Kernel-4.18.0-80.el8_snps,axs10x-reset

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>;
….
};
