usb: dwc3: create debugfs directory under usb root

2019-11-14T03:14:54+00:00

Now the USB gadget subsystem can use the USB debugfs root directory, so move dwc3's directory from the root of the debugfs filesystem into the root of usb Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/1573541519-28488-4-git-send-email-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman

usb: dwc3: debugfs: Print/set link state for peripheral mode

2018-11-26T07:06:31+00:00

Current implementation only prints/sets the link state for peripheral mode only. Check and prevent printing bogus link state if the current mode of operation is not peripheral. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

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

2018-11-26T07:06:31+00:00

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

usb: dwc3: debugfs: Dump internal LSP and ep registers

2018-11-26T07:06:31+00:00

To dump internal LSP and endpoint state debug registers, we must write to GDBGLSPMUX register. This patch correctly dump LSP and endpoint states from the debug registers. If the controller is in device mode, all LSP and endpoint state registers will be dumped via the debugfs attribute "lsp_dump". In host mode, the user has to write the LSP number to "lsp_dump" to dump a specific LSP selection.

usb: dwc3: debugfs: Print eps Tx/RxFIFO in bytes

TxFIFO and RxFIFO from GDBGFIFOSPACE are fifo depths in MDWIDTH. Convert them into bytes for easier read. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

usb: dwc3: debugfs: Properly name Tx/RxFIFO

The Tx/RxFIFO types in the GDBGFIFOSPACE.FIFO_QUEUE_SELECT are not queue. Properly rename them. Signed-off-by: Thinh Nguyen Signed-off-by: Felipe Balbi

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: 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.
