Subject: [PATCH v2 3/3] remoteproc: wkup_m3: Set deny_sysfs_ops flag
Date: Fri, 20 Nov 2020 21:01:56 -0600 [thread overview]
Message-ID: <20201121030156.22857-4-s-anna@ti.com> (raw)
In-Reply-To: <20201121030156.22857-1-s-anna@ti.com>
The Wakeup M3 remote processor is controlled by the wkup_m3_ipc
client driver, so set the newly introduced 'deny_sysfs_ops' flag
to not allow any overriding of the remoteproc firmware or state
from userspace.
