usb: dwc3: fix up for role switch API change

usb: dwc3: Registering a role switch in the DRD code.

2020-03-15T09:30:32Z

The Type-C drivers use USB role switch API to inform the system about the negotiated data role, so registering a role switch in the DRD code in order to support platforms with USB Type-C connectors.

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: drd: Add support for DR detection through extcon

2018-11-26T07:06:32Z

Allow extcon device, found by name, to provide DR status for USB. This is needed, for example, in case of Intel Merrifield platform, where the Intel Basin Cove PMIC provides an extcon device to communicate the detected role. Note, that the "linux,extcon-name" property name is only for kernel internal use by X86/ACPI platform code and as such is not documented in the device tree bindings.
