usb: misc: onboard_dev: add vdda support for Microchip USB2514This hub is powered by digital and analog 3V3 power rails, so providethe possibility to use different regulators for digital (vdd) and analog(vdda) power rails.Signed-off-by: Catalin Popescu Link: https://lore.kernel.org/r/20250213094338.1611389-3-catalin.popescu@leica-geosystems.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/onboard_usb_dev.h

908f61be - usb: misc: onboard_dev: extend platform data to add power on delay field

Sat, 07 Sep 2024 18:03:15 +0000

usb: misc: onboard_dev: extend platform data to add power on delay fieldIntroduce dedicated field 'power_on_delay_us' in onboard platform dataand update its delay for USB5744 configuration. Hub itself requires somedelay after reset to get to state where configuration data is going tobe accepted. Without delay upcoming support for configuration via SMBUSis reporting a failure on the first SMBus write.i2c 2-002d: error -ENXIO: BYPASS_UDC_SUSPEND bit configuration failedSimilar delay is likely also required for default configuration butbecause there is enough time (code execution) between reset and usageof the hub any issue is not visible but it doesn't mean delay shouldn'tbe reflected.Signed-off-by: Radhey Shyam Pandey Suggested-by: Matthias Kaehlcke Link: https://lore.kernel.org/r/1725732196-70975-2-git-send-email-radhey.shyam.pandey@amd.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/onboard_usb_dev.h

ef83531c - usb: misc: onboard_dev: add support for XMOS XVF3500

Mon, 25 Mar 2024 09:15:18 +0000

usb: misc: onboard_dev: add support for XMOS XVF3500The XMOS XVF3500 VocalFusion Voice Processor[1] is a low-latency, 32-bitmulticore controller for voice processing.This device requires a specific power sequence, which consists ofenabling 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 USB device,and it does not require any device-specific operations in the driver.[1] https://www.xmos.com/xvf3500/Acked-by: Matthias Kaehlcke Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240325-onboard_xvf3500-v8-8-29e3f9222922@wolfvision.netSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/onboard_usb_dev.h

dd84ac97 - usb: misc: onboard_dev: add support for non-hub devices

Mon, 25 Mar 2024 09:15:16 +0000

usb: misc: onboard_dev: add support for non-hub devicesMost of the functionality this driver provides can be used by non-hubdevices as well.To account for the hub-specific code, add a flag to the device datastructure and check its value for hub-specific code.The 'always_powered_in_supend' attribute is only available for hubdevices, keeping the driver's default behavior for non-hub devices (keepon in suspend).Acked-by: Matthias Kaehlcke Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240325-onboard_xvf3500-v8-6-29e3f9222922@wolfvision.netSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/onboard_usb_dev.h

31e7f6c0 - usb: misc: onboard_hub: rename to onboard_dev

Mon, 25 Mar 2024 09:15:12 +0000

usb: misc: onboard_hub: rename to onboard_devThis patch prepares onboad_hub to support non-hub devices by renamingthe driver files and their content, the headers and their references.The comments and descriptions have been slightly modified to keepcoherence and account for the specific cases that only affect onboardhubs (e.g. peer-hub).The "hub" variables in functions where "dev" (and similar names) variablesalready exist have been renamed to onboard_dev for clarity, which adds afew lines in cases where more than 80 characters are used.No new functionality has been added.Acked-by: Matthias Kaehlcke Signed-off-by: Javier Carrasco Link: https://lore.kernel.org/r/20240325-onboard_xvf3500-v8-2-29e3f9222922@wolfvision.netSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/misc/onboard_usb_dev.h
