      serial: sh-sci: clkdev updates for MSTP gating. · c7ed1ab3
      Paul Mundt authored 
      This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.

As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.

      sh: Kill off all timer name clobbering. · ec0ffe2e
      Paul Mundt authored 
      Now that dev_name() can be used early, we no longer require a static
string. Kill off all of the superfluous timer names.

      clocksource: Use dev_name() universally across the SH drivers. · 214a607a
      Paul Mundt authored 
      There is no need to copy in the name from the sh timer config now that
dev_name() is available early. We prefer the dev_name() variant for
consistent naming.

      driver core: Early dev_name() support. · a636ee7f
      Paul Mundt authored 
      Presently early platform devices suffer from the fact they are unable to
use dev_xxx() calls early on due to dev_name() and others being
unavailable at the time ->probe() is called.

This implements early init_name construction from the matched name/id
pair following the semantics of the late device/driver match. As a
result, matched IDs (inclusive of requested ones) are preserved when the
handoff from the early platform code happens at kobject initialization
time.

Since we still require kmalloc slabs to be available at this point, using
kstrdup() for establishing the init_name works fine. This subsequently
needs to be tested from dev_name() prior to the init_name being cleared
by the driver core. We don't kfree() since others will already have a
handle on the string long before the kobject initialization takes place.

This is also needed to permit drivers to use the clock framework early,
without having to manually construct their own device IDs from the match
id/name pair locally (needed by the early console and timer code on sh
and arm).
