Subject: [PATCH V2 0/5] MIPS: Loongson64: Fix and improve irqchip drivers
Date: Thu, 30 Jul 2020 16:51:25 +0800	[thread overview]
Message-ID: <1596099090-23516-1-git-send-email-chenhc@lemote.com> (raw)

Modernized Loongson64 platforms use a hierarchical interrupt controller
architecture. For LS7A PCH, the hierarchy (from inside to outside) is
CPUINTC --> LIOINTC --> HTVEC --> PCHPIC/PCHMSI. However, the current
status is that there are several bugs in the LIOINTC and PCHPIC drivers,
and the HTVEC driver should be improved to support 8 groups of vectors.
Loonson64C support only 4 groups of HT vectors, and Loongson64G support
as many as 8 groups, so the .dts file and dt-bindings description should
also be updated.

V1 -> V2:
1, Add a cover letter.
2, Add Reviewed-by and Tested-by tags.
3, Improve commit messages by adding Fixes: tags.
