Subject: [PATCH v4 4/4] remoteproc: qcom: Introduce panic handler for PAS and ADSP
Date: Mon,  9 Mar 2020 23:38:17 -0700
Message-ID: <20200310063817.3344712-5-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20200310063817.3344712-1-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>
