Subject: [PATCH v6 0/3] Improve CLOCK_EVT_FEAT_C3STOP feature setting
Date: Tue, 3 Jan 2023 19:40:59 +0530 [thread overview]
Message-ID: <20230103141102.772228-1-apatel@ventanamicro.com> (raw)
This series improves the RISC-V timer driver to set CLOCK_EVT_FEAT_C3STOP
feature based on RISC-V platform capabilities.
These patches can also be found in riscv_timer_dt_imp_v6 branch at:
https://github.com/avpatel/linux.git
Changes since v5:
- Rebased on Linux-6.2-rc2
Changes since v4:
- Update commit text of PATCH1 based on Samuel's comments
- Renamed DT property "riscv,timer-can-wake-cpu" to
"riscv,timer-cannot-wake-cpu" in PATCH2 and PATCH3
- Updated description of DT property "riscv,timer-cannot-wake-cpu"
in PATCH2
Changes since v3:
- 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
Changes since v1:
- Rebased on Linux-5.19-rc8
- Renamed "riscv,always-on" DT property to "riscv,timer-can-wake-cpu"
