usb: kbd: Do not deregister usbkbd twice when using dm

2016-04-10T15:18:42+00:00

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

usb: kbd: Prevent out of bound access

2016-01-25T21:00:46+00:00

Scan code 0x39 is CapsLock, which is not a printable character and thus
is not covered by either usb_kbd_numkey_shifted[] or usb_kbd_numkey[].
Fix the scan code check to avoid looking it up in either of the arrays.

usb: kbd: don't use int xfers when polling via ctrl xfers

2015-12-17T20:54:41+00:00

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.

Move console definitions into a new console.h file

2015-11-20T03:27:50+00:00

The console includes a global variable and several functions that are only
used by a small subset of U-Boot files. Before adding more functions, move
the definitions into their own header file.

dm: usb: Add support for USB keyboards with driver model

2015-11-20T03:13:39+00:00

Switch USB keyboards over to use driver model instead of scanning with the
horrible usb_get_dev_index() function. This involves creating a new uclass
for keyboards, although so far there is no API.
