Subject: [PATCH v6 2/5] firmware: meson_sm: populate platform device based on the child node
Date: Tue, 14 Jan 2020 11:45:24 +0800 [thread overview]
Message-ID: <1578973527-4759-3-git-send-email-xingyu.chen@amlogic.com> (raw)
In-Reply-To: <1578973527-4759-1-git-send-email-xingyu.chen@amlogic.com>
The child node of secure-monitor cann't be populated as platform device
automatically during the kernel initialization phase, so we invoke
of_platform_default_populate() to do it.
