Did as suggested, but it did not help booting warp7 with mainline.

Also applied your "clk: imx: do not sleep if IRQ's are still disabled"
patch and this is what I get:

(hangs here)

Do you select "CONFIG_ARMV7_PSCI_NR_CPUS    2"  from
include/configs/mx7_common.h in your mx7s board? Any ideas?

Thanks
