AM67: How to enable MACN in linux of AM67?

Hi Zekun,

MCAN support for AM67/J722S has been added in 10.0 SDK which uses the 6.6 kernel of Linux. 

You may reference the device tree used in 10.0 SDK and patch if you wish to port back to 9.2 SDK:

• https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-j722s-evm.dts?h=ti-linux-6.6.y
• https://lore.kernel.org/linux-arm-kernel/20240621091057.1473010-1-b-kapoor@ti.com/T/ 

Otherwise, if using the 10.0 SDK and the prebuilt SD card image, it should already have MCAN enabled. So, the CAN utility tools can be ran to do some basic tests: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-am67a/10_00_00/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/MCAN.html
