| H A D | reset.c | b75c83d9 Wed Aug 17 12:27:30 CDT 2022 Cristian Marussi <cristian.marussi@arm.com> firmware: arm_scmi: Fix the asynchronous reset requests
SCMI Reset protocol specification allows the asynchronous reset request
only when an autonomous reset action is specified. Reset requests based
on explicit assert/deassert of signals should not be served
asynchronously.
Current implementation will instead issue an asynchronous request in any
case, as long as the reset domain had advertised to support asynchronous
resets.
Avoid requesting the asynchronous resets when the reset action is not
of the autonomous type, even if the target reset domain does, in general,
support the asynchronous requests.
