Although there is only one choice of chipselect it is necessary to
specify it. The driver cannot claim the gpio otherwise.

Hello Michal,

The patch looks good to me, just one small comment below.

NIT: this should be GPIO_ACTIVE_HIGH instead of 0 but maybe Kukjin or
Krzysztof can fixup when applying it?

Yes, the GPIO_ACTIVE_HIGH would be better. Can you re-spin the patch
with this change and respective Acks? Including mine ack:

to here  ---8<--------8<-----------

should be added under the following '---'.

Please add some additional comments like above 'changes since previous version'
under the following '---' not '--', because all comments will be logged before
the '---' and I don't want to keep the changes basically.

Anyway, applied with removing above comments.

Thanks,
Kukjin
