Subject: [PATCH 01/10] usb: host: xhci-plat: add platform data support
Date: Fri, 18 Sep 2020 16:17:43 +0300 [thread overview]
Message-ID: <20200918131752.16488-2-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20200918131752.16488-1-mathias.nyman@linux.intel.com>
From: Peter Chen <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.
