| |
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 separate tx/rx interrupt, so update interrupts and add interrupt-names property.
