e6b5be2be4 Driver core patches for 3.19-rc1
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.

20feb88198 ASoC: Add helper functions for deferred regmap setup
Some drivers (most notably the AC'97 drivers) do not have access to their
regmap struct when the component/codec is registered. For those drivers the
automatic regmap setup will not work and needs to be done manually,
typically from the component/CODEC drivers probe callback.

This patch adds a set of helper function to handle deferred regmap
initialization as well as early regmap tear-down.

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
	=

6794f709b7 ASoC: ac97: Drop delayed device registration
We have all the information and dependencies we need to initialize and
register the device available in snd_soc_new_ac97_codec(). So there is no
need to delay the device registration until after the card itself as been
registered.

This makes the code significantly simpler and also makes it possible to use
the AC'97 device in the CODECs probe function. The later will be required to
be able to convert the AC'97 CODEC drivers to regmap.

70f3af3ca1 ASoC: Properly handle AC'97 device lifetime management
The memory that a struct device is contained in must not be freed except
from within the device's release callback. The ASoC code currently does not
adhere to this rule for the AC'97 device. This patch fixes it by moving the
freeing of the AC'97 to the release callback and splitting up the
registration and unregistration of the device into separate steps for
getting/putting the reference to the device and adding/removing it to the
device hierarchy.

1ffae3612f ASoC: Fix snd_soc_find_dai() matching component by name
Commit 14621c7e5e ("ASoC: Consolidate CPU and CODEC DAI lookup")
consolidated the lookup of CPU DAIs and CODEC DAIs into a single function.
When matching a component by name for CODEC DAIs the code previous to the
patch compared the name in the DAI link table with component->name. For CPU
DAIs the code compared to dev_name(component->dev). The newly introduced
function ended up using the later as well.

For most components dev_name(component->dev) and component->name are the
same. The main notable exception are I2C devices where the driver name and
the device name are concatenated to form the component name. By using
dev_name(component->dev) instead of component->name the patch broke the
matching of I2C CODECs by name.

This patch restores the original behavior by using component->name instead
of dev_name(component->dev). This will be safe even for CPU DAIs since for
CPU DAIs both are the same.

8be4da29cf ASoC: dapm: Mark endpoints instead of IO widgets dirty during suspend/resume
The state of endpoint widgets is affected by that card's power state.
Endpoint widgets that do no have the ignore_suspend flag set will be
considered inactive during suspend. So they have to be re-checked and marked
dirty after the card's power state changes. Currently the input and output
widgets are marked dirty instead, this works most of the time since
typically a path from one endpoint to another will go via a input or output
widget. But marking the endpoints dirty is technically more correct and will
also work for odd corner cases.

the range sent to the hardware is 40..255, but in the invert case:

a80932979a ASoC: Always run default suspend/resume code
We do a bit more than just running the callbacks during suspend and resume

only when suspend and resume callbacks are specified for the driver,
otherwise nothing is done. This means that drivers which don't want to do
anything special during suspend and resume, but still want the standard
operations to run, need to provide empty suspend and resume callback
functions (rather than no callbacks). This patch updates the suspend and

86dbf2ac6f ASoC: Add support for automatically going to BIAS_OFF on suspend
There is a substantial amount of drivers that in go to SND_SOC_BIAS_OFF on
suspend and go back to SND_SOC_BIAS_SUSPEND on resume (Often this is even

introduces a new suspend_bias_off flag, which when set by a driver will let
the ASoC core automatically put the device's DAPM context at the
SND_SOC_BIAS_OFF level during suspend. Once the device is resumed the DAPM
context will go back to SND_SOC_BIAS_STANDBY (if the context is idle,
otherwise to SND_SOC_BIAS_ON).

This will allow us to remove a fair bit of duplicated code from the drivers.

Currently when a ASoC sound card is unregistered we leave the individual

This patch introduces a call to snd_soc_dapm_shutdown() when removing the

and all DAPM contexts are put at the SND_SOC_BIAS_OFF level. This will
ensure that all components are properly powered down when the card is
removed.

Since a lot of drivers manually go to SND_SOC_BIAS_OFF in their remove
callback this will also allow us to remove a bit of duplicated code.

c5599b87a8 ASoC: Replace list_empty(&card->codec_dev_list) with !card->instantiated

card->instantiated to check if the card has been instantiated yet.
