Subject: [PATCH v2 1/5] arm64: dts: ti: k3-j7200: Change timer nodes status to reserved
Date: Wed, 14 Aug 2024 16:11:47 +0530 [thread overview]
Message-ID: <20240814104151.2038457-2-b-padhi@ti.com> (raw)
In-Reply-To: <20240814104151.2038457-1-b-padhi@ti.com>
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, main_timer2 |
+-------------------+--------------------------+
| main_r5fss0_core1 | main_timer1 |
+-------------------+--------------------------+
This change is already incorporated for timer nodes in the MCU voltage
domain.
