1 * Samsung Exynos7 Clock Controller
3 Exynos7 clock controller has various blocks which are instantiated
4 independently from the device-tree. These clock controllers
5 generate and supply clocks to various hardware blocks within
8 Each clock is assigned an identifier and client nodes can use
9 this identifier to specify the clock which they consume. All
10 available clocks are defined as preprocessor macros in
11 dt-bindings/clock/exynos7-clk.h header and can be used in
16 There are several clocks that are generated outside the SoC. It
17 is expected that they are defined using standard clock bindings
18 with following clock-output-names:
20 - "fin_pll" - PLL input clock from XXTI
22 Required Properties for Clock Controller:
24 - compatible: clock controllers will use one of the following
25 compatible strings to indicate the clock controller
28 - "samsung,exynos7-clock-topc"
29 - "samsung,exynos7-clock-top0"
30 - "samsung,exynos7-clock-top1"
31 - "samsung,exynos7-clock-ccore"
32 - "samsung,exynos7-clock-peric0"
33 - "samsung,exynos7-clock-peric1"
34 - "samsung,exynos7-clock-peris"
35 - "samsung,exynos7-clock-fsys0"
36 - "samsung,exynos7-clock-fsys1"
37 - "samsung,exynos7-clock-mscl"
38 - "samsung,exynos7-clock-aud"
40 - reg: physical base address of the controller and the length of
43 - #clock-cells: should be 1.
45 - clocks: list of clock identifiers which are fed as the input to
46 the given clock controller. Please refer the next section to
47 find the input clocks for a given controller.
49 - clock-names: list of names of clocks which are fed as the input
50 to the given clock controller.
