Subject: [PATCH v8 0/8] usb: misc: onboard_hub: add support for XMOS
XVF3500
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.
