- Rebased on Linux-6.1-rc7
- Replaced PATCH1 with a patch to initialize broadcast timer
Changes since v2:
- Include Conor's revert patch as the first patch and rebased other patches
- Update PATCH2 to document bindings for separate RISC-V timer DT node
- Update PATCH3 based on RISC-V timer DT node bindings
