| 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.
