* usb: Drop usb_disable_asynch()Andrey Smirnov2019-03-111-1/+0
| | | | | | | | | | There are no users of usb_control_msg() in the codebase that pass timeout of 0, so it doesn't look like usb_disable_asynch() has any effect on USB operation. Drop that function and remove all of its uses to simplify things. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb: gadget: fastboot: pass message type as enumSascha Hauer2018-12-071-1/+9
| | | | | | | | We used to pass the message type ("INFO", "FAIL", "OKAY") as strings to fastboot_tx_print(). Change this to a enum type. This allows fastboot_tx_print() to react on the message type in the next step. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usbgadget: autostart: add DFU supportLadislav Michl2018-10-291-0/+4
| | | | | | | | | | | Use global variable dfu_function to autostart DFU. As similar code is used to start multifunction gadget using command, move common code to common/usbgadget.c and consolidate it. It turned out that '-s' option of usbgadget command does nothing, so remove its help text and make it function as '-a'.

* usb: gadget: fsl_udc: pass controller instance to unregisterSascha Hauer2018-10-291-2/+4
| | | | | | | | | | | | | ci_udc_unregister() used to unregister "the controller". Since we may register multiple chipidea devices we called ci_udc_unregister() for each of them. This led to messages like: ERROR: imx-usb 53f80000.usb: gadget not registered. Fix this by returning the registered controller. This allows us to call ci_udc_unregister() only when we actually registered one before. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: host: ehci: do not use dev->privSascha Hauer2018-10-291-0/+6
| | | | | | | | | | | | | | An ehci can be registered with ehci_register which is passed a struct device_d *. In that case the priv pointer may already be used by the caller, so we must not use it in the ehci code. At least for the Atmel ehci driver this fixes a bug, here dev->priv is set two times to different values. Since we need dev->priv in the ehci code to get the controller in ehci_detect() we can no longer implement that without the help of the caller, hence we eport ehci_detect() and epect it to be called by the code which registers a ehci host.

* usb: host: ehci: add ehci_unregister()Sascha Hauer2018-10-291-3/+11
| | | | | | | | | ehci_register() allocates data and registers a ehci host. Add ehci_unregister() to properly halt the controller and to free the memory again.. To do so, change ehci_register() to return the ehci host rather than an error code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: Add usb_unregister_host()Sascha Hauer2018-10-261-0/+1
| | | | | | | | We have usb_register_host() which puts a new host on the list of hosts we should also have the opposite which removes the host from the list again. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: imx: implement support for limiting host to full speedNikita Yushchenko2018-06-263-0/+10
| | | | | | | | | | | | | | | | | | This is needed when host is known to not work properly in high speed mode. In linux, chipidea driver supports 'maximum-speed' device tree property. When that is set to "full-speed", driver sets PFSC bit in PORTSC register, which disallows use of high speed mode. This patch implements same support for barebox. Important technical detail is that PFSC bit is cleared by port reset, thus setting it has to be done in ehci->init() callback which is called after ehci_reset().

* usb: gadget: fastboot: Add external command execution supportSascha Hauer2018-02-091-0/+17
| | | | | | | | | | | | | | | | Custom projects may need vendor specific expansions to the fastboot command execution. Allow these to be implemented without messing in the fastboot code directly. We have a hook for all commands and also one for the "flash" command. Each hook can decide if the generic command parser is executed afterwards (return value FASTBOOT_CMD_FALLTHROUGH) or if the generic parser shall be skipped (return value 0 or negative error code). This allows board code to implement vendor specific "oem" commands or to handle the downloaded image in a special way (i.e. do signature checks on them) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usbgadget: fastboot: Allow to automatically export the bbu handlersSascha Hauer2017-09-271-0/+7
| | | | | | | | | | We have a list of registered handlers which take a barebox update. Do the next step and allow to automatically export them via fastboot so that barebox can be updated via fastboot without manually exporting the partition. Since this may not be desirable in all cases this behaviour is configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* usb: gadget: properly release f_multi_optsSascha Hauer2017-03-091-0/+2
| | | | | | | | | | | | | | | | The usbgadget commands uses statically allocated f_multi_opts and passes this to usb_multi_register(). These f_multi_opts are of course no longer valid when we leave the usbgadget command. Luckily we do not use the data after we left the usbgadget command, so this never has been a problem. However, f_multi_opts has some allocated members which we can not free anymore on gadget unregistration because we no longer have the pointer to them. Fix this by adding a release function to struct f_multi_opts. This way we can allocate all memory dynamically and properly free it when not used anymore.

| | | | | | | | | | | | | | | | | | | | | | | | The host may assume that the usb device is still up and running after booting if we do not deregister the udc here.

* usb: increase USB_CNTL_TIMEOUT to match linuxSteffen Trumtrar2015-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | USB requests should be processed within a timeframe of 5s. The linux kernel also uses this timeout value for the control packets. For the musb the increase in timeout helps successfully probing USB devices (at least on one test hardware), but on the other hand doesn't slow down the system, if there are no devices, i.e. the timeout never hits. That means, that the USB core correctly aborts instead of timing out. Why and how the 100ms was chosen in the first place, can not be deduced from the git history, just that it seems to work fine for most boards. Change USB_CNTL_TIMEOUT to 5000ms and replace all occurences of `USB_CNTL_TIMEOUT * x` with just `USB_CNTL_TIMEOUT`, as the timeout is now large enough without it.
