Subject: [PATCH] remoteproc: qcom_q6v5: don't auto boot remote processor
Date: Thu, 24 May 2018 22:21:41 +0300
Message-ID: <20180524192141.20323-1-ramon.fried@gmail.com> (raw)

Sometimes that rmtfs userspace module is not brought
up fast enough and the modem crashes.
disabling automated boot in the driver and triggering
the boot from user-space sovles the problem.
