From 294f78ec493e69b55bcba566d4fe264d041aba8d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Heiko=20St=C3=BCbner?= Date: Sun, 8 Jan 2012 21:58:28 +0100 Subject: [PATCH] usb: s3c-hsudc: add basic runtime_pm calls This will enable the system to check for activity of the usb gadget and also in a later patch to control the usbphy power-domain. When handling the power domain there, it will be possible to remove another reference to architecture code.
