ARM: imx6: report soc info via soc device
The patch enables soc bus infrastructure and adds a function imx_soc_device_init() to report soc info via soc device interface for imx6qdl and imx6sl. With the support, user space can get soc related info by looking at sysfs like below. $ cat /sys/devices/soc0/machine Freescale i.MX6 Quad SABRE Smart Device Board $ cat /sys/devices/soc0/family Freescale i.MX $ cat /sys/devices/soc0/soc_id i.MX6Q $ cat /sys/devices/soc0/revision 1.2 Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
