On Baytrail and Cherrytrail, HDaudio may be fused out or disabled
by the BIOS. This driver enables an alternate path to the i915
display registers and DMA.
Although there is no hardware path between i915 display and LPE/SST
audio clusters, this HDMI capability is referred to in the documentation
as "HDMI LPE Audio" so we keep the name for consistency. There is no
hardware path or control dependencies with the LPE/SST DSP functionality.
The hdmi-lpe-audio driver will be probed when the i915 driver creates
a child platform device.
Since this driver is neither SoC nor PCI, a new x86 folder is added
Additional indirections in the code will be cleaned up in the next series
to aid smoother DP integration

Since recently we have kernel_read_file_from_path(), and it's doing
the same thing as our own home-baked mod_firmware_load(). Let's use
the official API function and clean up the old code.

Define the common hd-audio driver and device types to bind over
snd_hda_bus_type publicly. This allows to implement other type of
device and driver code over hd-audio bus.
Now both struct hda_codec and struct hda_codec_driver inherit these
new struct hdac_device and struct hdac_driver, respectively.
The bus registration is done in subsys_initcall() to assure it
before any other driver registrations.

Add a driver for two playback-only FireWire devices based on the OXFW970
chip.
v2: better AMDTP API abstraction; fix fw_unit leak; small fixes
v3: cache the iPCR value
v4: FireWave constraints; fix fw_device reference counting;
fix PCR caching; small changes and fixes
v5: volume/mute support; fix crashing due to pcm stop races
v6: fix build; one-channel volume for LaCie
v7: use signed values to make volume (range checks) work; fix function
block IDs for volume/mute; always use channel 0 for LaCie volume

Commit 2d4ba4a3b9 introduced a dependency
that was never meant to exist when the ac97_bus.c module was created.
Move ac97_bus.c up the directory hierarchy to make sure it is built when
selected even if sound is configured out so things work as originally
intended.

All sound/sound_firmware.c contains is mod_firmware_load() that is a legacy
API only used by some OSS drivers.
This patch builds it into an own sound_firmware module that is only built
depending on CONFIG_SOUND_PRIME making the kernel slightly smaller for ALSA
users.

When snd-aoa is not built or built as modules, but CONFIG_SND is yes,
kernel build fails due to a bug I introduced when adding snd-aoa. This

This large patch adds all of snd-aoa.
Consisting of many modules, it currently replaces snd-powermac
for all layout-id based machines and handles many more (for
example new powerbooks and powermacs with digital output that
previously couldn't be used at all).
It also has support for all layout-IDs that Apple has (judging
from their Info.plist file) but not all are tested.
The driver currently has 2 known regressions over snd-powermac:
* it doesn't handle powermac 7,2 and 7,3
* it doesn't have a DRC control on snapper-based machines
I will fix those during the 2.6.18 development cycle.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
