usb: mtu3: mtu3_debug: remove an unused struct member

2020-12-04T15:49:06+00:00

The "nregs" member is not used.  The code uses the "regset.nregs"
struct member instead.

usb: mtu3: mtu3_debug: Add forward declaration of 'struct ssusb_mtk'

2020-07-09T14:46:57+00:00

Without it, the build system complains that it was declared inside
the parameter list.

Fixes the following W=1 kernel build warning(s):

 In file included from drivers/usb/mtu3/mtu3_trace.c:11:
 drivers/usb/mtu3/mtu3_debug.h:29:36: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration

USB: mtu3: Use the correct style for SPDX License Identifier

2020-04-16T12:32:48+00:00

This patch corrects the SPDX License Identifier style in
header files related to MediaTek USB3 Dual Role controller.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Changes made by using a script provided by Joe Perches here:

usb: mtu3: add debugfs interface files

2019-03-26T07:40:14+00:00

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.
