[PATCH V2 0/2] Add CAN and OSPI support for AM69-SK platform

[sabiya.d]

From: Dasnavis Sabiya <sabiya.d@ti.com>

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.

Link to v1: https://lore.kernel.org/lkml/20240118153524.4135901-1-sabiya.d@ti.com/
