Binding for simple memory mapped io fixed-rate clock sources. |
|
The driver reads a clock frequency value from a single 32-bit memory mapped |
|
I/O register and registers it as a fixed rate clock. |
|
|
|
It was designed for test systems, like FPGA, not for complete, finished SoCs. |
|
|
|
This binding uses the common clock binding[1]. |

|
|
|
Required properties: |
|
- compatible : shall be "fixed-mmio-clock". |
|
- #clock-cells : from common clock binding; shall be set to 0. |
|
- reg : Address and length of the clock value register set. |
|
|
|
Optional properties: |
|
- clock-output-names : From common clock binding. |
|
|
|
Example: |
|
sysclock: sysclock@fd020004 { |
|
#clock-cells = <0>; |
|
compatible = "fixed-mmio-clock"; |
|
reg = <0xfd020004 0x4>; |
|
};
