Subject: [PATCH v5 4/9] usb: host: xhci-plat: add platform data support
Date: Tue, 7 Jul 2020 15:49:36 +0800 [thread overview]
Message-ID: <20200707074941.28078-5-peter.chen@nxp.com> (raw)
In-Reply-To: <20200707074941.28078-1-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.
Acked-by: Mathias Nyman <mathias.nyman@linux.intel.com>
