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.
