  Cc: broonie, linux-arm-kernel, linux-samsung-soc, rob.herring,
	grant.likely, kgene.kim, jaswinder.singh

Changes since v4:
- Includes the missing gpio request for slave select line gpio as suggested
  by Mark Brown.

Changes since v3:
- Fixed the build breakage after applying 3rd patch in this series (which
  had dependency on the 6th patch). This was reported by Doug Anderson.

Changes since v2:
- Removed renaming of platform device name at runtime
- Includes other minor fixes suggested by Olof, Grant, Kukjin and Abhilash.
- Rebased to Linux 3.5-rc1

Changes since v1:
- Incorporated changes suggested by Mark Brown
 - Merged 2nd, 3rd and 5th patch into one single patch.
 - Listed the order of gpios in the device tree support documentation.
 - Switched to generic property names for chip select gpio line and
   number of slave select lines.
- Moved the platform enablement patches for Exynos4 and Exynos5 into a
 different patch series.
- Included Ack from Jaswinder Singh <jaswinder.singh@linaro.org>.

This patch series adds device tree based discovery support for Samsung's
s3c64xx compatible spi controller. This is mainly tested for Exynos4210
and Exynos5250 with onboard spi nor flash device.

The patch series (6 patches) that add board/platform specific support has
no changes since the v2 version. This series is available at:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-May/100812.html

+* Samsung SPI Controller
+
+The Samsung SPI controller is used to interface with various devices such as flash
+and display controllers using the SPI communication interface.
+
+Required SoC Specific Properties:
+
+- compatible: should be one of the following.
+    - samsung,s3c2443-spi: for s3c2443, s3c2416 and s3c2450 platforms
+    - samsung,s3c6410-spi: for s3c6410 platforms
+    - samsung,s5p6440-spi: for s5p6440 and s5p6450 platforms
+    - samsung,s5pv210-spi: for s5pv210 and s5pc110 platforms
+    - samsung,exynos4210-spi: for exynos4 and exynos5 platforms
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+  depends on the interrupt controller.
+
+- tx-dma-channel: The dma channel specifier for tx operations. The format of
+  the dma specifier depends on the dma controller.
+
+- rx-dma-channel: The dma channel specifier for rx operations. The format of
+  the dma specifier depends on the dma controller.
+
+Required Board Specific Properties:
+
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+- gpios: The gpio specifier for clock, mosi and miso interface lines (in the
+  order specified). The format of the gpio specifier depends on the gpio
+  controller.
+
+Optional Board Specific Properties:
+
+- samsung,spi-src-clk: If the spi controller includes a internal clock mux to
+  select the clock source for the spi bus clock, this property can be used to
+  indicate the clock to be used for driving the spi bus clock. If not specified,
+  the clock number 0 is used as default.
+
+- num-cs: Specifies the number of chip select lines supported. If
+  not specified, the default number of chip select lines is set to 1.
+
+SPI Controller specific data in SPI slave nodes:
+
+- The spi slave nodes should provide the following information which is required
+  by the spi controller.
+
+  - cs-gpio: A gpio specifier that specifies the gpio line used as
+    the slave select line by the spi controller. The format of the gpio
+    specifier depends on the gpio controller.
+
+  - samsung,spi-feedback-delay: The sampling phase shift to be applied on the
+    miso line (to account for any lag in the miso line). The following are the
+    valid values.
+
+      - 0: No phase shift.
+      - 1: 90 degree phase shift sampling.
+      - 2: 180 degree phase shift sampling.
+      - 3: 270 degree phase shift sampling.
+
+Aliases:
+
+- All the SPI controller nodes should be represented in the aliases node using
+  the following format 'spi{n}' where n is a unique number for the alias.
+
+
+Example:
+
+- SoC Specific Portion:
+
+	spi_0: spi@12d20000 {
+		compatible = "samsung,exynos4210-spi";
+		reg = <0x12d20000 0x100>;
+		interrupts = <0 66 0>;
+		tx-dma-channel = <&pdma0 5>;
+		rx-dma-channel = <&pdma0 4>;
+	};
+
+- Board Specific Portion:
+
+	spi_0: spi@12d20000 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		gpios = <&gpa2 4 2 3 0>,
+			<&gpa2 6 2 3 0>,
+			<&gpa2 7 2 3 0>;
+
+		w25q80bw@0 {
+			#address-cells = <1>;
+			#size-cells = <1>;
+			compatible = "w25x80";
+			reg = <0>;
+			spi-max-frequency = <10000>;
+
+			controller-data {
+				cs-gpio = <&gpa2 5 1 0 3>;
+				samsung,spi-feedback-delay = <0>;
+			};
+
+			partition@0 {
+				label = "U-Boot";
+				reg = <0x0 0x40000>;
+				read-only;
+			};
+
+			partition@40000 {
+				label = "Kernel";
+				reg = <0x40000 0xc0000>;
+			};
+		};
+	};
