MacBook Pro 10,1 needs a few adjustments to make it working:
- more COEF verbs
- some pin config overrides to disable the unused pin (0x0d, 0x12),
and fix the internal mic (0x0e)
In addition, it uses GPIO 1 and 3 like other MacBooks.
The internal digital mic on the machine is still problematic: it seems
that only the right channel is used and the left is always static.
This looks like a hardware design, so we need to cope in the software
side somehow...

snd_hda_codec_reset() calls restore_pincfgs() where the codec is

free callback, thus no codec callbacks should be called after that.

Recently the check for non-PCM stream state was added to the generic

The recent fix for the missing fine delayed time adjustment gives
strange error messages at each start of the playback stream, such as
delay: estimated 0, actual 352
delay: estimated 353, actual 705
These come from the sanity check in retire_playback_urb(). Before the
stream is activated via start_endpoints(), a few silent packets have
been already sent. And at this point the delay account is still in
the state as if the new packets are just queued, so the driver gets
confused and spews the bogus error messages.
For fixing the issue, we just need to check whether the received
packet is valid, whether it's zero sized or not.

The pause and resume operations indicate that the stream can be
un-paused/resumed from the exact location they were paused/suspended.
This is not true for this driver, the pause and suspend triggers share
the same code path with stop, they flush all pending DMA transfers.
This drops all pending samples. The pause_release/resume triggers are
the same as start, except that prepare won't be called beforehand,
nothing will be enqueued to the DMA engine and nothing will happen (no
audio). Removing the pause flag will let apps know that it isn't
supported. Removing the resume flag will cause user space to call
prepare and start instead of resume, so audio will continue playing when
the system wakes up.
Before removing the pause and resume flags, I tested this on an exynos
5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a
write error. Suspend/resume testing led to the same result. Removing
the two flags fixes suspend/resume (since snd_pcm_prepare is called
again). And leads to a proper reporting of pause not supported.

Playback Designs' USB devices have some hardware limitations on their
USB interface. In particular:
- They need a 20ms delay after each class compliant request as the
hardware ACKs the USB packets before the device is actually ready
for the next command. Sending data immediately will result in buffer
overflows in the hardware.
- The devices send bogus feedback data at the start of each stream
which confuse the feedback format auto-detection.
This patch introduces a new quirks hook that is called after each
control packet and which adds a delay for all devices that match
Playback Designs' USB VID for now.
In addition, it adds a counter to snd_usb_endpoint to drop received
packets on the floor. Another new quirks function that is called once
an endpoint is started initializes that counter for these devices on

In order to support devices with implicit feedback streaming models,
packet sizes are now stored with each individual urb, and the PCM
handling code which fills the buffers purely relies on the size fields
now.
However, calling snd_usb_audio_next_packet_size() for all possible
packets in an URB at once, prior to letting the PCM code do its job
does in fact not lead to the same behaviour than what the old code did:
The PCM code will break its loop once a period boundary is reached,
consequently using up less packets that it really could.
As snd_usb_audio_next_packet_size() implements a feedback mechanism to
the endpoints phase accumulator, the number of calls to that function
matters, and when called too often, the data rate runs out of bounds.
Fix this by making the next_packet function public, and call it from the
PCM code as before if the packet data sizes are not defined.

v2: Fixed result still wrong in the case of 512 KiB DRAM. Oops.
Applicable to 3.5.3 mainline.
In emu8000.c, size_dram determines the amount of memory on the sound card by
doing write/readback tests starting at 512 KiB and incrementing by 512 KiB.
On success, detected_size is updated to the successful address and testing
continues. On failure, the loop is immediately exited. The resulting
detected_size is 512 KiB too small except in two special cases:
1. If there is no memory, the initial 0 value of detected_size is used, which
is correct.
2. If the address space wraps around, detected_size is updated before the
bailout, so the result is correct.
The patch corrects all cases and was tested with an AWE64 Gold. Before:
EMU8000 [0x620]: 3584 Kb on-board memory detected
asfxload 4GMGSMT.SF2 (4174814 B) fails.
After:
EMU8000 [0x620]: 4096 Kb on-board memory detected
asfxload 4GMGSMT.SF2 succeeds.
I do not have a card with 512 KiB to test with, but by forcibly enabling the
added conditional I verified on the AWE64 Gold that it detects 512 KiB
(successfully reading from the first memory location) and does not hang the
card.

Commit 412312 (ASoC: dapm: Make sure all dapm contexts are updated) means
that any DAPM context being updated will have the bias level automatically
set, including the card. We can't safely do this as the card callbacks are
called for each device context and so the management of the card bias is
more complex. Several multi-component cards rely on this behaviour.
Skip updates during the asynchronous run entirely. We should really do them
in the synchronous section but it's not 100% clear which values to pick as
the different DAPM contexts may have different bias levels.

