    Subject[RFC PATCH v2 14/22] dt-bindings: usb: dwc3: Add snps,num-hc-interrupters definition
    Date
    Add a new definition for specifying how many XHCI secondary interrupters
    can be allocated. XHCI in general can potentially support up to 1024
    interrupters, which some uses may want to limit depending on how many
    users utilize the interrupters.
