Subject: [PATCH v2] firmware: meson_sm: populate platform devices from sm device tree data
Date: Fri, 24 Mar 2023 17:01:41 +0300 [thread overview]
Message-ID: <20230324140141.6743-1-ddrokosov@sberdevices.ru> (raw)
In some meson boards, secure monitor device has children, for example,
power secure controller. By default, secure monitor isn't the bus in terms
of device tree subsystem, so the of_platform initialization code doesn't
populate its device tree data. As a result, secure monitor's children
aren't probed at all.
Run the 'of_platform_populate()' routine manually to resolve such issues.
