| * MSM Perfmap interface for performance monitors | |
| Perfmap provides mapping of the base address for performance monitors and | |
| allows user-space to access it via mmap call. It create a character device | |
| driver which is accessed from user-space. | |
| The required nodes for Perfmap are: | |
| - compatible: "qcom,perfmap" | |
| - reg: base address and size of mapped area | |
| Example: | |
| qcom,perfmap@0xfc330000 { | |
| compatible = "qcom,perfmap"; | |
| reg = <0xfc330000 0x3000>; | |
| }; |
