usb: dwc3-generic: Disable host driver definition if gadget only

2021-05-16T17:01:45Z

Even if only USB gadget is defined, dwc3 generic driver enables a definition and probe/remove functions for host driver. This enables the definition if USB_HOST is enabled only. Signed-off-by: Kunihiko Hayashi

usb: musb-new: Extend and move Allwinner quirk into Kconfig

2021-05-16T17:01:45Z

All newer Allwinner SoCs (since about 2013) miss the CONFIGDATA register in their MUSB implementation, so they need a quirk to hardcode this. Currently this quirk depends on listing the SoCs affected in musb_reg.h, which means that this list needs to grow with every new chip. Move the quirk feature into Kconfig, next to PIO_ONLY, and change the default to y (for Allwinner builds), while listing the early implementations as exceptions. This fixes USB peripheral operation on some newer SoCs, which were not explicitly listed before. Tested on H6, H616, R40 (which were broken before), and also on the H5 and A20, for regressions.

usb: dwc3-meson-g12a: skip phy on -ENODATA aswell

2021-05-14T15:41:12Z

If the PHY isn't specified in the DT, -ENODATA means it should be skipped, handle it like -ENOENT. With that, devices without USB3 supported can have USB working (Odroid-HC4). Fixes: adb049abf7 ("usb: dwc3: Add Meson G12A USB Glue") Signed-off-by: Neil Armstrong

usb: ehci-mx6: Limit PHY address parsing to !CONFIG_PHY

2021-04-28T15:16:18Z

For systems which use generic PHY support and implement USB PHY driver, the parsing of PHY properties is unnecessary, disable it. Signed-off-by: Marek Vasut Tested-by: Ying-Chun Liu (PaulLiu) Cc: Fabio Estevam Cc: Peng Fan Cc: Stefano Babic Cc: Ye Li Cc: uboot-imx

usb: ehci-hcd: Add IAA handshake for removing async QH

2021-04-22T19:09:57Z

According to EHCI spec, software needs to do handshake with HC for safely removing QH from async list. This handshake is implemented by setting IAAD (Interrupt on Async Advance Doorbell) bit in USB_USBCMD register and poll the IAA (Interrupt on Async Advance bit) in the USB_USBSTS to ensure the HC has released all on-chip state that may potentially reference one of the data structures just removed. Current codes only check active status of the last QTD, but this can't ensure the QH is released from HC. We can meet unrecoverable "EHCI timed out on TD" errors when running UEFI SCT tests on USB disk. The USB_ASYNCLISTADDR register is changed to a invalid address when the issue happens. It is fixed after adding the IAA handshake. Steps to reproduce the issue: 1. Build the UEFI SCT from https://github.com/tianocore/edk2-test 2. Build the EDK2 UEFI Shell from https://github.com/tianocore/edk2 3. Copy SCT files and Shell.efi to USB disk FAT partition 4. Load the Shell.efi from USB FAT, and run bootefi to execute it 5. After booting into Shell, enter the SCT directory and run "sct -a" to execute all tests. 6. Tests run about 1 hour and stop with many EHCI timeout errors like EHCI timed out on TD - token=0x801f8c80 Signed-off-by: Ye Li

usb: ehci-mx6: Add iMX8M support

2021-04-18T02:29:36Z

The iMX8M uses nop PHY, select PHY and NOP_PHY automatically. Otherwise, the DM capable driver is now perfectly compatible. Signed-off-by: Marek Vasut Cc: Fabio Estevam Cc: Peng Fan Cc: Stefano Babic Cc: Ye Li Cc: uboot-imx

usb: ehci-mx6: Fix aarch64 build warnings

2021-04-18T02:29:36Z

Fix cast from pointer to integer of different size by casting the pointer to uintptr_t instead of uint32_t, the former has correct size on both 32bit and 64bit architectures. Signed-off-by: Marek Vasut Cc: Fabio Estevam Cc: Peng Fan Cc: Stefano Babic Cc: Ye Li Cc: uboot-imx

usb: ehci-mx6: Set default CONFIG_MXC_USB_PORTSC if not defined

2021-04-18T02:29:36Z

There is now multiple copies of CONFIG_MXC_USB_PORTSC in configs set to PORT_PTS_UTMI | PORT_PTS_PTW, which is in fact the default register value for MX6, MX7 and MX7ULP. Define the default value of CONFIG_MXC_USB_PORTSC in the driver and use it in case CONFIG_MXC_USB_PORTSC is not defined in config, to reduce the duplication.
