Missed to reply you. So do you agree to split this patch into two patches ? or leave the code as it is? The first is follow other i.mx6/7 to check return value of imx_soc_device_init. The second is drop the call to of_platform_default_populate.

So probably leave as it is unless we have more strong reasons. Sorry about that.

Follow other i.MX6/7 machince code to check return value of imx_soc_device_init and warn when fail. Also drop of_platform_default_populate, because "arch_initcall_sync(of_platform_default_populate_init);" could be used to populate the device tree.
