Subject: [PATCH] scsi: ufs: dt-bindings: Add missing mcq reg for qcom,sa8255p-ufshc
Date: Thu, 16 Jul 2026 16:33:13 +0800 [thread overview]
Message-ID: <20260716083313.2367249-1-shengchao.guo@oss.qualcomm.com> (raw)
Qualcomm UFS controller found on SoCs SA8255P/SA8797P has a MCQ I/O
address space. It should be defined in the bindings even though Linux
driver currently doesn't utilize it. Fix the binding before it gets
adopted by DTS.
Fixes: e2725ed2a7fb ("scsi: ufs: dt-bindings: Document bindings for SA8255P UFS Host Controller")
