Subject: [PATCH 2/2] remoteproc: wkup_m3: Set deny_sysfs_ops flag
Date: Mon, 31 Jan 2022 19:41:52 +0530 [thread overview]
Message-ID: <1643638312-3912-3-git-send-email-p-mohan@ti.com> (raw)
In-Reply-To: <1643638312-3912-1-git-send-email-p-mohan@ti.com>
From: Suman Anna <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.
