There is no DSP on this SOC.
Please consider to re-word commit message
Thanks for catching this! Will fix in revision.
use timers. Therefore, change the status of the timer nodes to
"reserved" to avoid any clash. Usage is described as below:
+===================+==========================+
| Remoteproc node | Timer Node |
+===================+==========================+
| main_r5fss0_core0 | main_timer0, main_timer2 |
+-------------------+--------------------------+
| main_r5fss0_core1 | main_timer1 |
+-------------------+--------------------------+
This change is already incorporated for timer nodes in the MCU voltage
domain.
For whole series, on MCU domain R5 we have device-manager firmware,
which is needed to get SOC functional. So MCU domain timers are reserved.
Understood. Will fix in revision.
So my suggestion will be to avoid above message

timers")
