[PATCH 0/2] amba/serial: amba-pl011: Bring back zx29 UART support

From: Stefan Dösinger

Date: Wed May 13 2026 - 17:35:16 EST


This is based on code removed in commit 89d4f98ae90d ("ARM: remove zte
zx platform"). It was previously discussed and reviewed on the
linux-arm-kernel mailing list as part of my patchset to add initial
support for ZTE's zx297520v3 router board. I am sending the two UART
driver patches to linux-serial. The rest goes through the soc list.

Note that the first patch (LLDEBUG) uses a Kconfig symbol introduced by
my platform patch, which was sent to the soc mailing list. I don't know
what the correct way to handle this is. I can delay/resend this patchset
after the soc changes are merged.
