Tool/software: Linux
Hi TI:
We use AM5718 platform.
SDK version is 04.01.00.06
We found an warning during booting.
WARNING: CPU: 0 PID: 1 at /home/davido/projects/rv700/workspace/build/arago-tmp-external-linaro-toolchain/work-shared/am57xx-rv700/kernel-source/drivers/bus/omap_l3_noc.c:147 l3_interrupt_handler+0x25c/0x36c

We found if we remove &wakeupgen GIC_SPI 10 from ocp.
This warning will disappear.

interrupts-extended = <&crossbar_mpu GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>;
1. Can you tell us the purpose about interrupts-extended = <&wakeupgen GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>?
2. Can we remove it from device tree? (dra7.dtsi)
Thanks
