From af85d689ae08860e4f9648f05e09f1de868091f4 Mon Sep 17 00:00:00 2001 From: Ziqi Chen Date: Tue, 28 Nov 2023 12:07:47 +0800 Subject: [PATCH] scsi: ufs: dt-bindings: Add msi-parent for UFS MCQ The Message Signaled Interrupts (MSI) support has been introduced in UFSHCI version 4.0 (JESD223E). The MSI is the recommended interrupt approach for MCQ. If choose to use MSI, in UFS DT, we need to provide msi-parent property that point to the hardware entity which serves as the MSI controller for this UFS controller.
