    Subject[PATCH 00/13] Modernize Loongson64 Machine
    Date
    Loongson have a long history of contributing their code to mainline kernel.
    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 peroid without proper
    maintainance and became outdated.

    This patchset brings modern DeviceTree and irqchip support to the Loongson64 machine, and leaves
    Loongson 2e/f alone since they are too legacy to touch.


    Jiaxun Yang (13):
    MIPS: Loongson64: Rename CPU TYPES
    MIPS: Loongson64: Sepreate loongson2ef/loongson64 code
    MAINTAINERS: Fix entries for new loongson64 path
    irqchip: Add driver for Loongson-3 I/O interrupt controller
    dt-bindings: interrupt-controller: Add Loongson-3 IOINTC
    irqchip: Add driver for Loongson-3 HyperTransport interrupt controller
    dt-bindings: interrupt-controller: Add Loongson-3 HTINTC
    irqchip: i8259: Add plat-poll support
    irqchip: mips-cpu: Convert to simple domain
    MIPS: Loongson64: Drop legacy IRQ code
    dt-bindings: mips: Add loongson cpus & boards
    MIPS: Loongson64: Add generic dts
    MIPS: Loongson64: Load built-in dtbs
