[PATCH v18 18/41] usb: host: xhci-plat: Set XHCI max interrupters if property is present

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Some platforms may want to limit the number of XHCI interrupters allocated.
This is passed to xhci-plat as a device property.  Ensure that this is read
and the max_interrupters field is set.
