From: marco
Subject: [PATCH] hw/arm/mps2-tz.c: fix RX/TX interrupts order
Date: Tue, 30 Jul 2024 07:31:20 +0000

From: Marco Palumbi <Marco.Palumbi@tii.ae>

The order of the RX and TX interrupts are swapped.
This commit fixes the order as per the following documents:
 * https://developer.arm.com/documentation/dai0505/latest/
 * https://developer.arm.com/documentation/dai0521/latest/
 * https://developer.arm.com/documentation/dai0524/latest/
 * https://developer.arm.com/documentation/dai0547/latest/
