usb: Tidy up the usb_start flag

2023-05-13T13:52:32Z

This should be declared in a header file so that type-checking works correctly. Add a single declaration to usb.h and remove the others. Signed-off-by: Simon Glass Reviewed-by: Marek Vasut Reviewed-by: Patrick Delaunay

usb: Add 1ms delay after first Get Descriptor request

2022-11-03T22:36:48Z

Logitech Unifying Receiver 046d:c52b bcdDevice 12.10 seems sensitive about the first Get Descriptor request. If there are any other requests in the same microframe, the device reports bogus data, first of the descriptor parts is not sent to the host. Wait over one microframe duration before issuing subsequent requests to avoid probe failure with this device, since it can be used to connect USB keyboards.

usb: Keep async schedule running only across mass storage xfers

2020-04-09T19:26:59Z

Rather than keeping the asynchronous schedule running always, keep it running only across USB mass storage transfers for now, as it seems that keeping it running all the time interferes with certain control transfers during device enumeration. Note that running the async schedule all the time should not be an issue, especially on EHCI HCD, as that one implements most of the transfers using async schedule. Note that we have usb_disable_asynch(), which however is utterly broken. The usb_disable_asynch() blocks the USB core from doing async transfers by setting a global flag. The async schedule should however be disabled per USB controller. Moreover, setting a global flag does not prevent the controller from using the async schedule, which e.g. the EHCI HCD does. This patch implements additional callback to the controller, which permits it to lock the async schedule and keep it running across multiple transfers. Once the schedule is unlocked, it must also be disabled. This thus prevents the async schedule from running outside of the USB mass storage transfers.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

usb: s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/

2018-11-26T20:19:03Z

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
