usb: ulpi: Fix debugfs directory leak
commit 3caf2b2ad7334ef35f55b95f3e1b138c6f77b368 upstream.

usb: ulpi: Fix debugfs directory leak
commit 3caf2b2ad7334ef35f55b95f3e1b138c6f77b368 upstream.
The ULPI per-device debugfs root is named after the ulpi device's parent, but ulpi_unregister_interface tries to remove a debugfs directory named after the ulpi device itself. This results in the directory sticking around and preventing subsequent (deferred) probes from succeeding. Change the directory name to match the ulpi device.

usb: ulpi: defer ulpi_register on ulpi_read_id timeout
Since commit 0f0101719138 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present") Dual Role support on Intel Merrifield platform broke due to rearranging the call to dwc3_get_extcon().
It appears to be caused by ulpi_read_id() on the first test write failing with -ETIMEDOUT. Currently ulpi_read_id() expects to discover the phy via DT when the test write fails and returns 0 in that case, even if DT does not provide the phy. As a result usb probe completes without phy.
Make ulpi_read_id() return -ETIMEDOUT to its user if the first test write fails. The user should then handle it appropriately. A follow up patch will make dwc3_core_init() set -EPROBE_DEFER in this case and bail out.

usb: ulpi: Add debugfs support
This adds a debugfs file for ULPI devices which contains a dump of their registers. This is useful for debugging basic connectivity problems. The file is created in ulpi_register because many devices will never have a driver bound (as they are managed in hardware by the USB controller device).
The root directory of this subsystem is created before we register the bus to ensure that devices can always create their directories.

The Qualcomm USB HS PHY driver that is enabled by CONFIG_PHY_QCOM_USB_HS, registers a ulpi_driver but this driver does not provide an 'id_table', so when ulpi_match() is called on the Tegra20 Ventana platform, it crashes when attempting to deference the id_table pointer which is not valid. The Qualcomm USB HS PHY driver uses device-tree for matching the ULPI driver with the device and so fix this crash by using device-tree for matching if the id_table is not valid.

bus: Make remove callback return void
The driver core ignores the return value of this callback because there is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away.
With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

Fix bus-node lookup during registration, which ended up searching the whole device tree depth-first starting at the parent (or grand parent) rather than just matching on its children.
To make things worse, the parent (or grand-parent) node could end being prematurely freed as well.

USB: common: Remove redundant license text
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/
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: ulpi: Support device discovery via DT
The qcom HSIC ULPI phy doesn't have any bits set in the vendor or product ID registers. This makes it impossible to make a ULPI driver match against the ID registers. Add support to discover the ULPI phys via DT help alleviate this problem. In the DT case, we'll look for a ULPI bus node underneath the device registering the ULPI viewport (or the parent of that device to support chipidea's device layout) and then match up the phy node underneath that with the ULPI device that's created.
The side benefit of this is that we can use standard properties in the phy node like clks, regulators, gpios, etc. because we don't have firmware like ACPI to turn these things on for us. And we can use the DT phy binding to point our phy consumer to the phy provider.
The ULPI bus code supports native enumeration by reading the vendor ID and product ID registers at device creation time, but we can't be certain that those register reads will succeed if the phy is not powered up. To avoid any problems with reading the ID registers before the phy is powered we fallback to DT matching when the ID reads fail.
If the ULPI spec had some generic power sequencing for these registers we could put that into the ULPI bus layer and power up the device before reading the ID registers. Unfortunately this doesn't exist and the power sequence is usually device specific. By having the device matched up with DT we can avoid this problem.
