+* Samsung Exynos5260 Clock Controller
+
+Exynos5260 has 13 clock controllers which are instantiated
+independently from the device-tree. These clock controllers
+generate and supply clocks to various hardware blocks within
+the SoC.
+
+Each clock is assigned an identifier and client nodes can use
+this identifier to specify the clock which they consume. All

+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It
+is expected that they are defined using standard clock bindings
+with following clock-output-names:
+
+ - "fin_pll" - PLL input clock from XXTI
+ - "xrtcxti" - input clock from XRTCXTI
+ - "ioclk_pcm_extclk" - pcm external operation clock
+ - "ioclk_spdif_extclk" - spdif external operation clock
+ - "ioclk_i2s_cdclk" - i2s0 codec clock
+
+Phy clocks:
+
+There are several clocks which are generated by specific PHYs.
+These clocks are fed into the clock controller and then routed to
+the hardware blocks. These clocks are defined as fixed clocks in the
+driver with following names:
+
+ - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
+ - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2

+* Samsung S3C2443 Clock Controller
+
+The S3C2443 clock controller generates and supplies clock to various controllers
+within the SoC. The clock binding described here is applicable to all SoCs in
+the s3c24x family starting with the s3c2443.
+
+Required Properties:
+
+- compatible: should be one of the following.
+ - "samsung,s3c2416-clock" - controller compatible with S3C2416 SoC.
+ - "samsung,s3c2443-clock" - controller compatible with S3C2443 SoC.
+ - "samsung,s3c2450-clock" - controller compatible with S3C2450 SoC.
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Some of the clocks are available only
+on a particular SoC.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/s3c2443.h header and can be used in device
+tree sources.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xti" - crystal input - required,
+ - "ext" - external clock source - optional,
+ - "ext_i2s" - external I2S clock - optional,
+ - "ext_uart" - external uart clock - optional,
+
+Example: Clock controller node:
+
+ clocks: clock-controller@4c000000 {
+ compatible = "samsung,s3c2416-clock";
+ reg = <0x4c000000 0x40>;
+ #clock-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller (refer to the standard clock bindings for information about
+ "clocks" and "clock-names" properties):

+ compatible = "samsung,s3c2440-uart";
+ reg = <0x50004000 0x4000>;
+ interrupts = <1 23 3 4>, <1 23 4 4>;
+ clock-names = "uart", "clk_uart_baud2",
+ "clk_uart_baud3";
+ clocks = <&clocks PCLK_UART0>, <&clocks PCLK_UART0>,
+ <&clocks SCLK_UART>;
+ status = "disabled";

+* Device tree bindings for Texas Instruments keystone pll controller
+
+The main pll controller used to drive theC66x CorePacs, the switch fabric,
+and a majority of the peripheral clocks (all but the ARM CorePacs, DDR3 and
+the NETCP modules) requires a PLL Controller to manage the various clock
+divisions, gating, and synchronization.
+
+Required properties:
+
+- compatible: "ti,keystone-pllctrl", "syscon"
+
+- reg: contains offset/length value for pll controller
+ registers space.
+
+Example:
+
+pllctrl: pll-controller@0x02310000 {
+ compatible = "ti,keystone-pllctrl", "syscon";
+ reg = <0x02310000 0x200>;
+};
