92ac4c5012 ASoC: z2: Automatically disconnect non-connected pins
Most DAPM input and output pins of the wm8750 are either used in the card's
DAPM routing table or are marked as not connected. The only exceptions are
the LINPUT1, RINPUT1, LINPUT2 input pins. Lets assume that those were
simply overlooked and that the routing table is complete.

Set the fully_routed flag of the card instead of manually marking the
unused inputs and outputs as not connected. This makes the code a bit
shorter and cleaner.

9b44bacd58 ASoC: poodle: Automatically disconnect non-connected pins
The Zaurus SL-5600 seems to have a microphone input. Otherwise all DAPM
input and output pins of the wm8731 are either used in the card's DAPM
routing table or are marked as not connected.

So add the microphone to the DAPM tables and set the fully_routed flag of
the card instead of manually marking the unused inputs and outputs as not
connected. This makes the code a bit shorter and cleaner.

Most DAPM input and output pins of the wm8994 are either used in the card's
DAPM routing table or are marked as not connected.

The only exception is DMIC2DAT input. Given that DMIC1DAT is explicitly
mentioned in the DAPM routes lets assume that DMIC2DAT simply has been
overlooked and should be marked as not connected.

7c47cd7ffd ASoC: pxa: make TTC DKB tristate
In a rare combination of Kconfig settings, the 88pm860x-codec
module may be selected as a loadable module, while it's also being
used by the ttb-dkb code that is built-in, resulting in a link
error:

sound/built-in.o: In function `ttc_pm860x_init':
:(.text+0x3e888): undefined reference to `pm860x_hs_jack_detect'
:(.text+0x3e898): undefined reference to `pm860x_mic_jack_detect'

Changing ttb-tkb to a tristate option tells Kconfig that 88pm86x
actually needs to be built-in if ttc-dkb is also built-in.

Commit f6b2a04590 ("ASoC: pxa: mioa701_wm9713: Convert to table based DAPM
setup") converted the driver to register the board level DAPM elements with
the card's DAPM context rather than the CODEC's DAPM context. The change
overlooked that the speaker widget event callback accesses the widget's
codec field which is only valid if the widget has been registered in a CODEC
DAPM context. This patch modifies the callback to take an alternative route
to get the CODEC.

Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

bc26321404 ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_control
Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.

While we are at it also change the type from int to bool.

The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>
@@
identifier drv;
@@
struct snd_soc_dai_driver drv = {
-	.ac97_control
+	.bus_control
	=
-	1
+	true
};

5ab0862e5d ASoC: MMP audio needs sram support
From e7a94bb7fb871c73cc85712d89c1f48d0271c1be Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Thu, 5 Jun 2014 12:31:28 +0200
Subject: [PATCH] ASoC: MMP audio needs sram support

Building the pxa/mmp audio driver without support for the mmp
sram driver enabled results in this link error:

sound/built-in.o: In function `mmp_pcm_free_dma_buffers':
:(.text+0x3e734): undefined reference to `sram_get_gpool'
sound/built-in.o: In function `mmp_pcm_new':
:(.text+0x3e7c0): undefined reference to `sram_get_gpool'

The sram driver is cannot be manually enabled and needs to
be turned on by selecting MMP_SRAM from each module that
needs it, which is what this patch does.

Ideally, MMP should move over to the generic SRAM support, but
for the moment, we can avoid the build error.

38784764bb ASoC: pxa: add I2C dependencies as needed
We have in the past added 'depends on I2C' for some of the PXA boards
after hitting randconfig build bugs. I have seens a couple of new
bugs in this area during the linux-next cycle for 3.16, after it
became possible to build some more PXA machines with I2C disabled.

To shut this up for good, this adds the dependency to every board
that uses I2C as the interface to the codec. I have gone through
all board files and verified that they all either use AC97 or
I2C, and this annotates the latter. Some of these already enable
I2C from mach-pxa/Kconfig, but since that can change it's better
to be explicit here.

The link error that can result otherwise happens when CONFIG_I2C
is set to 'm' and the codec driver is built-in as a result of being
selected by the platform specific glue.

16088cb6c0 ASoC: Fix wrong argument for card remove callbacks
The commit [e1d4d3c8: ASoC: free jack GPIOs before the sound card is
freed] introduced snd_soc_card remove callbacks to a few drivers, but
they are implemented with a wrong argument type.  The callback should
receive snd_soc_card pointer instead of snd_soc_pcm_runtime.

Fixes: e1d4d3c854 ('ASoC: free jack GPIOs before the sound card is freed')

e1d4d3c854 ASoC: free jack GPIOs before the sound card is freed
This is the same change as commit fb6b8e7144 "ASoC: tegra: free jack
GPIOs before the sound card is freed", but applied to all other ASoC
machine drivers where code inspection indicates the same problem exists.

That commit's description is:
==========
snd_soc_jack_add_gpios() schedules a work queue item to poll the GPIO to
generate an initial jack status report. If sound card initialization
fails, that work item needs to be cancelled, so it doesn't run after the
card has been freed. Specifically, freeing the card calls
snd_jack_dev_free() which calls snd_jack_dev_disconnect() which sets
jack->input_dev = NULL, and input_dev is used by snd_jack_report(), which
is called from the work queue item.

snd_soc_jack_free_gpios() cancels the work item. The Tegra ASoC machine
drivers do call this function in the platform driver remove() callback.
However, this happens after the sound card is freed, at least when the
card is freed due to errors late during snd_soc_instantiate_card(). This
leaves a window where the work item can execute after the card is freed.
In next-20140522, sound card initialization does fail for unrelated
reasons, and hits the problem described above.

To solve this, fix the Tegra ASoC machine drivers to clean up the Jack
GPIOs during the snd_soc_card's .remove() callback, which is executed
before the overall card object is freed. also, guard the cleanup call
based on whether we actually setup up the GPIOs in the first place.
Ideally, we'd do the cleanup in a struct snd_soc_dai_link .fini/remove
function to match where the GPIOs get set up. However, there is no such
callback.
==========

Note that I have not even compile-tested this in most cases, since most
of the drivers rely on specific mach-* support I don't have enabled, and
don't support COMPILE_TEST. Testing by the relevant board maintainers
would be useful.

b45281412a ASoC: pxa: remove mach header dependency
As we are moving the mmp platform towards multiplatform support,
we have to stop including platform header files.

This changes the pxa-ssp sound driver file to no longer depend
on mach/hardware.h and mach/dma.h. The code using the definitions
from those headers is actually gone already, the only thing
that was still being used was the pxa_dma_desc typedef, which
we can easily work around by using the normal 'struct pxa_dma_desc'
name.

The pxa2xx-dma driver still uses this header, so we include it
explicitly there, which is ok because that is only used on pxa,
not on mmp.

d77a14b579 ASoC: Remove needless snd_soc_dapm_enable_pin() from machine driver inits
ALSA SoC core marks widgets as connected by default when they are
initialized in snd_soc_dapm_new_control() so there is no need to call
snd_soc_dapm_enable_pin() from machine driver init functions.
