Subject: [PATCH v7 00/12] Modernize Loongson64 Machine v6
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maintainance and became outdated.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
v4:
- More naming related fixes
v5:
- irqchip fixes thanks to maz (see per file changelog)
- Remove unnecessary details in dt-bindings
- Credit Huacai with Co-developed-by
v6:
- HTPIC minor fix
- device binding naming fix
v7:
- Add Huacai's sign-off
- Fix all reasonable checkpatch warnings
