| 13 | This binding describes the ARC AXS10x boards custom IP-block which allows |
| 14 | to control reset signals of selected peripherals. For example DW GMAC, etc... |
| 15 | This block is controlled via memory-mapped register (AKA CREG) which |
| 16 | represents up-to 32 reset lines. |
| 17 | As of today only the following lines are used: |
| 18 | - DW GMAC - line 5 |
