2020-09-01usb: gadget: Fix controller index in UMSYe Li1-2/+4
The usb mass storage (f_mass_storage.c) uses fixed usb index 0, this causes problem while CDNS3 USB controller index is 1. Modify the API of fsg to pass the controller index. Reviewed-by: Jun Li <jun.li@nxp.com> Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2020-02-05dm: core: Require users of devres to include the headerSimon Glass1-0/+1
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2018-12-14usb: composite: Move bitmap related operations to ./include/linux/bitmap.hLukasz Majewski1-1/+1
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 <lukma@denx.de> Reviewed-by: Stefan Agner <stefan.agner@toradex.com>

Often during debugging session it's very interesting to see what data we were dealing with. For example what we write or read to/from memory or peripherals.

2018-05-15usb: f_mass_storage: Fix set_bit and clear_bit usageBryan O'Donoghue1-22/+3
Compiling the f_mass_storage driver for an x86 target results in a compilation error as set_bit and clear_bit are provided by bitops.h Looking at the provenance of the current u-boot code and the git change history in the kernel, it looks like we have a local copy of set_bit and clear_bit as a hold-over from porting the Linux driver into u-boot. These days __set_bit and __clear_bit are optionally provided by an arch and can be used as inputs to generic_bit_set and generic_bit_clear. This patch switches over to generic_set_bit and generic_clear_bit to accommodate.

2018-05-07SPDX: Convert all of our multiple license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>

2016-01-13ums: support multiple LUNs at onceStephen Warren1-10/+12
Extend the ums command to accept a list of block devices. Each of these will be exported as a separate LUN. An example use-case would be: ums 0 mmc 0,0.1,0.2 ... which would export LUNs for eMMC 0's user data, boot0, and boot1 HW partitions. This is useful since it allows the host access to everything on the eMMC without having to somehow stop the ums command from executing and restart it with different parameters.

2015-04-14usb: modify usb_gadget_handle_interrupts to take controller indexKishon Vijay Abraham I1-1/+1
Since we support multiple dwc3 controllers to be existent at the same time, in order to handle the interrupts of a particular dwc3 controller usb_gadget_handle_interrutps should take controller index as an argument. Hence the API of usb_gadget_handle_interrupts is modified to take controller index as an argument and made the corresponding changes to all the usb_gadget_handle_interrupts calls.

2014-05-05usb: dfu: fix boards wo USB cable detectionMateusz Zalega1-4/+4
Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.
