Subject: [PATCH v7 05/16] firmware: arm_scmi: Use new trace event scmi_xfer_response_wait
Date: Mon, 29 Nov 2021 19:11:45 +0000	[thread overview]
Message-ID: <20211129191156.29322-6-cristian.marussi@arm.com> (raw)
In-Reply-To: <20211129191156.29322-1-cristian.marussi@arm.com>

Use new trace event to mark start of waiting for response section.

Signed-off-by: Cristian Marussi <cristian.marussi@arm.com>
---
v5 --> v6
- removed atomic flag / poll is enough
- added timeout field
v4 --> v5
- consider atomic_enable flag too
