[PATCH 3/3] ARM: dts: ixp4xx: Drop the reg-offset hack
From: Linus Walleij
Date: Wed Jul 08 2026 - 18:26:04 EST
The reg-offset hack only works when the IXP4xx platform is
running in big endian mode, and it is there to byte-offset
the byte where the serial registers appear in the BE config.
This is clearly wrong, workarounds need to be in the
drivers. Drop the reg-offset.
