Migrate TEGRA_KEYBOARD from headers to Kconfig, only the seaboard uses it but we
drop CONFIG_KEYBOARD as the driver doesn't use the legacy drv_keyboard_init.

We should not have exported functions in a driver. The i8042_disable()
function is used to disable the keyboard. Provide a remove() method
instead, which is the standard way of disabling a device.
We could potentially add a method to flush input but that does not seem
necessary.

This converts the following to Kconfig:

This also removes dead references to:

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

Update this driver and key_matrix to support a live device tree.
Signed-off-by: Simon Glass <[email protected]>

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to

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.

At present the i8042 driver has its own logic and keymaps. In an effort to
unify the code, move it over to use the input library. This changes most of
the keycode-processing logic since it is now in that library. The main
responsibilities of the driver are now to handle the LEDs, deal with the
PS/2 extended keycodes and initialise the the keyboard.

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.

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)
