Subject: spi: s3c64xx: Added support for exynos5440 spi
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bff82038ca3e2976ad0b51d32c7a8c9ed31065f7;p=linux-beck.git

spi: s3c64xx: Added support for exynos5440 spi

This patch adds support for the exynos5440 spi controller.
The integration of the spi IP in exynos5440 is different from
other SoC's. The I/O pins are no more configured via gpio, they
have dedicated pins.
