Subject: [PATCH v21 04/39] usb: xhci: Allow for secondary interrupter to set IMOD
Date: Tue, 7 May 2024 12:50:41 -0700 [thread overview]
Message-ID: <20240507195116.9464-5-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240507195116.9464-1-quic_wcheng@quicinc.com>
When creating a secondary interrupter, add an argument for XHCI sideband
clients to specify an interrupt moderation value for the interrupter
context.
