In order to help debug, this series add more debugfs consumers, introduce a few initial tracepoints; And support new features introduced by USB3 Gen2 ISOC: 1. TXCSR/RXCSR registers are adjusted to support greater MULT and MAX_PKT 2. QMU format is also improved last, some small problems are fixed. Chunfeng Yun (11): usb: mtu3: check return value of devm_extcon_register_notifier() usb: mtu3: print useful information also for device and host modes usb: mtu3: remove unnecessary local variable @req usb: mtu3: rebuild the code of getting vbus regulator usb: mtu3: fix transfer error of USB3 Gen2 isoc usb: mtu3: rebuild qmu_gpd struct to prepare to support new QMU format usb: mtu3: supports new QMU format usb: mtu3: add debugfs interface files usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c usb: mtu3: add tracepoints to help debug usb: mtu3: add a function to switch mailbox state to string drivers/usb/mtu3/Makefile | 11 + drivers/usb/mtu3/mtu3.h | 57 ++- drivers/usb/mtu3/mtu3_core.c | 27 +- drivers/usb/mtu3/mtu3_debug.h | 50 +++ drivers/usb/mtu3/mtu3_debugfs.c | 539 +++++++++++++++++++++++++++++ drivers/usb/mtu3/mtu3_dr.c | 156 ++------- drivers/usb/mtu3/mtu3_dr.h | 4 + drivers/usb/mtu3/mtu3_gadget.c | 20 +- drivers/usb/mtu3/mtu3_gadget_ep0.c | 4 + drivers/usb/mtu3/mtu3_hw_regs.h | 48 ++- drivers/usb/mtu3/mtu3_plat.c | 28 +- drivers/usb/mtu3/mtu3_qmu.c | 118 ++++--- drivers/usb/mtu3/mtu3_qmu.h | 1 + drivers/usb/mtu3/mtu3_trace.c | 23 ++ drivers/usb/mtu3/mtu3_trace.h | 279 +++++++++++++++ 15 files changed, 1146 insertions(+), 219 deletions(-) create mode 100644 drivers/usb/mtu3/mtu3_debug.h create mode 100644 drivers/usb/mtu3/mtu3_debugfs.c create mode 100644 drivers/usb/mtu3/mtu3_trace.c create mode 100644 drivers/usb/mtu3/mtu3_trace.h -- 2.20.1