Runtime PM can bring more power saving:
- When the controller is suspended, its parent device will also have a chance
to suspend.
- PCI subsystem can choose the lowest power state the controller can signal
wake up from. This state can be D3cold on platforms with ACPI PM support.
And runtime PM can provide a gerneral sysfs interface for a system policy
manager.
Runtime PM support is based on current HDA power saving implementation. The user
can enable runtime PM on platfroms that provide acceptable latency on transition
from D3 to D0.
Details:
- When both power saving and runtime PM are enabled:
-- If a codec supports 'stop-clock' in D3, it will request suspending the
controller after it enters D3 and request resuming the controller before
back to D0. Thus the controller will be suspended only when all codecs are
suspended and support stop-clock in D3.
-- User IO operations and HW wakeup signal can resume the controller back to
D0.
- If runtime PM is disabled, power saving just works as before.
- If power saving is disabled, the controller won't be suspended because the
power usage counter can never be 0.
More about 'stop-clock' feature:
If a codec can support targeted pass-through operations in D3 state when there
is no BCLK present on the link, it will set CLKSTOP flag in the supported power
states and report PS-ClkStopOk when entering D3 state. Please refer to HDA spec
section 7.3.3.10 Power state and 7.3.4.12 Supported Power State.

Introduce snd-cmi8328 driver for C-Media CMI8328-based sound cards, such as
AudioExcel AV500.
It supports PCM playback and capture (full-duplex) through wss_lib, gameport,
OPL3 and MPU401. The AV500 card has onboard Dream wavetable synth connected
to the MPU401 port and Aux 1 input internally which works too.
The CDROM interface is not supported (as the drivers for these CDROMs were
removed from the kernel some time ago).
A separate driver is needed because CMI8328 is completely different chip to
CMI8329/CMI8330. It's configured by magic registers (there's no PnP). Sound is
provided by a real WSS codec (CS4231A) and the SB part is just a SB Pro
emulation (for DOS games, useless for Linux).
When SB is enabled, the CMI8328 chip disables access to the WSS codec,
emulates SoundBlaster on one side and outputs sound data to the codec - so SB
and WSS can't work together with this card. The WSS codec can do full duplex
by itself so there's no need for crazy things like snd-cmi8330 does
(combining SB and WSS parts into one driver).

Initialize err before returning on failure, as done elsewhere in the
function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>

In the first case, the second test of whether retval is negative is
redundant. It is dropped and the previous and subsequent tests are
combined.
In the second case, add an initialization of retval on failure of ioremap.

Speed comes from get_user() in audio_ioctl(). We use it to set the "s"
variable before clamping it to valid values so it could lead to a divide
by zero bug.

The capture volume increases with the register value so it shouldn't be

Currently the microphone input source is not selectable as while there is
a DAPM widget it's not connected to anything so it won't be properly
instantiated. Add something more correct for the input structure to get
things going, even though it's not hooked into the rest of the routing
map and so won't actually achieve anything except allowing the relevant
register bits to be written.

If DRC coefficients are not configured via platform data then add bytes
controls for them instead so they can be configured by applications. This
is the normal means of controlling things like this for newer systems, we
maintain compatibility with platform data to avoid disruption to existing
systems.

A PCM capture stream on usb-audio causes a scheduling-while-atomic
BUG, as reported in the bugzilla entry below. It's because
snd_usb_endpoint_start() is called at first at trigger START for a
capture stream, and this function contains the left-over EP
deactivation codes. The problem doesn't happen for a playback stream
because the function is called at PCM prepare time, which can sleep.
This patch fixes the BUG by moving the EP deactivation code into the
PCM prepare callback.

The new omap-twl4030 handles the boards used the following drivers:
igep0020, omap3beagle, omap3evm and overo.
Remove these drivers since they are mostly identical and we already have
drop in replacement for all of them.
Note: Earlier patch added the needed code for the board files to retain the
audio support for boards I can identify that used one of the removed
drivers.
If I missed something please take a look at for example:
arch/arm/mach-omap2/board-omap3beagle.c on how add support for omap-twl4030
audio.

Machine driver to handle simple devices using twl4030 as audio codec.
The driver supports the following boards:
- Beagleboard or Devkit8000
- Gumstix Overo or CompuLab CM-T35/CM-T3730
- IGEP v2
- OMAP3EVM
All of these boards can be switched to use this driver since their setup is
identical.
Devicetree support for the omap-twl4030 machine driver also implemented.

Added a simple support of automute for the front HP jack to AD1882
stack model. Such an addition is basically an exception -- we really
want to avoid the static quirk codes, but AD1882 parser isn't still
ready for moving to the BIOS auto-parser yet. So, as a quick fix, I
merged it for now.
In near future, we really need the big clean up of patch_analog.c to
move on to the auto-parser...

Replace with a proper ifdef check of CONFIG_PM_SLEEP in hda_intel.c.
But other places in HD-audio driver are still marked with CONFIG_PM,
since these can be called for power-saving even without
CONFIG_PM_SLEEP.
