Linux 7.3 merges SoC updates that add new chips while dropping support for older 32-bit ARM platforms, which leaves hundreds of drivers unmaintained
Engineers must now assume responsibility for the orphaned drivers or seek alternative hardware solutions. This shift affects maintenance budgets and may force updates to dependent systems.

THE READ
What the cluster adds up to.
Linux 7.3 includes a set of SoC updates that have been merged into the kernel. These updates add support for several newer ARM system-on-chip designs. At the same time, the kernel removes support for a number of older 32-bit ARM platforms. The deprecation is part of the regular cleanup of legacy hardware support.
As a result of dropping those platforms, the drivers tied to them are now orphaned. Orphaned means no maintainer is assigned to those driver trees in the mainline. Hundreds of driver files are affected by this change.
Engineers who rely on those drivers must now decide whether to take over maintenance. Alternatively, they may need to migrate to supported hardware or maintain an out-of-tree patch set. Assuming maintenance increases the workload for teams managing legacy ARM devices. The decision impacts both development schedules and long-term support plans.
On the deprecated platforms, the orphaned drivers will not receive bug fixes or security updates from the mainline. This can lead to incompatibility with newer kernel features or libraries. Systems that cannot be upgraded may face reduced reliability over time.
While the kernel gains support for newer SoCs, the net effect is a reduction in the breadth of 32-bit ARM coverage. Projects that depend on the orphaned drivers must evaluate the cost of maintaining them versus moving to supported platforms. The change reflects the kernel’s ongoing focus on current hardware while phasing out older architectures.
