Subject: [PATCH v5 00/11] Add SiFive TMC0 and SMC0 driver
Date: Tue, 02 Sep 2025 10:24:39 +0800	[thread overview]
Message-ID: <20250902-cache-upstream-v5-0-af60a067f47a@sifive.com> (raw)

SiFive TMC0 and SMC0 are the power controllers that controls the Tile and
CoreComplex power domain. Add the drivers to support the power
management features such as HSM STOP and System Suspend.

Features such as power management may require flushing the entire
cache before entering a non-retention power state. To support this, a
simple cache flush framework is introduced to allow the external CMO
to perform a full cache flush.

---
Changes in v5:
- Put the SiFive TMC0 driver to the fdt_early_driver
- Fix the format of the comments in SiFive TMC0 driver

Changes in v4:
- Call fdt_cmo_init() directly as part of generic_early_init()
- Rename SBI_HART_EXT_XSF* to SBI_HART_EXT_XSIFIVE*
- Move the TMC0 driver to the lib/utils/hsm/
- Move the SMC0 driver to the lib/utils/suspend/

Changes in v3:
- Add the SiFive TMC and SMC driver

Changes in v2:
- Since the platform override hooks was deprecated, use the fdt_driver
for initializing the sifive_dev_platform.
