Hello all,
this serie add a DT support for the ATH79 SPI controller and fix a few
trivial bugs. While adding DT support we also remove the unused custom
controller data in favor of the generic GPIO based chip select.
The clock patch add the missing clk_un/prepare to fix the warnings once
the platform is moved to the generic clock framework.
Finally the last patch is to ensure that CS_HIGH chips using CS0 get the
proper CS level before the first transfer.

Set the OF node of the spi controller and use the generic GPIO based
chip select instead of the custom controller data. As the controller
data isn't used by any board just drop it.

Clocks should be prepared and unprepared, fix this by using
clk_prepare_enable() and clk_disable_unprepare() instead of
clk_enable() and clk_disable().

or I can resend the whole patch/serie if that's preferable.
