usb: dwc2: Replace uint_t types with u

2025-06-02T07:57:43Z

Updates all instances of uint8_t, uint16_t, and uint32_t to u8, u16, and u32 respectively, ensuring consistent use of kernel-preferred types and resolving checkpatch.pl warnings.

usb: dwc2: Unify flush and reset logic with v4.20a support

2025-06-02T07:57:43Z

This patch merges flush and reset logic for both host and gadget code into a common set of functions, reducing duplication. It also adds support for the updated reset logic to compatible with core version since v4.20a. This patch mainly refers to the patch in the kernel. link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=65dc2e725286106f99c6f6b78e3d9c52c15f3a9c Signed-off-by: Kongyang Liu Tested-by: Peter Robinson Signed-off-by: Junhui Liu Reviewed-by: Mattijs Korpershoek Reviewed-by: Marek Vasut Link: https://lore.kernel.org/r/20250110-dwc2-dev-v4-7-987f4fd6f8b2@pigmoral.tech Signed-off-by: Mattijs Korpershoek

usb: dwc2: Extract macro definitions to common header

2025-06-02T07:57:25Z

Some macros are shared between host and gadget code, causing duplicated definitions. Move DWC2 macro definitions from host and gadget code into a common header to reduce duplication.

usb: dwc2: Align macros with Linux kernel definitions

2025-06-02T07:57:25Z

Update the DWC2 macros to match those used in the Linux kernel, making it easier to synchronize updates with kernel. Also removed some unused macros to cleanup the code.

usb: dwc2: Fix HBstLen setting for external DMA mode

2025-06-02T07:57:25Z

The loop used to calculate HBstLen for extern DMA mode does not produce the correct result according to the datasheet [1]. Replacing that loop with a direct calculation using LOG2 to correctly assign the burst length in the GAHBCFG register for external DMA mode.

usb: dwc2: Fix incorrect ULPI_UTMI_SEL bit setting

2025-06-02T07:57:25Z

The ULPI_UTMI_SEL bit in the DWC2 driver was set incorrectly. According to the datasheet [1], this bit should be set to 0 for UTMI interface and 1 for ULPI interface. The existing code had this logic reversed, causing the interface selection to be incorrect. This commit corrects the ULPI_UTMI_SEL bit setting to match the datasheet's description. Referencing the kernel's code [2] also confirms this fix.

usb: ulpi: Clean up how we enable support

2025-05-25T13:44:13Z

The way we enable ULPI support today isn't something that should work. The "optional" keyword in a choice statement is not a documented feature. To make this work in a supported way, make USB_ULPI something we ask about if USB_HOST is set. Next, we move the choice of what viewer to use to be after the framework portion and to depend on that. We then borrow a few words from the top-level README to make the help text here clearer. Finally we make the Qualcomm driver select ULPI as it's required and we make the tegra driver not duplicate a check that Kconfig now handles for us. Signed-off-by: Tom Rini

dm: usb: initialize and scan multiple buses simultaneously with uthread

2025-04-23T19:19:44Z

Use the uthread framework to initialize and scan USB buses in parallel for better performance. The console output is slightly modified with a final per-bus report of the number of devices found, common to UTHREAD and !UTHREAD. The USB tests are updated accordingly. Tested on two platforms: 1. arm64 QEMU on a somewhat contrived example (4 USB buses, each with one audio device, one keyboard, one mouse and one tablet) $ make qemu_arm64_defconfig $ make -j$(nproc) CROSS_COMPILE="ccache aarch64-linux-gnu-" $ qemu-system-aarch64 -M virt -nographic -cpu max -bios u-boot.bin \ $(for i in {1..4}; do echo -device qemu-xhci,id=xhci$i \ -device\ usb-{audio,kbd,mouse,tablet},bus=xhci$i.0; \ done) 2. i.MX93 EVK (imx93_11x11_evk_defconfig) with two USB hubs, each with one webcam and one ethernet adapter, resulting in the following device tree: USB device tree: 1 Hub (480 Mb/s, 0mA) | u-boot EHCI Host Controller | +-2 Hub (480 Mb/s, 100mA) | GenesysLogic USB2.1 Hub | +-3 Vendor specific (480 Mb/s, 350mA) | Realtek USB 10/100/1000 LAN 001000001 | +-4 (480 Mb/s, 500mA) HD Pro Webcam C920 8F7CD51F 1 Hub (480 Mb/s, 0mA) | u-boot EHCI Host Controller | +-2 Hub (480 Mb/s, 100mA) | USB 2.0 Hub | +-3 Vendor specific (480 Mb/s, 200mA) | Realtek USB 10/100/1000 LAN 000001 | +-4 (480 Mb/s, 500mA) Generic OnLan-CS30 201801010008 Note that i.MX was tested on top of the downstream repository [1] since USB doesn't work in the upstream master branch.
