2ad1660ae4 gpiokeys: add evdev support
Only linux,code is supported as it maps 1:1 to evdev key codes.
No reverse mapping for freebsd,code yet.

2899979df9 Revert r355806: kbd drivers: don't double register keyboard drivers
r356087 made it rather innocuous to double-register built-in keyboard
drivers; we now set a flag to indicate that it's been registered and only
act once on a registration anyways. There is no misleading here, as the
follow-up kbd_delete_driver will actually remove the driver as needed now
that the linker set isn't also consulted after kbdinit.

5a7a578be9 kbd drivers: don't double register keyboard drivers
Keyboard drivers are generally registered via linker set. In these cases,
they're also available as kmods which use KPI for registering/unregistering
keyboard drivers outside of the linker set.

For built-in modules, we still fire off MOD_LOAD and maybe even MOD_UNLOAD
if an error occurs, leading to registration via linker set and at MOD_LOAD
time.

This is a minor optimization at best, but it keeps the internal kbd driver
tidy as a future change will merge the linker set driver list into its
internal keyboard_drivers list via SYSINIT and simplify driver lookup by
removing the need to consult the linker set.

eefc662f0b kbd: provide default implementations of get_fkeystr/diag
Most keyboard drivers are using the genkbd implementations as it is;
formally use them for any that aren't set and make
genkbd_get_fkeystr/genkbd_diag private.

4434de9643 kbd drivers: use kbdd_* indirection for diag invocation
These invocations were directly calling enkbd_diag(), rather than
indirection back through kbdd_diag/kbdsw. While they're functionally
equivent, invoking kbdd_diag where feasible (i.e. not in a diag
implementation) makes it easier to visually identify locking needs in these
other drivers.

80d6dbeea0 Remove more needless <sys/tty.h> includes
As part of my journey to make it easy to determine what's relying on tty
bits, remove a couple more. Some of these just outright didn't need it,
while others did rely on <sys/tty.h> pollution for mutex headers.

217d17bcd3 Clean up OF_getprop_alloc API
OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.

For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

- Unregister keyboard when detaching device node

bc90a48ccf Add OF_prop_free function as a counterpart for OF_*prop_alloc
- Introduce new OF API function OF_prop_free to free memory allocated by
  OF_getprop_alloc and OF_getencprop_alloc. Current code just calls free(9)
  with M_OFWPROP memory class which assumes knowledge about OF_*prop_alloc
  functions' internals and leads to unneccessary code coupling

- Convert some of the free(..., M_OFWPROP) instances to OF_prop_free

Files affected by this commit are the ones I was able to test on real
hardware. The rest of free(..., M_OFWPROP) instances will be handled with
idividual maintainers

5a333f6f5f Add gpiokeys driver
gpiokey driver implements functional subset of gpiokeys device-tree bindings:
https://www.kernel.org/doc/Documentation/devicetree/bindings/input/gpio-keys.txt

It acts as a virtual keyboard, so keys are visible through kbdmux(4)

Driver maps linux scancodes for most common keys to FreeBSD scancodes and
also extends spec by introducing freebsd,code property to specify
FreeBSD-native scancodes.
