It allows to reset prevent_medium_removal flag and "eject" the image. This can be useful to free the drive from a hunging host or if the host continues to use the drive even after unmounting (Linux does this). It's also a bit like using an unfolded paperclip on an optical drive. Previously, the undocumented method of sending SIGUSR1 to a special "file-storage" kernel thread could be used for these purposes, but when using multiple storages there was no way to distinguish one from the other, so we had to send a signal to everyone.

The main issue this driver addresses is that a USB hub needs to be powered before it can be discovered. For discrete onboard hubs (an example for such a hub is the Realtek RTS5411) this is often solved by supplying the hub with an 'always-on' regulator, which is kind of a hack. Some onboard hubs may require further initialization steps, like changing the state of a GPIO or enabling a clock, which requires even more hacks. This driver creates a platform device representing the hub which performs the necessary initialization. Currently it only supports switching on a single regulator, support for multiple regulators or other actions can be added as needed. Different initialization sequences can be supported based on the compatible string. Besides performing the initialization the driver can be configured to power the hub off during system suspend. This can help to extend battery life on battery powered devices which have no requirements to keep the hub powered during suspend. The driver can also be configured to leave the hub powered when a wakeup capable USB device is connected when suspending, and power it off otherwise. Technically the driver consists of two drivers, the platform driver described above and a very thin USB driver that subclasses the generic driver. The purpose of this driver is to provide the platform driver with the USB devices corresponding to the hub(s) (a hub controller may provide multiple 'logical' hubs, e.g. one to support USB 2.0 and another for USB 3.x).

The event classes udc_log_ep and udc_log_req both declare: __dynamic_array(char, name, UDC_TRACE_STR_MAX) Which will reserve UDC_TRACE_STR_MAX bytes on the ring buffer for the event to write in name. It then uses snprintf() to write into that space. Assuming that the string being copied is nul terminated, it is better to just use the __string() helper. That way only the size of the string is saved into the ring buffer and not the max size (yes, the entire UDC_TRACE_STR_MAX is used in the trace event, and anything not used is just junk in the ring buffer). Worse, there's also meta data saved into the event that denotes where the string is stored in the event and also saves its size, which is always going to be UDC_TRACE_STR_MAX. Convert both to use the __string() and __assign_str() helpers that are for this kind of use case.

All of the clocks listed in the binding are always wired to the XHCI controller hardware blocks on all SoCs. The reason some clocks were made optional in the binding was to account for the fact that depending on the SoC, some of the clocks might be fixed (ie not controlled by software). Given that the devicetree should represent the hardware, make all clocks required in the binding. Subsequent patches will make the DTS changes to specify fixed-clocks for the clocks that aren't controllable. Signed-off-by:
