Similar like the case for Realtek, VIA codec driver needs this ops as
well for making the widget power-save working.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

While enabling the widget power-saving for ALC269 & co, the important
setup was forgotten -- stream_pm ops.  Without this setup, the paths
for PCM won't be powered up at all.

Also, the power_filter callbacks used in ALC269 & co need to chain to
the default snd_hda_gen_path_power_filter().

Currently the generic parser sets codec->power_filter when
power_save_node flag is set.  But this overrides the existing filter
that has been already set by the codec driver, thus it looses some
features.  Instead, set the default power_filter only when it's not
set yet.

Add the check of power_save_node flag at the beginning of the function
so that it skips the rest if the flag isn't set.  In this way, we can
call this function safely no matter whether the widget power-saving is
really used or not.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

When the widget power-saving is enabled, the first automute hook
invocation checks through the whole pins and it also tries to
synchronize the power state.  However, this results in a wrong state
because it calls unconditionally snd_hda_jack_detect_state().
This patch adds a check of jack detectability before the actual jack
detection call.

The new widget power-saving tries to apply the power change no matter
whether the node has a power cap or not.  It's bad (although most of
codecs chip just ignore it).  Check the capability properly
beforehand.

The hdac regmap code checks whether the codec is powered on while
accessing, but there must be an exception -- the verbs to control the
power state.

Currently HD-audio driver doesn't access them via regmap, so this
patch doesn't fix any current behavior, but it's just for future.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

Currently, snd_hdac_power_up()/down() helpers checks whether the codec
is being in pm (suspend/resume), and skips the call of runtime get/put
during it.  This is needed as there are lots of power up/down
sequences called in the paths that are also used in the PM itself.  An
example is found in hda_codec.c::codec_exec_verb(), where this can
power up the codec while it may be called again in its power up
sequence, too.

The above works in most cases, but sometimes we really want to wait
for the real power up.  For example, the control element get/put may
want explicit power up so that the value change is assured to reach to
the hardware.   Using the current snd_hdac_power_up(), however,
results in a race, e.g. when it's called during the runtime suspend is
being performed.  In the worst case, as found in patch_ca0132.c, it
can even lead to the deadlock because the code assumes the power up
while it was skipped due to the check above.

For dealing with such cases, this patch makes snd_hdac_power_up() and
_down() to two variants: with and without in_pm flag check.  The
version with pm flag check is named as snd_hdac_power_up_pm() while
the version without pm flag check is still kept as
snd_hdac_power_up().  (Just because the usage of the former is fewer.)

Then finally, the patch replaces each call potentially done in PM with
the new _pm() variant.

In theory, we can implement a unified version -- if we can distinguish
the current context whether it's in the pm path.  But such an
implementation is cumbersome, so leave the code like this a bit messy
way for now...

   - Lines-wise, largest is a PXA fix for dealing with interrupts on DT
     that was quite broken.  It's still newish code so while we could
     have held this off, it seemed appropriate to include now

   - Some GPIO fixes for OMAP platforms added a few lines.  This was
     also fixes for code recently added (this release).

   - Small OMAP timer fix to behave better with partially upstreamed
     platforms, which is quite welcome.

   - Allwinner fixes about operating point control, reducing
     overclocking in some cases for better stability.
