-
This binding describes the ARC AXS10x boards custom IP-block which allows
4
-
to control reset signals of selected peripherals. For example DW GMAC, etc...
5
-
This block is controlled via memory-mapped register (AKA CREG) which
6

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].
