From: Ram Kumar Dwivedi
Date: Mon Aug 11 2025 - 10:36:47 EST
This patch series enables Multi-Circular Queue (MCQ) support for the UFS
host controller on Qualcomm SM8650 and SM8750 platforms. MCQ is a modern
queuing model that improves performance and scalability by allowing
multiple hardware queues.
Patch 1 updates the device tree bindings to allow the additional register
regions and reg-names required for MCQ operation.
Patches 2 and 3 update the device trees for SM8650 and SM8750 respectively
to enable MCQ by adding the necessary register mappings and MSI parent.
Patch 4 is streamlining UFS MCQ resource mapping with a single MCQ region
mapping.
Tested on SM8650 and SM8750.
Changes from v1:
1. As per Krzysztof's suggestion, replaced mcq_vs and mcq_sqd DT mappings
with a single MCQ region mapping.
2. Minor changes in commit messge as per Krzysztof's suggestion.
