Daniel Lezcano 177cf6e52b clocksources: Switch back to the clksrc table
All the clocksource drivers's init function are now converted to return
an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
clksrc-of table.

Let's convert back the names:
 - CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
 - clksrc-of-ret              => clksrc-of

Daniel Lezcano be5eb33d5d clocksource/drivers/asm9260: Convert init function to return error
The init functions do not return any error. They behave as the following:

 - panic, thus leading to a kernel crash while another timer may work and
   make the system boot up correctly

 or

 - print an error and let the caller unaware if the state of the system

Change that by converting the init functions to return an error conforming
to the CLOCKSOURCE_OF_RET prototype.

Proper error handling (rollback, errno value) will be changed later case
by case, thus this change just return back an error or success in the init
function.

Viresh Kumar 3465f60917 clockevents/drivers/asm9260: Migrate to new 'set-state' interface
Migrate asm9260 driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

As a default the timer was stopped when entering in the set_mode(RESUME)
function, now this is done explicitly with the new API.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

Maxime Ripard ff569fcd71 clocksource: asm9260: Fix of_io_request_and_map error check
of_io_request_and map returns an error pointer, but the current code assumes
that on error the returned pointer will be NULL.

Obviously, that makes the check completely useless. Change the test to actually
check for the proper error code.

Oleksij Rempel 8d8bd7be8b ARM: clocksource: Add asm9260_timer driver
In some cases asm9260 looks similar to iMX2x. One of exceptions is
timer controller. So this patch introduces new driver for this special case.
