Subject: [PATCH V7 3/3] firmware: imx: imx-scu: register build-in child devices
Date: Wed, 6 Mar 2019 01:06:33 +0000 [thread overview]
Message-ID: <1551834095-19950-3-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1551834095-19950-1-git-send-email-Anson.Huang@nxp.com>
For some devices which are controlled by system controller,
they are NOT present in device tree since no hardware info
needed, just register these devices as children of SCU device.
This patch registers i.MX system controller watchdog platform
device as child device of SCU.
