+			STi ARM Linux Overview
+			==========================
+
+Introduction
+------------
+
+  The ST Microelectronics Multimedia and Application Processors range of
+  CortexA9 System-on-Chip are supported by the 'STi' platform of
+  ARM Linux. Currently STiH415, STiH416 SOCs are supported with both
+  B2000 and B2020 Reference boards.
+
+
+  configuration
+  -------------
+
+  A generic configuration is provided for both STiH415/416, and can be used as the
+  default by
+	make stih41x_defconfig
+
+  Layout
+  ------
+  All the files for multiple machine families (STiH415, STiH416, and STiG125)
+  are located in the platform code contained in arch/arm/mach-sti
+
+  There is a generic board board-dt.c in the mach folder which support
+  Flattened Device Tree, which means, It works with any compatible board with
+  Device Trees.

+* Samsung Exynos5420 Clock Controller
+
+The Exynos5420 clock controller generates and supplies clock to various
+controllers within the Exynos5420 SoC.
+
+Required Properties:
+
+- comptible: should be one of the following.
+  - "samsung,exynos5420-clock" - controller compatible with Exynos5420 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- #clock-cells: should be 1.
+
+The following is the list of clocks generated by the controller. Each clock is
+assigned an identifier and client nodes use this identifier to specify the
+clock which they consume.

+
