1Binding for simple memory mapped io fixed-rate clock sources. 2The driver reads a clock frequency value from a single 32-bit memory mapped 3I/O register and registers it as a fixed rate clock. 4 5It was designed for test systems, like FPGA, not for complete, finished SoCs. 6 7This binding uses the common clock binding[1]. 8 9[1] Documentation/devicetree/bindings/clock/clock-bindings.txt 10 11Required properties: 12- compatible : shall be "fixed-mmio-clock". 13- #clock-cells : from common clock binding; shall be set to 0. 14- reg : Address and length of the clock value register set. 15 16Optional properties: 17- clock-output-names : From common clock binding. 18 19Example: 20sysclock: sysclock@fd020004 { 21 #clock-cells = <0>; 22 compatible = "fixed-mmio-clock"; 23 reg = <0xfd020004 0x4>; 24}; 25
