From 0e1f991efb85520590fba6ad7955116a7bd499d4 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 4 May 2015 14:09:23 -0300 Subject: [PATCH] mx6cuboxi: Skip usb initialization when booting without HDMI Starting USB initialization is useful for those who use Cuboxi/Hummingboard with HDMI and USB keyboard.
