Subject: [PATCH v3 1/3] drivers: bus: simple-pm-bus: Populate simple MFD child devices
Date: Thu, 4 Aug 2022 14:11:31 +0800 [thread overview]
Message-ID: <20220804061133.4110734-2-victor.liu@nxp.com> (raw)
In-Reply-To: <20220804061133.4110734-1-victor.liu@nxp.com>
There could be simple MFD device(s) connected to a simple PM bus as child
node(s), like Freescale i.MX8qxp pixel link MSI bus. Add a child match
table as an argument to of_platform_populate() function call to specify
the simple MFD devices so that they can be populated.
