| Binding for the AXS10x reset controller |
| |
| This binding describes the ARC AXS10x boards custom IP-block which allows |
| to control reset signals of selected peripherals. For example DW GMAC, etc... |
| This block is controlled via memory-mapped register (AKA CREG) which |
| represents up-to 32 reset lines. |
| |
| As of today only the following lines are used: |
| - DW GMAC - line 5 |
| |
| This binding uses the common reset binding[1]. |

| [1] Documentation/devicetree/bindings/reset/reset.txt |
| |
| Required properties: |
| - compatible: should be "snps,axs10x-reset". |
| - reg: should always contain pair address - length: for creg reset |
| bits register. |
| - #reset-cells: from common reset binding; Should always be set to 1. |
| |
| Example: |
| reset: reset-controller@11220 { |
| compatible = "snps,axs10x-reset"; |
| #reset-cells = <1>; |
| reg = <0x11220 0x4>; |
| }; |
| |
| Specifying reset lines connected to IP modules: |
| ethernet@.... { |
| .... |
| resets = <&reset 5>; |
| .... |
| }; |
