From d4a8d46d9129fbb26b4c2d3143b1b0975a9b4ae4 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 6 Dec 2007 18:18:03 -0800 Subject: USB: gadget: pxa2xx_udc supports inverted vbus Some boards (like e.g. Tosa) invert the VBUS-detection signal: it's low when a host is supplying VBUS, and high otherwise. Allow specifying whether gpio_vbus value is inverted.
