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

2019-01-10T17:52:55Z

The SPL option for USB gadget should be named after the option for u-boot (CONFIG_USB_GADGET) Signed-off-by: Jean-Jacques Hiblot

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.

dm: usb: create a new UCLASS ID for USB gadget devices

2018-12-07T15:31:45Z

UCLASS_USB_DEV_GENERIC was meant for USB devices connected to host controllers, not gadget devices. Adding a new UCLASS for gadget devices alone. Also move the generic DM code for USB gadgets in a separate file for clarity. Signed-off-by: Jean-Jacques Hiblot

usb: udc: implement DM versions of usb_gadget_initialize()/_release()/_handle_interrupt()

2018-12-07T15:31:45Z

When DM_USB_GADGET the platform code for the USB device must be replaced by calls to a USB device driver. usb_gadget_initialize() probes the USB device driver. usb_gadget_release() removes the USB device driver. Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Lukasz Majewski

usb: gadget: Do not call board_usb_xxx() directly in USB gadget drivers

2018-12-07T15:31:45Z

Add 2 functions to wrap the calls to board_usb_init() and board_usb_cleanup(). This is a preparatory work for DM support for UDC drivers (DM_USB_GADGET). Signed-off-by: Jean-Jacques Hiblot Reviewed-by: Lukasz Majewski

usb: s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/

This allows to disable the USB driver model in SPL because it checks the CONFIG_SPL_DM_USB variable for SPL builds. Nothing changes for regular non-SPL builds. Signed-off-by: Sven Schwermer
