Subject: [PATCH v5 3/3] usb: dwc3: Pass quirk as platform data
Date: Fri, 16 Oct 2020 18:35:43 +0530
Message-ID: <ea34abd77a34e9587fb49868050e152094cf1403.1602853270.git.joglekar@synopsys.com> (raw)
In-Reply-To: <cover.1602853270.git.joglekar@synopsys.com>

This commit adds the platform device data to setup
the XHCI_SG_TRB_CACHE_SIZE_QUIRK quirk. DWC3 hosts
which are PCI devices does not use OF to create platform device
but create xhci-plat platform device at runtime. So
this patch allows parent device to supply the quirk
through platform data.
