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
Message-ID: <1578973527-4759-3-git-send-email-xingyu.chen@amlogic.com>

Precedence: bulk

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.
