Most of these should be addressed by the other patches in the series,
that add devicetree bindings for things we use in the LXA TAC devicetree.

The patch to add this property is now in gpio/for-next.

Bindings for these properties are added in previous patches in this series
(which are not yet applied anywhere).

The 'spi-cpha' and 'spi-cpol' properties were not actually required, so I've
dropped them from the devicetree for the V2 I've just sent.
I've added a patch that adds bindings for 'interrupts' to the V2, so this should
be addressed as well.

This should also be addressed in the V2.

Thanks for checking out my patch!
