<title>hexagon/time: Set -&gt;min_delta_ticks and -&gt;max_delta_ticks</title>

<content type='text'>
In preparation for making the clockevents core NTP correction aware,
all clockevent device drivers must set -&gt;min_delta_ticks and
-&gt;max_delta_ticks rather than -&gt;min_delta_ns and -&gt;max_delta_ns: a
clockevent device's rate is going to change dynamically and thus, the
ratio of ns to ticks ceases to stay invariant.

Make the hexagon arch's clockevent driver initialize these fields
properly.

This patch alone doesn't introduce any change in functionality as the
clockevents core still looks exclusively at the (untouched) -&gt;min_delta_ns
and -&gt;max_delta_ns. As soon as this has changed, a followup patch will
purge the initialization of -&gt;min_delta_ns and -&gt;max_delta_ns from this
driver.

<title>clocksource: Use a plain u64 instead of cycle_t</title>

There is no point in having an extra type for extra confusion. u64 is
unambiguous.

Conversion was done with the following coccinelle script:

-typedef u64 cycle_t;

<title>hexagon/time: Migrate to new 'set-state' interface</title>

<content type='text'>
Migrate hexagon driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

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

We weren't doing anything in the -&gt;set_mode() callback. So, this patch
doesn't provide any set-state callbacks.

 Use resource_size function on resource object
 instead of explicit computation.

 The semantic patch that makes this change is available
 in scripts/coccinelle/api/resource_size.cocci.
