Subject: [V4 2/2] remoteproc: qcom_q6v5: Introduce panic handler for MSS
Date: Tue, 24 May 2022 18:15:35 +0530	[thread overview]
Message-ID: <1653396335-6295-3-git-send-email-quic_sibis@quicinc.com> (raw)
In-Reply-To: <1653396335-6295-1-git-send-email-quic_sibis@quicinc.com>

Make the MSS q6v5 remoteproc drivers implement the panic handler
that will invoke a stop to prepare the remoteprocs for post mortem
debugging.
