Chunfeng Yun	4aab6ad24a	usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c ... Due to the separated debugfs files are added, move vbus and mode debugfs interfaces related with dual-role switch from mtu3_dr.c into mtu3_debugfs.c Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2019-03-26 16:40:14 +09:00
Chunfeng Yun	ae07809255	usb: mtu3: add debugfs interface files ... This adds more debugfs consumers. The debugfs entries read some important registers, fifo status, QMU ring, endpoint status, and IPPC probe interface to get internal status. With these entries, users can check the registers, endpoint and GPD used during run time.
