Subject: [PATCH 4/8] ARM: dts: Use generic DMA bindings for Exynos4 SPI devices
Date: Fri, 21 Jun 2013 14:50:20 +0200 [thread overview]
Message-ID: <1371819024-12596-5-git-send-email-s.nawrocki@samsung.com> (raw)
In-Reply-To: <1371819024-12596-1-git-send-email-s.nawrocki@samsung.com>
The Exynos4 SPI controller uses the PL330 DMA controller which has
migrated to the generic DMA bindings since commit b5be04d35dbb2e00
"spi: s3c64xx: Modify SPI driver to use generic DMA DT support".
Use the generic bindings to specify the corresponding DMA to make
the SPI usable again on Exynos4x12 SOCs.
