usb: udc-uclass: Fixed problem when no alias is defined in DT

2019-03-16T12:29:43Z

commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports" changed the way the udevice if found. It uses the alias to find a udevice for a given USB port number. In the commit log it was stated that if no alias is provided, the bind order will be used instead. However it doesn't work. Fixing this by adding a call to uclass_get_device() if uclass_get_device_by_seq() fails. Signed-off-by: Jean-Jacques Hiblot Tested-by: Vignesh R

usb: ether: call _usb_eth_halt() if initialization fails

2019-02-01T14:09:40Z

If the host does not respond in time, the initialization fails. However the usb ether driver will still be registered. This will make usb_gadget_probe_driver() fail the next time the initialization is attempted because it cannot find an available UDC. Fixing this by calling _usb_eth_halt() when the init fails.

spl: Kconfig: Drop the _SUPPORT postfix from SPL_DFU

2019-01-26T13:13:54Z

The symbol CONFIG_SPL_DFU_SUPPORT in SPL build has the same meaning as CONFIG_DFU in regular U-Boot. Drop the _SUPPORT to allow for cleaner use in code. Signed-off-by: Andrew F. Davis Reviewed-by: Tom Rini Acked-by: Lukasz Majewski

net: remove CONFIG_MCAST_TFTP

2019-01-24T17:35:30Z

No mainline board enables CONFIG_MCAST_TFTP and there have been compilation issues with the code for some time. Additionally, it has a potential buffer underrun issue (reported as a side note in CVE-2018-18439). Remove the multicast TFTP code but keep the driver API for the future addition of IPv6.

dm: usb: gadget: Fix boot breakage on sunxi platforms

2019-01-10T17:53:03Z

Fixes commit 013116243950 ("dm: usb: create a new UCLASS ID for USB gadget devices") The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared even for platforms that do not enable DM_USB_GADGET. Otherwise the driver for their usb peripheral controller fails to bind. Reported-by: Priit Laes Reported-by: Jagan Teki Signed-off-by: Jean-Jacques Hiblot Tested-by: Priit Laes Acked-by: Jagan Teki

Kconfig: rename CONFIG_SPL_USB_GADGET_SUPPORT as CONFIG_SPL_USB_GADGET

dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports

2019-01-10T17:52:51Z

dfu, fastbot and other usb gadget commands take the USB port index as a parameter. Currently this index is assigned in the order of the driver bindings. Changing this behavior using the SEQ_ALIAS feature. This option assign to the device a SEQ number based on its alias (if it exists) To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing naming convention: use "usb" for the name of the gadget UCLASS_DRIVER (same as for the UCLASS_USB). If no alias is provided, then the index falls back to the order in which the bindings took place.

usb: composite: Fix max packet size for USB3.0

2018-12-14T16:59:10Z

For USB3.0, the max packetsize for GET_DESCRIPTOR should be sent as exponent value for 2. This means for 512, max packet size should be filled with 9(2^9=512). Also, fill the USB version field with 3.0 if speed is negotiated to Superspeed. This fixes the issue of DFU gadget download failure with superspeed. Without this patch, the max packet size is overflowed to zero as the bMaxPacketsize is of u8 and hence host is not able to detect this device.

usb: composite: Move bitmap related operations to ./include/linux/bitmap.h

2018-12-14T16:59:08Z

The BITMAP related operations can now be moved to ./include/linux/bitmap.h file to mimic the Linux kernel directory tree. This change also allows to remove the lin_gadget_compat.h header file (which is a legacy code only for composite U-boot layer). It was also possible to remove #includes from several USB gadget drivers. Signed-off-by: Lukasz Majewski Reviewed-by: Stefan Agner

usb: gadget: f_sdp: Provide filesize env variable for downloaded images

2018-12-14T16:59:08Z

Currently it's not possible to get filesize of downloaded images and it's impossible to automate some tasks in scripts. So this patch adds `filesize` environment variable with size (as hex number in bytes) of the last successfully downloaded file via `sdp` command.
