The remoteproc firmware like of R5F and DSPs in the MAIN voltage domain
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 |
+-------------------+-------------+
| c7x_0 | main_timer1 |
+-------------------+-------------+
| c7x_1 | main_timer2 |
+-------------------+-------------+
This change is already incorporated for timer nodes in the MCU voltage
domain.
Fixes: 3308a31c507c ("arm64: dts: ti: k3-am62: Add general purpose timers for am62")
Please check Fixes tag once.
AFAIR, J722S uses am62p not am62
