Subject: [PATCH v2 0/4] ufs: Add support for AMD Versal Gen2 UFS
Date: Tue, 21 Oct 2025 16:59:59 +0530 [thread overview]
Message-ID: <20251021113003.13650-1-ajay.neeli@amd.com> (raw)
This patch series adds support for the UFS driver on the AMD Versal Gen 2 SoC.
It includes:
- Device tree bindings and driver implementation.
- Secure read support for the secure retrieval of UFS calibration values.
The UFS host driver is based upon the Synopsis DesignWare (DWC) UFS architecture,
utilizing the existing UFSHCD_DWC and UFSHCD_PLATFORM drivers.
---
Changes in v1->v2:
- Address review comments from v1:
Rewritten commit message to clarify this as UFS driver for AMD Versal Gen 2 SoC.
Removed patch that utilized reserved bits for vendor-specific interrupts.
Moved the PHY reset logic to ufs-host-init to prevent unhandled interrupts.
