From 754d60ad1c91895be0bc7d771fbf9fb3c9448640 Mon Sep 17 00:00:00 2001 From: Alexander Dahl Date: Wed, 29 Apr 2026 14:59:30 +0200 Subject: [PATCH] memory: atmel-ebi: Allow deferred probing After removing of_platform_default_populate() calls the atmel-ebi driver was affected by deferred probing. platform_driver_probe() is incompatible with deferred probing. This led to atmel-ebi driver eventually not being probed on at91 sam9x60-curiosity and other sam9x60 based boards. Subsequently the nand-controller driver (nand-controller being a child node of ebi) on that platform was not probed and thus raw NAND flash was inaccessible, preventing devices to boot with rootfs on raw NAND flash (e.g. with UBI/UBIFS).
