Subject[PATCH] ARM: at91/dt: Disable SPI on at91sam9x5ek to allow MCI1 to work.
Message-ID<tbxSN-11y-7@gated-at.bofh.it>
From: Cristian Birsan <cristian.birsan@microchip.com>

The A13 hardware line is shared by SPI and MCI1 controller.This patch
disables the SPI controller so that the MCI1 (the big MMC card slot) can
be used.
