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
