Subject: ASoC: core: Move the default regmap I/O setting to
snd_soc_register_codec()
Add the default regmap I/O setting to snd_soc_register_codec() while
the CODEC is initialising, which will be called by CODEC driver device
probe(), and then we can make XXX_set_cache_io() go away entirely from each
CODEC ASoC probe.

Subject: ASoC: codec: fix the sparse check warnings.
Some thing Likes:
reproduce: make C=1 CF=-D__CHECK_ENDIAN__
sparse warnings: (new ones prefixed by >>)
>> sound/soc/codecs/wm8997.c:1084:15: sparse: symbol \
'wm8997_get_regmap' was not declared. Should it be static?

From ea53bf77d147e7e560ac007fdaa30fb98c37c712 Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen

Subject: ASoC: Add snd_soc_kcontrol_codec() helper function
For CODEC controls snd_kcontrol_chip() currently returns a pointer to the
CODEC that registered the control. With the upcoming consolidation of
platform and CODEC controls this will change. Prepare for this by introducing
the snd_soc_kcontrol_codec() helper function that will hide the implementation
details of how the CODEC for a control can be obtained. This will allow us to
change this easily in the future.
The patch also updates all CODEC drivers to use the new helper function.

From f6272ff8a5f42c614f4a338013f5323979121e0f Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen
Date: Tue, 18 Mar 2014 09:02:05 +0100
Subject: ASoC: Add snd_soc_kcontrol_platform() helper function
For platform controls snd_kcontrol_chip() currently returns a pointer to the
platform that registered the control. With the upcoming consolidation of
platform and CODEC controls this will change. Prepare for this by introducing
the snd_soc_kcontrol_platform() helper function that will hide the
implementation details of how the platform for a control can be obtained. This
will allow us to change this easily in the future.
The patch also updates all platforms to use this new helper function.

Subject: ASoC: Prepare SOC_SINGLE_XR_SX controls for regmap
SOC_SINGLE_XR_SX controls currently only work with CODECs that set the
'reg_word_size' field in their snd_soc_codec_driver struct. Going forward
support for ASoC level IO will eventually be removed and all drivers will be
converted to regmap. Preparing for the transition this patch adds support for
CODECs using regmap for IO to the SOC_SINGLE_XR_SX control. We already have the
val_bytes field in the CODEC struct which holds the number of bytes per word,
but it is only initialized when regmap is used. Also initialize it for drivers
still using legacy IO and update the SOC_SINGLE_XR_SX handlers to use it.

Subject: ASoC: Track which components have been registered with
snd_soc_register_component()
snd_soc_unregister_component() takes the parent device of the component as a
parameter and then looks up the component based on this. This is a problem if
multiple components are registered for the same parent device. Currently drivers
do not do this, but some drivers register a CPU DAI component and a platform for
the same parent device. This will become a problem once platforms are also made
components. To make sure that snd_soc_unregister_component() will not
accidentally unregister the platform in such a case only consider components
that were registered with snd_soc_register_component(). This is only meant as
short term stopgap solution to be able to continue componentisation. Long term
we'll need something different.

Subject: ASoC: Let snd_soc_platform subclass snd_soc_component
There is an increasing amount of code that is very similar between platforms,
CODECS and other components. Making platforms a component will allow us to
share this code. For now the patch just adds component and component_driver
fields to the platform and platform_driver structs and registers the platform as
a component. Followup patches will be used to consolidate code between the
different types of components.

Subject: ASoC: sta350: Add codec driver
The TI STA350 is an integrated 2.1-channel power amplifier that is
controllable over I2C. This patch adds an ASoC driver for it.
At a glance, this chip is very similar to the STA320 for which a driver
already exists. In details, however, the register maps contain subtle
differences which made a whole new driver easier to write and maintain.

