Subject: [PATCH v3 8/8] remoteproc: qcom: Introduce panic handler for PAS and ADSP
Date: Mon, 10 Feb 2020 16:50:59 -0800	[thread overview]
Message-ID: <20200211005059.1377279-9-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20200211005059.1377279-1-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.

Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
