usb: dwc3: debugfs: Properly print/set link state for HS

2019-12-13T07:51:45+00:00

[ Upstream commit 0d36dede457873404becd7c9cb9d0f2bcfd0dcd9 ] Highspeed device and below has different state names than superspeed and higher. Add proper checks and printouts of link states for highspeed and below. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi Signed-off-by: Sasha Levin

USB: dwc3: no need to check return value of debugfs_create functions

2018-05-31T10:54:22+00:00

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Cc: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: dwc3: Dump LSP and BMU debug info

usb: dwc3: debugfs: Re-use DEFINE_SHOW_ATTRIBUTE() macro

2018-03-08T13:12:00+00:00

...instead of open coding file operations followed by custom ->open() callbacks per each attribute. Reviewed-by: Andy Shevchenko Signed-off-by: Felipe Balbi

USB: dwc3: Remove redundant license text

2017-11-07T14:45:01+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: dwc3: debugfs: slightly improve output of trb_ring

2017-06-02T08:22:28+00:00

Instead of printing out enqueue and dequeue pointer value as a header to the output, let's mark the TRBs in question with 'E' and 'D'. The output looks slightly easier to read. Signed-off-by: Felipe Balbi

usb: dwc3: core: make dwc3_set_mode() work properly

2017-04-11T07:58:30+00:00

We can't have both Host and Peripheral roles active at the same time because of one detail on DWC3: it shares the same memory area for both Host and Peripheral registers. When swapping roles we must reinitialize the new role every time. Let's make sure this works for our debugfs interface. Signed-off-by: Roger Quadros Signed-off-by: Felipe Balbi

usb: dwc3: debugfs: remove unnecessary | operator

2017-04-11T07:58:30+00:00

Each role is mutually exclusive, the | operator is unnecessary. Remove it. Signed-off-by: Roger Quadros Signed-off-by: Felipe Balbi

usb: dwc3: expose dwc3_trb_type_string()

2017-04-11T07:58:26+00:00

That helper can be used from our tracepoint interface with very minor edits. Let's do so. Signed-off-by: Felipe Balbi
