This patch series enables Multi-Circular Queue (MCQ) support for the UFS host controller on Qualcomm SM8650 and SM8750 platforms. MCQ improves performance and scalability by allowing multiple hardware queues. The series streamlines MCQ resource mapping by using a single MCQ region mapping instead of multiple separate resource regions, making the driver more maintainable and less prone to resource mapping errors. Patch 1 streamlines UFS MCQ resource mapping with a single MCQ region mapping, simplifying the current approach that involved multiple resource mappings and dynamic resource allocation. Patch 2 refactors MCQ register dump logic to align with the new resource mapping approach, updating function signatures and using direct base addresses. Patch 3 removes the unused ufshcd_res_info structure and associated enum definitions that are no longer needed after the resource mapping refactor. Patches 4 and 5 update the device trees for SM8650 and SM8750 respectively to enable MCQ by adding the necessary register mappings and MSI parent. Tested on SM8650 and SM8750. Changes from v2: 1. Removed dt-bindings patch as existing binding supports required reg-names format. 2. Added patch to refactor MCQ register dump logic for new resource mapping. 3. Added patch to remove unused ufshcd_res_info structure from UFS core. 4. Changed reg-names from "ufs_mem" to "std" in device tree patches. 5. Reordered patches with driver changes first, then device tree changes. 6. Updated SM8750 MCQ region size from 0x2000 to 0x15000 Nitin Rawat (3): ufs: ufs-qcom: Streamline UFS MCQ resource mapping ufs: ufs-qcom: Refactor MCQ register dump logic scsi: ufs: core: Remove unused ufshcd_res_info structure Palash Kambar (1): arm64: dts: qcom: sm8750: Enable MCQ support for UFS controller Ram Kumar Dwivedi (1): arm64: dts: qcom: sm8650: Enable MCQ support for UFS controller arch/arm64/boot/dts/qcom/sm8650.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8750.dtsi | 8 +- drivers/ufs/host/ufs-qcom.c | 180 +++++++++++---------------- drivers/ufs/host/ufs-qcom.h | 22 +++- include/ufs/ufshcd.h | 25 ---- 5 files changed, 104 insertions(+), 138 deletions(-) -- 2.50.1
