Subject: [PATCH 00/12] Add TI-SCI reboot driver
Date: Wed, 31 Jan 2024 16:19:45 -0600 [thread overview]
Message-ID: <20240131221957.213717-1-afd@ti.com> (raw)
Hello all,
While PCSI normally handles reboot for K3, this is an available
fallback in case PCSI reboot fails. This driver is registered
with low priority as we want PSCI to remain the main way these
devices are rebooted.
The important part is the binding/DT changes. Currently in
U-Boot (which use the Linux device trees) we may not have
PSCI available yet (pre TF-A) and so we need this node
to correctly reboot. Adding this node in U-Boot is one of
the last remaining deltas between the two project DT files.
Thanks,
Andrew
