Lots of little things in here, nothing major, just constant improvements, updates, and new features. Highlights are: - new USB power supply driver support. These changes did touch outside of drivers/usb/ but got acks from the relevant mantainers for them. - dts file updates and conversions - string function conversions into "safer" ones - new device quirks - xhci driver updates - usb gadget driver minor fixes - typec driver additions and updates - small number of thunderbolt driver changes - dwc3 driver updates and additions of new hardware support - other minor driver updates All of these have been in the linux-next tree for a while with no reported issues" * tag 'usb-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (176 commits) usb: dwc3: starfive: Add JHB100 USB 2.0 DRD controller dt-bindings: usb: dwc3: add support for StarFive JHB100 dt-bindings: usb: atmel,at91sam9rl-udc: convert to DT schema dt-bindings: usb: atmel,at91rm9200-udc: convert to DT schema dt-bindings: usb: generic-ehci: fix schema structure and add at91sam9g45 constraints dt-bindings: usb: generic-ohci: add AT91RM9200 OHCI binding support arm: dts: at91: remove unused #address-cells/#size-cells from sam9x60 udc node drivers/usb/host: Fix spelling error 'seperate' -> 'separate' usbip: tools: add hint when no exported devices are found USB: serial: iuu_phoenix: fix iuutool author name usb: gadget: f_ncm: validate minimum block_len in ncm_unwrap_ntb() usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete() usb: gadget: f_hid: Add missing error code usb: typec: cros_ec_ucsi: Load driver from OF and ACPI definitions dt-bindings: chrome: Add cros-ec-ucsi compatibility to typec binding USB: of: Simplify with scoped for each OF child loop usbip: validate number_of_packets in usbip_pack_ret_submit() usb: gadget: renesas_usb3: validate endpoint index in standard request handlers usb: core: config: reverse the size check of the SSP isoc endpoint descriptor usb: typec: ucsi: Set usb mode on partner change ... 2026-03-30T14:58:33+00:00 Amit Sunil Dhamne amitsd@google.com 2026-03-25T22:22:26+00:00 urn:sha1:70d7dd27f6dc9bada652c3a84ba7e6688a96f8db Add support for MAX77759 battery charger driver. This is a 4A 1-Cell Li+/LiPoly dual input switch mode charger. While the device can support USB & wireless charger inputs, this implementation only supports USB input. This implementation supports both buck and boost modes.

That also avoids non-trivial rebasing of the above series. Changes besides that: Replace the custom property by a standard one and do not use megaohms for the current sense resistor.
