4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cyrille Pitchen <cyrille.pitchen@xxxxxxxxx>
commit 70f340df24518d36eeaefb6652d492f250115c19 upstream.
The non-DT platform that uses this driver (actually the AVR32) was taking a bad
branch for determining if the IP would use gpio for CS.
Adding the presence of DT as a condition fixes this issue.
Fixes: 4820303480a1 ("spi: atmel: add support for the internal chip-select of the spi controller")
