The legacy S3C-DMA API required every period of a cyclic buffer to be
queued separately. After conversion of Samsung ASoC to Samsung DMA
wrappers somebody made an assumption that the same is needed for DMA
engine API, which is not true.
In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer
multiple times with a shift of one period per iteration, leading to:
a) severe memory waste - up to 13x times more DMA transfer descriptors
are allocated than needed,
b) possible memory corruption, because further cyclic buffers were out
of the original buffers, due to the offset.
This patch fixes this problem by making the legacy S3C-DMA API use the
same semantics as DMA engine (the whole cyclic buffer is enqueued at
once) and modifying users of Samsung DMA wrappers in cyclic mode to
behave appropriately.

Add support for HDMI audio device on VGA cards that powerdown
to D3cold using non-standard ACPI/PCI infrastructure (optimus).
This does a couple of things to make it work:
a) add a set of power ops for the hdmi domain, and enables them
via vga_switcheroo when we are a switcheroo controlled card. This
just replaces the runtime resume operation so that when the card
is in D3cold the userspace pci config space access via sysfs,
the vga switcheroon runtime resume gets called first and it calls
the GPU resume callback before calling the sound card runtime
resume.
b) standard ACPI/PCI stacks won't put a device into D3cold without
an ACPI handle, but since the hdmi audio devices on gpus don't have
an ACPI handle, we need to manually force the device into D3cold
after suspend from the switcheroo path only.
c) don't try and do runtime s/r when the GPU is off.
d) call runtime suspend/resume during switcheroo suspend/resume
this is to make sure the runtime stack knows to try and resume
the hdmi audio device for pci config space access.
v2: fix incorrect runtime call suspend->resume.
v3: rework irq handler to avoid false irq when we are resuming
but haven't runtime resumed yet, don't bother trying D3cold,
it won't work, just set it manually ourselves, move runtime s/r
calls outside the main s/r hook. enable dnyamic pm properly by
dropping reference.
v4: put back irq handler check just wrap it with cap check

The recent commit to delay the release of kobject triggered NULL
dereferences of opti9xx drivers. The cause is that all
snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers
register the PnP card driver with the very same name, and also
snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with
the same name, too. When these drivers are built in, quick
"register-release-and-re-register" actions occur, and this results in
Oops because of the same name is assigned to the kobject.
The fix is simply to assign individual names. As a bonus, by using
KBUILD_MODNAME, the patch reduces more lines than it adds.
The fix is based on the suggestion by Russell King.

Call snd_soc_dapm_new_widgets() before the auto non-connected pins have been
marked as not connected will power the system under the assumption that those
pins are connected. Once the pins have been marked as disconnected the system
there will be an additional power run. This can cause unnecessary power
transitions. Calling snd_soc_dapm_new_widgets() only after the pins have been
marked as non-connected avoids this.

Each time snd_soc_dapm_new_widgets() is called it will instantiate all the

result in extra register writes and and also might cause clicks and pops.

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. So, fix the drivers and documentation, too.
