usb: dwc2: handle return code of dev_read_size() in of to, plat function

2022-03-14T11:31:12Z

dev_read_size() returns -EINVAL (-22) if the property "g-tx-fifo-size" does not exist. If that's the case, we now keep the default value of 0. Signed-off-by: Wolfgang Grandegger

The ci_req->hw_buf can be NULL, test whether it is and if so, avoid accessing it. Else, the system may crash. Signed-off-by: Marek Vasut Cc: Peter Chen Cc: Li Jun Cc: Peng Fan

dfu: handle short frame result of UPLOAD in state_dfu_idle

2022-01-28T15:21:51Z

In DFU v1.1 specification [1] the DFU_UPLOAD (Short Frame) is handled only in dfuUPLOADIDLE state: - Figure A.1 Interface state transition diagram - the state description in chapter A.2 A.2.3 State 2 dfuIDLE on Receipt of the DFU_UPLOAD request,and bitCanUpload = 1 the Next State is dfuUPLOADIDLE A.2.10 State 9 dfuUPLOAD-IDLE When the length of the data transferred by the device in response to a DFU_UPLOAD request is less than wLength. (Short frame) the Next State is dfuIDLE In current code, when an UPLOAD is completely performed after the first request (for example with wLength=200 and data read = 9), the DFU state stay at dfuUPLOADIDLE until receiving a DFU_UPLOAD or a DFU_ABORT request even it is unnecessary as the previous DFU_UPLOAD request already reached the EOF. This patch proposes to finish the DFU uploading (don't go to dfuUPLOADIDLE) and completes the control-read operation (go to DFU_STATE_dfuIDLE) when the first UPLOAD response has a short frame as an end of file (EOF) indicator even if it is not explicitly allowed in the DFU specification but this seems logical.

usb: gadget: Add CDC ACM function

2022-01-26T22:23:17Z

Add support for CDC ACM using the new UDC and gadget API. This protocol can be used for serial over USB data transfer and is widely supported by various OS (GNU/Linux, MS-Windows, OSX...). The usual purpose of such link is to access device debug console and can be useful for products not exposing regular UART to the user. A default stdio device named 'usbacm' is created, and can be used to redirect console to USB link over CDC ACM: > setenv stdin usbacm; setenv stdout usbacm Signed-off-by: Loic Poulain

SPL: Add struct spl_boot_device parameter into spl_parse_board_header()

Fastboot support has been broken on platforms using dwc2 controller since the gadget gets its max packet size from it. This patch is the equivalent of 723fd5668ff which fixed the same issue but for the chipidea controller.
