Subject: [PATCH 1/2] EDAC: synopsys: Add disable_intr support for V3.X Synopsys EDAC DDR
Date: Fri, 18 Mar 2022 19:17:41 +0800 [thread overview]
Message-ID: <20220318111742.15730-2-sherry.sun@nxp.com> (raw)
In-Reply-To: <20220318111742.15730-1-sherry.sun@nxp.com>
V3.X Synopsys EDAC DDR doesn't have the QOS Interrupt register, need
to change to use the ECC Clear Register to disable the interrupts.
