Note: This series could not be completely applied due to conflicts upstream (TI TUSB8020 was added), and a rebase to the next -rc1 was suggested. The series is therefore identical to the previous version (v7), but taking into account the new hub. The first patch of the series has already been applied and it is not included anymore. This series adds support for the XMOS XVF3500 VocalFusion Voice Processor[1], a low-latency, 32-bit multicore controller for voice processing. The XVF3500 requires a specific power sequence, which consists of enabling the regulators that control the 3V3 and 1V0 device supplies, and a reset de-assertion after a delay of at least 100ns. Once in normal operation, the XVF3500 registers itself as a regular USB device and no device-specific management is required. The power management provided by onboard_usb_hub is not specific for hubs and any other USB device with the same power sequence could profit from that driver, provided that the device does not have any specific requirements beyond the power management. To account for non-hub devices, the driver has been renamed and an extra flag has been added to identify hubs and provide their specific functionality. Support for device-specific power suply names has also been added, keeping generic names for already supported devices to keep backwards compatibility. The references to onboard_usb_hub in the core and config files have been updated as well. The diff is way much bulkier than the actual code addition because of the file renaming, so in order to ease reviews and catch hub-specific code that might still affect non-hub devices, the complete renaming was moved to a single commit. This series has been tested with a Rockchip-based SoC and an XMOS XVF3500-FB167-C.
