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maintainance and became outdated.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.

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 i8259
- Naming style fix according to Huacai's suggestions

Jiaxun Yang (10):
  dt-bindings: Document loongson vendor-prefix
  irqchip: Add driver for Loongson I/O interrupt controller
  dt-bindings: interrupt-controller: Add Loongson IOINTC
  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
