[PATCH v3 3/3] ARM: at91: remove unnecessary of_platform_default_populate calls

Rob Herring (Arm)
2026-01-05T21:07:05Z

The DT core will call of_platform_default_populate, so it is not
necessary for machine specific code to call it unless there are custom
match entries, auxdata or parent device. Neither of those apply here, so
remove the call.

v3:
- Fixup split between patch 2 and 3.

v2:
- Dust off and rebase to 6.18-rc1
- Add new platforms added since v1
