usb: mtu3: fix memory corruption in mtu3_debugfs_regset()

2020-12-07T14:26:18+00:00

This code is using the wrong sizeof() so it does not allocate enough
memory.  It allocates 32 bytes but 72 are required.  That will lead to
memory corruption.

usb: mtu3: constify struct debugfs_reg32

2020-05-14T09:42:53+00:00

mtu3_prb_regs is never changed and can therefore be made const.

This allows the compiler to put it in the text section instead of the
data section.

Before:
   text    data     bss     dec     hex filename
  19966    7120       0   27086    69ce drivers/usb/mtu3/mtu3_debugfs.o

After:
   text    data     bss     dec     hex filename
  20142    6992       0   27134    69fe drivers/usb/mtu3/mtu3_debugfs.o

usb: mtu3: register a USB Role Switch for dual role mode

2019-09-03T18:02:15+00:00

Because extcon is not allowed for new bindings, and the
dual role switch is supported by USB Role Switch,
especially for Type-C drivers, so register a USB Role
Switch to support the new way

Revert "usb: mtu3: fix up undefined reference to usb_debug_root"

2019-06-10T17:43:57+00:00

It's not needed after [1] is applied, because usb_debug_root is created
by usb common core but not usbcore now.

usb: mtu3: fix up undefined reference to usb_debug_root

2019-05-21T08:08:56+00:00

When CONFIG_USB is not set, and CONFIG_USB_GADGET is set,
there is an issue:

ld:
drivers/usb/mtu3/mtu3_debugfs.o: in function 'ssusb_debugfs_create_root':
mtu3_debugfs.c:(.text+0xba3): undefined reference to 'usb_debug_root'

usb_debug_root is only built when CONFIG_USB is enabled, so here drop it
and use NULL instead.

usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c

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

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

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.
