Hi All,
This series adds support for the below interfaces on AM69-SK platform:
- CAN support on both MCU and MAIN domains
- OSPI NOR flash support
v2: Changelog:
1) Removed CAN interface aliasing.
2) Updated bootph property on the leaf nodes.
Resending version 2 adding linux-arm-kernel mailing list
Link to v1: https://lore.kernel.org/lkml/20240118153524.4135901-1-sabiya.d@ti.com/
Link to v2: https://lore.kernel.org/all/1d5c0570-fa10-4b87-9833-1710f33db01f@ti.com/

AM69 SK board has several CAN bus interfaces on both MCU and MAIN domains.
This enables the CAN interfaces on MCU and MAIN domain.
