Subject: [PATCH v18 18/41] usb: host: xhci-plat: Set XHCI max interrupters if property is present
Date: Tue, 27 Feb 2024 17:35:56 -0800 [thread overview]
Message-ID: <20240228013619.29758-19-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240228013619.29758-1-quic_wcheng@quicinc.com>
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.
