[PATCH 07/21] ARM: ux500: move SPI pin config to device tree
Linus Walleij
linus.walleij at linaro.org
Sun Nov 17 06:03:56 EST 2013
This moves the SPI pin control table out of the board file
and into the device tree. Move the specific setting for
SSP0 on the HREFprev60 into the prev60-specific DTS file.
The SPI2 configuration is not really connected to any device,
as it will conflict with GPIO218 which is used on all HREFs.
