Subject: [RFC 1/4] ARM: imx: use device_initcall for imx_soc_device_init
Date: Thu, 16 Jan 2020 09:36:48 +0000 [thread overview]
Message-ID: <1579167145-1480-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1579167145-1480-1-git-send-email-peng.fan@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
This is preparation to move imx_soc_device_init to drivers/soc/imx/
There is no reason to must put dt devices under /sys/devices/soc0,
they could also be under /sys/devices/platform, so we could
pass NULL as parent when calling of_platform_default_populate.
Following soc-imx8.c soc-imx-scu.c using device_initcall, need
to change return type to int type for imx_soc_device_init.
