From 46034a999c07fff750deb44d1bf5161e8c63646e Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Fri, 18 Sep 2020 16:17:43 +0300 Subject: usb: host: xhci-plat: add platform data support 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.