+STA350 audio CODEC
+
+The driver for this device only supports I2C.
+
+Required properties:
+
+ - compatible: "st,sta350"
+ - reg: the I2C address of the device for I2C
+ - reset-gpios: a GPIO spec for the reset pin. If specified, it will be
+ deasserted before communication to the codec starts.
+
+ - power-down-gpios: a GPIO spec for the power down pin. If specified,
+ it will be deasserted before communication to the codec
+ starts.
+
+ - vdd-dig-supply: regulator spec, providing 3.3V
+ - vdd-pll-supply: regulator spec, providing 3.3V
+ - vcc-supply: regulator spec, providing 5V - 26V
+
+Optional properties:
+
+ - st,output-conf: number, Selects the output configuration:
+ 0: 2-channel (full-bridge) power, 2-channel data-out
+ 1: 2 (half-bridge). 1 (full-bridge) on-board power
+ 2: 2 Channel (Full-Bridge) Power, 1 Channel FFX
+ 3: 1 Channel Mono-Parallel
+ If parameter is missing, mode 0 will be enabled.
+
+ - st,ch1-output-mapping: Channel 1 output mapping
+ - st,ch2-output-mapping: Channel 2 output mapping
+ - st,ch3-output-mapping: Channel 3 output mapping
+ 0: Channel 1
+ 1: Channel 2
+ 2: Channel 3
+ If parameter is missing, channel 1 is choosen.
+
+ - st,thermal-warning-recover:
+ If present, thermal warning recovery is enabled.
+
+ - st,thermal-warning-adjustment:
+ If present, thermal warning adjustment is enabled.
+
+ - st,fault-detect-recovery:
+ If present, then fault recovery will be enabled.
+
+ - st,ffx-power-output-mode: string
+ The FFX power output mode selects how the FFX output timing is
+ configured. Must be one of these values:
+ - "drop-compensation"
+ - "tapered-compensation"
+ - "full-power-mode"
+ - "variable-drop-compensation" (default)
+
+ - st,drop-compensation-ns: number
+ Only required for "st,ffx-power-output-mode" ==
+ "variable-drop-compensation".
+ Specifies the drop compensation in nanoseconds.
+ The value must be in the range of 0..300, and only
+ multiples of 20 are allowed. Default is 140ns.
+
+ - st,overcurrent-warning-adjustment:
+ If present, overcurrent warning adjustment is enabled.
+
+ - st,max-power-use-mpcc:
+ If present, then MPCC bits are used for MPC coefficients,
+ otherwise standard MPC coefficients are used.
+
+ - st,max-power-corr:
+ If present, power bridge correction for THD reduction near maximum
+ power output is enabled.
+
+ - st,am-reduction-mode:
+ If present, FFX mode runs in AM reduction mode, otherwise normal
+ FFX mode is used.
+
+ - st,odd-pwm-speed-mode:
+ If present, PWM speed mode run on odd speed mode (341.3 kHz) on all
+ channels. If not present, normal PWM spped mode (384 kHz) will be used.
+
+ - st,distortion-compensation:
+ If present, distortion compensation variable uses DCC coefficient.
+ If not present, preset DC coefficient is used.
+
+ - st,invalid-input-detect-mute:
+ If not present, automatic invalid input detect mute is enabled.
+
+
+
+Example:
+
+codec: sta350@38 {
+ compatible = "st,sta350";
+ reg = <0x1c>;
+ reset-gpios = <&gpio1 19 0>;
+ power-down-gpios = <&gpio1 16 0>;
+ st,output-conf = <0x3>; // set output to 2-channel
+ // (full-bridge) power,
+ // 2-channel data-out
+ st,ch1-output-mapping = <0>; // set channel 1 output ch 1
+ st,ch2-output-mapping = <0>; // set channel 2 output ch 1
+ st,ch3-output-mapping = <0>; // set channel 3 output ch 1
+ st,max-power-correction; // enables power bridge
+ // correction for THD reduction
+ // near maximum power output
+ st,invalid-input-detect-mute; // mute if no valid digital
+ // audio signal is provided.

Subject: ASoC: core: Add helpers for codec and codec_dai search
Add dedicated helpers for codec and codec_dai search in preparation
for DAI-multicodec. It will help reducing the extra indentation
that will be introduced by the iteration over multiple codecs.
Previous implementation unnecessarily kept searching for a matching
codec in the remaining register codecs even if it was already found.
Fix that by returning in case of matching.

Subject: ASoC: Move IO abstraction to the component level
We currently have two very similar IO abstractions in ASoC, one for CODECs, the
other for platforms. Moving this to the component level will allow us to unify
those two. It will also enable us to move the standard kcontrol helpers as well
as DAPM support to the component level.
The new component level abstraction layer is primarily build around regmap.
There is a per component pointer for the regmap instance for the underlying
device. There are four new function snd_soc_component_read(),
snd_soc_component_write(), snd_soc_component_update_bits() and
snd_soc_component_update_bits_async(). They have the same signature as their
regmap counter-part and will internally forward the call one-to-one to regmap.
If the component it not using regmap it will fallback to using the custom IO
callbacks. This is done to be able to support drivers that haven't been
converted to regmap yet, but it is expected that this will eventually be removed
in the future once all component drivers have been converted to regmap.

Subject: ASoC: Remove ASoC level IO tracing
The ASoC framework is in the process of migrating all IO operations to regmap.
regmap has its own more sophisticated tracing infrastructure for IO operations,
which means that the ASoC level IO tracing becomes redundant, hence this patch
removes them. There are still a handful of ASoC drivers left that do not use
regmap yet, but hopefully the removal of the ASoC IO tracing will be an
additional incentive to switch to regmap.

Subject: ASoC: Move standard kcontrol helpers to the component level
After moving the IO layer inside ASoC to the component level we can now easily
move the standard control helpers also to the component level. This allows to
reuse the same standard helper control implementations for other components.

From 4da533932dedff930596bc536adaba1e508f9ffa Mon Sep 17 00:00:00 2001

Subject: ASoC: core: Fix component_list corruption when unloading modules
This fixes module unload regressions introduced by commits 98e639fb8a3e
("ASoC: Track which components have been registered with
snd_soc_register_component()") and b37f1d123c69 ("ASoC: Let snd_soc_platform
subclass snd_soc_component").
First commit causes component_list to be corrupted when removing codec and
second when removing platform. Reason for both is that components associated
with platform or codec are never removed from the list because for them
registered_as_component field in struct snd_soc_component is always false.
Now list becomes corrupted when snd_soc_unregister_platform() or
snd_soc_unregister_codec() frees the platform or codec structure and where
the associated struct snd_soc_component is embedded.
Fix these by moving component unregistration and cleanup to a new local
function __snd_soc_unregister_component() that takes component as its
argument.
Since component is known for platforms and codecs the
__snd_soc_unregister_component() can be called directly and
snd_soc_unregister_component() takes care to find and unregister only
components that were registered using snd_soc_register_component().
