* input: specify the default of I8042_KEYB in more correct mannerMasahiro Yamada2016-10-01-0/+1
| | | | | | | | | | Creating multiple entries of "config FOO" often gives us bad experiences. In this case, we should specify "default X86" as platforms that want this keyboard by default.

* input: Change LED state bits to conform i8042 compatible keyboardBin Meng2015-11-19-3/+3
| | | | | | | | | | | | When sending LED update command to an i8042 compatible keyboard, bit1 is 'Num Lock' and bit2 is 'Caps Lock' in the data byte. But input library defines bit1 as 'Caps Lock' and bit2 as 'Num Lock'. This causes a wrong LED to be set on an i8042 compatible keyboard. Change the LED state bits to be i8042 compatible, and change the keyboard flags as well. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

* input: Allow repeat filtering to be disabledSimon Glass2015-11-19-2/+7
| | | | | | | | | | | | | Generally the input library handles processing of a list of scanned keys. Repeated keys need to be generated based on a timer in this case, since all that is provided is a list of keys current depressed. Keyboards which do their own scanning will resend codes when they want to inject a repeating key. Provide a function which tells the input library to accept repeating keys and not to try to second-guess the caller.

* input: Add a function to add a keycode to the existing setSimon Glass2015-11-19-4/+42
| | | | | | | | | | | | | | | | | | | | | | Most keyboards can be scanned to produce a list of the keycodes which are depressed. With the i8042 keyboard this scanning is done internally and only the processed results are returned. In this case, when a key is pressed, a 'make' code is sent. When the key is released a 'break' code is sent. This means that the driver needs to keep track of which keys are pressed. It also means that any protocol error can lead to stuck keys. In order to support this type of keyboard, add a function when can be used to provide a single keycode and either add it to the list of what is pressed or remove it from the list. Then the normal input_send_keycodes() function can be used to actually do the decoding work. Add debugging to display the ASCII characters written to the input queue also.

| | | | | | | | | | | | | | | | | | CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and CONFIG_CONSOLE_TIME are not used by any board. The implementation is not great and stands in the way of a refactor of i8042. Drop these for now. They can be re-introduced quite easily later, perhaps with driver-model real-time-clock (RTC) support. When reintroducing, it might be useful to make a few changes: - Blink time would be more useful than blink count - The confusing #ifdefs should be avoided - The time functions should support driver model - It would be best keyed off console_tstc() or some similar idle loop rather than a particular input driver (i8042 in this case) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

| | | | | | | | | | | | | | | The existing i8042 keyboard controller driver has some issues. First of all, it does not issue a self-test command (0xaa) to the controller at the very beginning. Without this, the controller does not respond to any command at all. Secondly, it initializes the configuration byte register to turn on the keyboard's interrupt, as U-Boot does not normally allow interrupts to be processed. Finally, at the end of the initialization routine, it wrongly sets the controller to disable all interfaces including both keyboard and mouse.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
