usb: dwc3: Remove kernel doc annotation where it's not needed

2020-03-15T09:08:53Z

The main comment in the file mistakenly marked with kernel doc annotation which makes the parser unhappy: .../dwc3/host.c:16: warning: Function parameter or member 'dwc' not described in 'dwc3_host_get_irq' Drop kernel doc annotation from host.c module.

usb: dwc3: Add ACPI support for xHCI ports

2020-03-15T09:08:49Z

The ACPI companion of the adapter has to be set for xHCI controller code to read and attach the ports described in the ACPI table. Use ACPI_COMPANION_SET macro to set this. Signed-off-by: Andy Shevchenko Signed-off-by: Felipe Balbi

usb: dwc3: use proper initializers for property entries

2020-01-09T09:28:52Z

We should not be reaching into property entries and initialize them by hand, but rather use proper initializer macros. This way we can alter internal representation of property entries with no visible changes to their users.

usb: dwc3: Remove dev_err() on platform_get_irq() failure

2019-10-07T10:52:44Z

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()"), platform_get_irq() will call dev_err() itself on failure, so there is no need for the driver to also do this.

usb: dwc3: Switch to platform_get_irq_byname_optional()

2019-10-07T10:52:44Z

The dwc3 code to get the "peripheral" / "host" / "otg" IRQ first tries platform_get_irq_byname() and then falls back to the IRQ at index 0 if the platform_get_irq_byname(). In this case we do not want platform_get_irq_byname() to print an error on failure, so switch to platform_get_irq_byname_optional() instead which does not print an error.

usb: dwc3: remove generic PHYs forwarding for XHCI device

2019-08-09T10:37:05Z

Commit 08f871a3aca2 ("usb: dwc3: host: convey the PHYs to xhci") added forwarding of the generic PHYs from DWC3 core to the instantiated XHCI-plat device. However XHCI(-plat) driver never gained support for generic PHYs, thus the lookup added by that commit is never used. In meantime the commit d64ff406e51e ("usb: dwc3: use bus->sysdev for DMA configuration") incorrectly changed the device used for creating lookup, making the lookup useless and generic PHYs inaccessible from XHCI device. However since commit 178a0bce05cb ("usb: core: hcd: integrate the PHY wrapper into the HCD core") USB HCD already handles generic PHYs acquired from the HCD's 'sysdev', which in this case is DWC3 core device. This means that creating any custom lookup entries for XHCI driver is no longer needed and can be simply removed. Signed-off-by: Marek Szyprowski Signed-off-by: Felipe Balbi

USB: dwc3: Remove redundant license text

2017-11-07T14:45:01Z

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/

2017-11-04T10:48:02Z

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: host: pass quirk-broken-port-ped property for known broken revisions

2017-01-26T09:17:37Z

dwc3 revisions <=3.00a have a limitation where Port Disable command doesn't work. Set the quirk-broken-port-ped property for such controllers so XHCI core can do the necessary workaround.
