Dspi-samsung.txt1 * Samsung SPI Controller
3 The Samsung SPI controller is used to interface with various devices such as flash
4 and display controllers using the SPI communication interface.
8 - compatible: should be one of the following.
9 - samsung,s3c2443-spi: for s3c2443, s3c2416 and s3c2450 platforms
10 - samsung,s3c6410-spi: for s3c6410 platforms
11 - samsung,s5pv210-spi: for s5pv210 and s5pc110 platforms
12 - samsung,exynos5433-spi: for exynos5433 compatible controllers
13 - samsung,exynos7-spi: for exynos7 platforms <DEPRECATED>
15 - reg: physical base address of the controller and length of memory mapped
