From 6084f1bf0c51a99cbba612ee90a4607cffb8b042 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 24 Nov 2008 12:00:01 -0800 Subject: USB: otg: gpio_vbus transceiver stub gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.
