+Exynos4412 SoC contains some additional clocks for FIMC-ISP (Camera ISP)
+subsystem. Registers for those clocks are located in the ISP power domain.
+Because those registers are also located in a different memory region than
+the main clock controller, a separate clock controller has to be defined for
+handling them.
+
+Required Properties:
+
+- compatible: should be "samsung,exynos4412-isp-clock".
+
+- reg: physical base address of the ISP clock controller and length of memory
+ mapped region.
+
+- #clock-cells: should be 1.
+
+- clocks: list of the clock controller input clock identifiers,
+ from common clock bindings, should point to CLK_ACLK200 and
+ CLK_ACLK400_MCUISP clocks from the main clock controller.
+
+- clock-names: list of the clock controller input clock names,
+ as described in clock-bindings.txt, should be "aclk200" and
+ "aclk400_mcuisp".
+
+- power-domains: a phandle to ISP power domain node as described by
