From 16297cfb2a20c9d89834cd9e31edac5184a777a1 Mon Sep 17 00:00:00 2001 From: Mateusz Zalega Date: Fri, 4 Oct 2013 19:22:26 +0200 Subject: [PATCH] usb: new board-specific USB init interface This commit unifies board-specific USB initialization implementations under one symbol (usb_board_init), declaration of which is available in usb.h. New API allows selective initialization of USB controllers whenever needed.
