Subject: [PATCH RESEND V3 5/5] spi: s3c64xx: Added support for exynos5440 spi
Date: Mon, 15 Apr 2013 14:10:30 +0530	[thread overview]
Message-ID: <1366015230-18243-4-git-send-email-ks.giri@samsung.com> (raw)
In-Reply-To: <1366015230-18243-1-git-send-email-ks.giri@samsung.com>

From: Girish K S <girishks2000@gmail.com>

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.
