On the other hand I have validated this patch-series on both AM37xEVM
and BeagleBone platform. I used the test code which you shared with me
to validate it.

AM33XX Clock tree needs minor change here,


 int __init am33xx_clk_init(void)


Thanks,
Vaibhav

Ok, do you plan to submit this? If I need to do a V2 of this series, I
can include this one too.
