Subject: [PATCH v20 04/41] xhci: export XHCI IMOD setting helper for interrupters
Date: Thu, 25 Apr 2024 14:50:48 -0700 [thread overview]
Message-ID: <20240425215125.29761-5-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240425215125.29761-1-quic_wcheng@quicinc.com>
Utilize the xhci_set_interrupter_moderation() API to set the IMOD value for
interrupters, so that secondary interrupts can also configure this
parameter when clients request for it.
