SPI controllers may need to be properly setup before chip selects
can be used. Therefore, wait until the spi controller has a chance
to perform their setup procedure before trying to use the chip
select.

This also insures that the chip selects pins are in a good
state before asseting them which otherwise may cause confusion.

Does it mean I have to test it again?
Oops sorry. No the patch hasn't changed. I can shoot a v3 with your tested by included.
Whatever Mark prefers.
Hi Mark,
I don't see that you pulled this patch into your topic/core branch just yet. Would you prefer
for me to shoot a v3 with Andy's tested by or will you just add it when your ready to
pull it in?

Without this patch several of our boards don't boot in linux-next so if there is anything you
need for me to do please let me know.
