Subject: [PATCH 9/9] remoteproc: qcom: Introduce panic handler for PAS and ADSP
Date: Tue,  6 Aug 2019 22:39:42 -0700	[thread overview]
Message-ID: <20190807053942.9836-10-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20190807053942.9836-1-bjorn.andersson@linaro.org>

Make the PAS and ADSP/CDSP remoteproc drivers implement the panic
handler that will invoke a stop to prepare the remoteprocs for post
mortem debugging.
