From 743fcce0a89e04dc511b4ea40eba8e3f7cec92d4 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sun, 2 Jun 2013 01:33:56 +0400 Subject: ehci-platform: add pre_setup() method to platform data Sometimes there is a need to initialize some non-standard registers mapped to the EHCI region before accessing the standard EHCI registers. Add pre_setup() method with 'struct usb_hcd *' parameter to be called just before ehci_setup() to the 'ehci-platform' driver's platform data for this purpose... While at it, add the missing incomplete declaration of 'struct platform_device' to ... The patch has been tested on the Marzen and BOCK-W boards.
