Please update the commit message, the onboard_hub driver no longer exists as such with the other patches of this series. > Once in normal operation, the XVF3500 registers itself as a USB device, > and it does not require any device-specific operations in the driver. > > [1] https://www.xmos.com/xvf3500/ > > Signed-off-by: Javier Carrasco <javier.carrasco@wolfvision.net> Acked-by: Matthias Kaehlcke <mka@chromium.org> > --- > drivers/usb/misc/onboard_usb_dev.c | 2 ++ > drivers/usb/misc/onboard_usb_dev.h | 8 ++++++++ > 2 files changed, 10 insertions(+) > > diff --git a/drivers/usb/misc/onboard_usb_dev.c b/drivers/usb/misc/onboard_usb_dev.c > index df0ed172c7ec..50f84c5278a2 100644 > --- a/drivers/usb/misc/onboard_usb_dev.c > +++ b/drivers/usb/misc/onboard_usb_dev.c > @@ -405,6 +405,7 @@ static struct platform_driver onboard_dev_driver = { > #define VENDOR_ID_REALTEK 0x0bda > #define VENDOR_ID_TI 0x0451 > #define VENDOR_ID_VIA 0x2109 > +#define VENDOR_ID_XMOS 0x20B1 > > /* > * Returns the onboard_dev platform device that is associated with the USB > @@ -497,6 +498,7 @@ static const struct usb_device_id onboard_dev_id_table[] = { > { USB_DEVICE(VENDOR_ID_TI, 0x8142) }, /* TI USB8041 2.0 */ > { USB_DEVICE(VENDOR_ID_VIA, 0x0817) }, /* VIA VL817 3.1 */ > { USB_DEVICE(VENDOR_ID_VIA, 0x2817) }, /* VIA VL817 2.0 */ > + { USB_DEVICE(VENDOR_ID_XMOS, 0x0013) }, /* XVF3500 */ nit: be a bit more specific? e.g. XVF3500 Voice Processor, or XMOS XVF3500 The other entries were implicitly hubs since this was the 'onboard_hub' driver. It wouldn't be a bad idea to add 'hub' to these entries in the patch that 'renames' the driver.

The XMOS XVF3500 VocalFusion Voice Processor[1] is a low-latency, 32-bit multicore controller for voice processing. This device 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. Such power sequence is already supported by the onboard_hub driver, and it can be reused for non-hub USB devices as well. Once in normal operation, the XVF3500 registers itself as a USB device, and it does not require any device-specific operations in the driver.
