Subject: [PATCH 2/5] dt-bindings: mailbox: imx-mu: add i.MX93 S4 MU support
Date: Mon, 7 Feb 2022 17:58:29 +0800 [thread overview]
Message-ID: <20220207095832.1590225-3-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20220207095832.1590225-1-peng.fan@oss.nxp.com>
From: Peng Fan <peng.fan@nxp.com>
Similar to i.MX8ULP S4 MU, i.MX93 MU is dedicated for communication
between Sentinel and Cortex-A cores from hardware design, it could not be
reused for other purpose.
However i.MX93 S4 MU use seperate tx/rx interrupt, so update
interrupts and add interrupt-names property.
