asm/mach-loongson64/loongson.h | 1 + arch/mips/loongson64/Makefile | 2 +- arch/mips/loongson64/env.c | 23 ++ arch/mips/loongson64/init.c | 6 + arch/mips/loongson64/irq.c | 162 --------- arch/mips/loongson64/setup.c | 16 + arch/mips/loongson64/smp.c | 28 +- drivers/irqchip/Kconfig | 19 + drivers/irqchip/Makefile | 2 + drivers/irqchip/irq-i8259.c | 6 +- drivers/irqchip/irq-loongson-htpic.c | 146 ++++++++ drivers/irqchip/irq-loongson-liointc.c | 338 ++++++++++++++++++ drivers/irqchip/irq-mips-cpu.c | 2 +- 27 files changed, 912 insertions(+), 216 deletions(-) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/= loongson,htpic.yaml create mode 100644 Documentation/devicetree/bindings/interrupt-controller/= loongson,liointc.yaml create mode 100644 Documentation/devicetree/bindings/mips/loongson/devices= .yaml create mode 100644 arch/mips/boot/dts/loongson/Makefile create mode 100644 arch/mips/boot/dts/loongson/loongson3-package.dtsi create mode 100644 arch/mips/boot/dts/loongson/loongson3_4core_rs780e.dts create mode 100644 arch/mips/boot/dts/loongson/loongson3_8core_rs780e.dts create mode 100644 arch/mips/boot/dts/loongson/rs780e-pch.dtsi create mode 100644 arch/mips/include/asm/mach-loongson64/builtin_dtbs.h delete mode 100644 arch/mips/loongson64/irq.c create mode 100644 drivers/irqchip/irq-loongson-htpic.c create mode 100644 drivers/irqchip/irq-loongson-liointc.c --=20 2.25.0
