-* 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,s5pv210-spi: for s5pv210 and s5pc110 platforms
-    - samsung,exynos5433-spi: for exynos5433 compatible controllers
-    - samsung,exynos7-spi: for exynos7 platforms <DEPRECATED>
-
-- 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.
-
-- dmas : Two or more DMA channel specifiers following the convention outlined
-  in bindings/dma/dma.txt
-
-- dma-names: Names for the dma channels. There must be at least one channel
-  named "tx" for transmit and named "rx" for receive.
-
-- clocks: specifies the clock IDs provided to the SPI controller; they are
-  required for interacting with the controller itself, for synchronizing the bus
-  and as I/O clock (the latter is required by exynos5433 and exynos7).
-
-- clock-names: string names of the clocks in the 'clocks' property; for all the
-  the devices the names must be "spi", "spi_busclkN" (where N is determined by
-  "samsung,spi-src-clk"), while Exynos5433 should specify a third clock
-  "spi_ioclk" for the I/O clock.
-
-Required Board Specific Properties:
-
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-
-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.
-
-- cs-gpios: should specify GPIOs used for chipselects (see spi-bus.txt)
-
-- no-cs-readback: the CS line is disconnected, therefore the device should not
-  operate based on CS signalling.
-
-SPI Controller specific data in SPI slave nodes:
-
-- The spi slave nodes should provide the following information which is required
-  by the spi 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:
-
