Subject: [PATCH v3 2/2] memory: fsl_ifc: populate child devices without relying on simple-bus
Date: Tue, 16 Nov 2021 15:18:46 -0600 [thread overview]
Message-ID: <20211116211846.16335-3-leoyang.li@nxp.com> (raw)
In-Reply-To: <20211116211846.16335-1-leoyang.li@nxp.com>
After we update the binding to not use simple-bus compatible for the
controller, we need the driver to populate the child devices explicitly.
