Ramakrishna Pallala e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

Patrik Flykt 4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

Andy Ross 3630641bcc include/drivers: Fix docs on z_clock_set_timeout()
This wasn't explained correctly.  The tick convention we use here
(owing to the way legacy code was written) is a little weird.  Timeout
delays are passed in a "round down" sense, so that setting a timeout
in "one tick" means that the interrupt will arrive anywhere between
zero and one ticks in the future.

Andy Ross 96013b0375 system_timer.h: Change "now" uptime API to be simpler for drivers
The current z_clock_uptime() call (recently renamed from
_get_elapsed_program_time) requires the driver to track a full 64 bit
uptime value in ticks, which is entirely separate from the one the
kernel is already keeping.

Don't do that.  Just ask the drivers to track uptime since the last
call to z_clock_announce(), since that is going to map better to
built-in hardware capability.

Obviously existing drivers already have this feature, so they're
actually getting slightly larger in order to implement the new API in
terms of the old one.  But future drivers will thank us.

Andy Ross 722a888ef7 timer: Clean up hairy tickless APIs
The tickless driver had a bunch of "hairy" APIs which forced the timer
drivers to do needless low-level accounting for the benefit of the
kernel, all of which then proceeded to implement them via cut and
paste.  Specifically the "program_time" calls forced the driver to
expose to the kernel exactly when the next interrupt was due and how
much time had elapsed, in a parallel API to the existing "what time is
it" and "announce a tick" interrupts that carry the same information.

Remove these from the kernel, replacing them with synthesized logic
written in terms of the simpler APIs.

In some cases there will be a performance impact due to the use of the
64 bit uptime call, but that will go away soon.

Andy Ross ab488277bc drivers/timer: Unify timeout setting APIs
The existing API had two almost identical functions: _set_time() and
_timer_idle_enter().  Both simply instruct the timer driver to set the
next timer interrupt expiration appropriately so that the call to
z_clock_announce() will be made at the requested number of ticks.  On
most/all hardware, these should be implementable identically.

Unfortunately because they are specified differently, existing drivers
have implemented them in parallel.

Specify a new, unified, z_clock_set_timeout().  Document it clearly
for implementors.  And provide a shim layer for legacy drivers that
will continue to use the old functions.

Note that this patch fixes an existing bug found by inspection: the
old call to _set_time() out of z_clock_announce() failed to test for
the "wait forever" case in the situation where clock_always_on is
true, meaning that a system that reached this point and then never set
another timeout would freeze its uptime clock incorrectly.

Andy Ross fa99ad66d0 sys_clock: Fix up tick announce API
There were three separate "announce ticks" entry points exposed for
use by drivers.  Unify them to just a single z_clock_announce()
function, making the "final" tick announcement the business of the
driver only, not the kernel.

Note the oddness with "_sys_idle_elapsed_ticks": this was a global
variable exposed by the kernel.  But it was never actually used by the
kernel.  It was updated and inspected only within the timer drivers,
and only so that it could be passed back to the kernel as the default
(actually hidden) argument to the announce function.  Break this false
dependency by putting this variable into each timer driver
individually.
