Add i.MX SCU SoC info driver to support i.MX8QXP SoC, introduce driver dependency into Kconfig as CONFIG_IMX_SCU must be selected to support i.MX SCU SoC driver, also need to use platform driver model to make sure IMX_SCU driver is probed before i.MX SCU SoC driver. With this patch, SoC info can be read from sysfs: i.mx8qxp-mek# cat /sys/devices/soc0/family Freescale i.MX i.mx8qxp-mek# cat /sys/devices/soc0/soc_id 0x2 i.mx8qxp-mek# cat /sys/devices/soc0/machine Freescale i.MX8QXP MEK i.mx8qxp-mek# cat /sys/devices/soc0/revision 1.1 Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Reviewed-by: Abel Vesa <abel.vesa@nxp.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

If you say yes here you get support for the NXP i.MX System
|
|
Controller Unit SoC info module, it will provide the SoC info
|
|
like SoC family, ID and revision etc.
