Hi! This series adds support for the Cypress HX3 USB 3.0 family (2/3). For now, it just contains the USB-related aspects and ignores the option to connect it via i2c (3/3). As the HX3 family operates with two power supplies, multiple power supply support is implemented (1/3). Thanks & best regards, Benjamin --- Changes in v4: - 1/3: set num_supplies=1 for the existing hubs - 1/3: drop duplicate num_supplies in onboard_hub struct - 1/3: clarify connection between supply_names and MAX_SUPPLIES - Link to v3: https://lore.kernel.org/r/20230620-hx3-v3-0-2acbc03ca949@skidata.com Changes in v3: - 1/3: fix nits mentioned by Matthias - Link to v2: https://lore.kernel.org/r/20230620-hx3-v2-0-76a53434c713@skidata.com Changes in v2: - don't re-order by VID/PID (thanks to Matthias) - 1/3: replace (err != 0) with (err) - Link to v1: https://lore.kernel.org/r/20230620-hx3-v1-0-3a649b34c85b@skidata.com --- Benjamin Bara (3): usb: misc: onboard-hub: support multiple power supplies usb: misc: onboard-hub: add support for Cypress HX3 USB 3.0 family dt-bindings: usb: Add binding for Cypress HX3 USB 3.0 family .../devicetree/bindings/usb/cypress,hx3.yaml | 77 ++++++++++++++++++++++ drivers/usb/misc/onboard_usb_hub.c | 45 ++++++++++--- drivers/usb/misc/onboard_usb_hub.h | 14 ++++ 3 files changed, 128 insertions(+), 8 deletions(-) --- base-commit: 45a3e24f65e90a047bef86f927ebdc4c710edaa1 change-id: 20230620-hx3-cb935b4fdd76 Best regards,
