[PATCH v5 4/5] clk/exynos5260: add macros and documentation for exynos5260

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add macros which are used as Clock IDs in DT and clock file.
It also adds the documentation for the exynos5260 clocks.

+* Samsung Exynos5260 Clock Controller
+
+The Exynos5260 clock controller encapsulate all CMUs which are
+instantiaited independently from the device-tree. As a whole, these
+CMUs generates and supplies clocks to various controllers within
+the Exynos5260 SoC.
+
+Required Properties:
+
+- compatible: should be one of the following.
+	"exynos5260-clock-top"
+	"exynos5260-clock-peri"
+	"exynos5260-clock-egl"
+	"exynos5260-clock-kfc"
+	"exynos5260-clock-g2d"
+	"exynos5260-clock-mif"
+	"exynos5260-clock-mfc"
+	"exynos5260-clock-g3d"
+	"exynos5260-clock-fsys"
+	"exynos5260-clock-aud"
+	"exynos5260-clock-isp"
+	"exynos5260-clock-gscl"
+	"exynos5260-clock-disp"
+
+- 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 each controller. Each
+clock is assigned with a MACRO constant. These constants are defined in
+"dt-bindings/clk/exynos5260-clk.h". DT client nodes use this MACRO to
+specify the clock, which they want to consume.
+
+Example 1: An example of a clock controller node is listed below.
+
+	cmu_disp: clock-controller@0x14550000 {
+		compatible = "exynos5260-clock-disp";
+		reg = <0x14550000 0x10000>;
+		#clock-cells = <1>;
+	};
+
+Example 2: UART controller node that consumes the clock generated by the
+		peri clock controller. Refer to the standard clock bindings for
+		information about 'clocks' and 'clock-names' property.
+
+	serial@12C00000 {
+		compatible = "samsung,exynos4210-uart";
+		reg = <0x12C00000 0x100>;
+		interrupts = <0 146 0>;
+		clocks = <&clock_peri PERI_PCLK_UART0>, <&clock_peri PERI_SCLK_UART0>;
+		clock-names = "uart", "clk_uart_baud0";
+		status = "disabled";
+	};
