Subject: [PATCH v2 4/9] usb: host: xhci-plat: add platform data support
Date: Sun, 24 May 2020 07:22:59 +0800
Message-ID: <20200523232304.23976-5-peter.chen@nxp.com> (raw)
In-Reply-To: <20200523232304.23976-1-peter.chen@nxp.com>

Some xhci hosts (eg dwc3 and cdns3) do not use OF to create
platform device, they create xhci-plat platform device runtime.
And these platforms may also have quirks, and the quirks could
be supplied by their parent device through platform data.
