From 241aba6c1ebd2c326a371b8af84b1f096efd0506 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 9 Mar 2022 18:03:42 +0800 Subject: [PATCH] dt-bindings: mailbox: imx-mu: add i.MX93 S4 MU support 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 separate tx/rx interrupt, so update interrupts and add interrupt-names property.
