* usb: kbd: Do not deregister usbkbd twice when using dmHans de Goede2016-04-10-1/+2
| | | | | | | | | | | | | | The dm usb_kbd_remove function() will deregister the usb keyboard for us on a "usb reset" / "usb stop" so there is no need to manually call usb_kbd_deregister() in the dm case. This commit removes usb_kbd_deregister() in the dm case fixing the following "usb reset" errors: usb_kbd_remove: warning, ret=-6 device_remove: Device 'usb_kbd' failed to remove, but children are gone Signed-off-by: Hans de Goede <hdegoede@redhat.com>

* usb: kbd: don't use int xfers when polling via ctrl xfersStephen Warren2015-12-17-0/+3
| | | | | | | | | | | | When CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP is enabled, use a GET_REPORT control transfer to retrieve the initial state of the keyboard. This matches the technique used to poll the keyboard state. This is useful since it eliminates the remaining use of interrupt transfers from the USB keyboard driver, which allows it to work with USB HCD that don't support interrupt transfers.

* usb: kbd: Disable idle input reports when we do not need themHans de Goede2015-06-19-1/+3
| | | | | | | | When we're polling and thus handling key-repeat in software, make sure to disable idle reports, some keyboards may have these enabled by default messing up our software keyrepeat. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* usb: kbd: Fix key repeat not always workingHans de Goede2015-05-29-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | The usb-kbd key repeat code assumes that reports get repeated every 40 ms, this is never true when using CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP, and does not always works for CONFIG_SYS_USB_EVENT_POLL and CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE since not all usb keyboards honor the usb_set_idle() command. For CONFIG_SYS_USB_EVENT_POLL we must use usb_set_idle() since we do a blocking wait for the hid report, so if we do not tell the keyboard to send a hid report every 40ms even if nothing changes then we will block u-boot for 1s (the default u-boot usb interrupt packet timeout). Note that in this case on keyboards which do not support usb_set_idle() we loose and we actually get 1s latencies on other u-boot activities. For the other poll-methods this commit stops using usb_set_idle() and instead repeats the last received hid-report every 40 ms as long as no new hid-report is received. This fixes key-repeat not working at all with CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP and fixes it not working with keyboards which do not implement usb_set_idle() when using CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE.

* usb: Fix usb_kbd_deregister when console-muxing is usedHans de Goede2015-01-18-0/+4
| | | | | | | | | | | | | When iomuxing is used we must not only deregister the device with stdio.c, but also remove the reference to the device in the console_devices array used by console-muxing. Add a call to iomux_doenv to usb_kbd_deregister to update console_devices, which will drop the reference. This fixes the console filling with "Failed to enqueue URB to controller" messages after a "usb stop force", or when the USB keyboard is gone after a "usb reset".

* usb: Add an interval parameter to create_int_queueHans de Goede2015-01-18-2/+4
| | | | | | | | Currently create_int_queue is only implemented by the ehci code, and that does not honor interrupt intervals, but other drivers which might also want to implement create_int_queue may honor intervals, so add an interval param. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* usb: kbd: Add (optional) support for using an interrupt queue for pollingHans de Goede2014-11-04-0/+19
| | | | | | | | | | | | | | | Waiting an interrupt packet to complete in usb_kbd_poll_for_event, causes a 40 ms latency for each call to usb_kbd_testc, which is undesirable. Using control messages leads to lower (but still not 0) latency, but some devices do not work well with control messages (e.g. my kvm behaves funny with them). This commit adds support for using the int_queue mechanism which at least the ehci-hcd driver supports. This allows polling with 0 latency, while using interrupt packets.

* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away.

The dublicates in usb.h are removed. The extra element structure will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface For these, the common descriptor elements are accessed now by an element 'desc'.
