Subject: [PATCH] Revert "powerpc: dts: mpc85xx: remove "simple-bus" compatible
from ifc node"
Date: Wed, 5 Nov 2025 12:55:24 -0800
This reverts commit 0bf51cc9e9e57a751b4c5dacbfa499ba5cd8bd72.
simple-bus is needed for legacy platforms such as P1010 so that nodes
are populated properly.
Fixes fsl,ifc-nand probing under at least P1010.
