From f7d6dacb233e1fe7e99e766abddd2a0247957d80 Mon Sep 17 00:00:00 2001 From: Beleswar Padhi Date: Mon, 26 Aug 2024 16:18:14 +0530 Subject: [PATCH] arm64: dts: ti: k3-j7200-som-p0: Change timer nodes status to reserved The remoteproc firmware of R5F 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 | +-------------------+--------------------------+ Signed-off-by: Beleswar Padhi Link: https://lore.kernel.org/r/20240826104821.1516344-2-b-padhi@ti.com Signed-off-by: Nishanth Menon --- arch/arm64/boot/dts/ti/k3-j7200-som-p0.dtsi | 13 +++++++++++++ 1 file changed, 13 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j7200-som-p0.dtsi b/arch/arm64/boot/dts/ti/k3-j7200-som-p0.dtsi index deb380a83ea10..e78b4622a7d1f 100644 --- a/arch/arm64/boot/dts/ti/k3-j7200-som-p0.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j7200-som-p0.dtsi @@ -266,6 +266,19 @@ ti,cluster-mode = <0>; }; +/* Timers are used by Remoteproc firmware */ +&main_timer0 { + status = "reserved"; +}; + +&main_timer1 { + status = "reserved"; +}; + +&main_timer2 { + status = "reserved"; +}; + &main_r5fss0_core0 { mboxes = <&mailbox0_cluster1 &mbox_main_r5fss0_core0>; memory-region = <&main_r5fss0_core0_dma_memory_region>, -- 2.39.5
