Subject: [PATCH v5 6/7] riscv: dts: spacemit: add initial support for K3
SoC
SpacemiT K3 is equipped with 8 X100 cores, which are RVA23 compliant.
Add nodes of uarts, timer and interrupt-controllers. Also add M-mode
APLIC (maplic) and IMSIC (mimsic) nodes to represent the hardware
topology and ready for potential firmware usage.
Signed-off-by: Guodong Xu <guodong@...cstar.com>
---
v5: Update the copyright year to 2026.
Set M-mode maplic and mimsic status to "reserved".
Update the commit message per Yixun's suggestion.
In maplic node, use riscv,delegation to match kernel binding. OpenSBI
accepts both delegate and delegation, but the binding documents only
riscv,delegation.
v4: Fix missing blank space after commas in compatible string.
Add m-mode imsic and aplic node.
Reorder properties in simsic, saplic, mimsic, and maplic nodes
to match DTS coding style.
v3: Remove "supm" from the riscv,isa-extensions list.
v2: Remove aliases from k3.dtsi, they should be in board DTS.
Updated riscv,isa-extensions with new extensions from the extensions.yaml.
