ASoC: wm8903: Update to use maple tree register cache The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wm8903 driver to use the more modern data structure.

i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

ASoC: wm8903: add regulator handling The WM8903 has four different voltage inputs: AVDD, CPVDD, DBVDD and DCVDD. On the Qualcomm APQ8060 Dragonboard these are all supplied from proper regulators and thus need activating and binding. This is a quick-and-dirty solution just grabbing and enabling the regulator supplies on probe() and disabling them on remove() and the errorpath. More elaborate power management is likely possible. I assume the nVidia designs using this codec have some hard-wired always-on power and will be happy with using the dummy regulators for this. But someone from the nVidia camp should probably check whether they can bind these to proper regulators instead. We also amend the DT binding document. A small change like this does not warrant a separate patch for augmenting these.

gpio: change member .dev to .parent The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

This makes the code a bit shorter and cleaner. Since the ASoC core now takes care of setting the bias level to SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually anymore either. The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe() can also be removed as the core will automatically do this after the CODEC has been probed. Also remove the unused codec field from the wm8903_priv struct so we can remove the whole probe callback.

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.

ASoC: WM8903: Get default irq_active_low from IRQ controller If the WM8903 is hooked up to an interrupt, set the irq_active_low flag in the default platform data based on the IRQ's IRQ_TYPE. Map IRQ_TYPE_NONE (a lack of explicit configuration/restriction) to irq_active_low = false; the previous default. This code is mainly added to support device tree interrupt bindings, although will work perfectly well in a non device tree system too. Any interrupt controller that supports only a single IRQ_TYPE could set each IRQ's type based on that restriction. This applies equally with and without device tree. To cater for interrupt controllers that don't do this, for which irqd_get_trigger_type() will return IRQ_TYPE_NONE, the platform data irq_active_low field may be used in systems that don't use device tree. With device tree, every IRQ must have some IRQ_TYPE set. Controllers that support DT and multiple IRQ_TYPEs must define the interrupts property (as used in interrupt source nodes) such that it defines the IRQ_TYPE to use. When the core DT setup code initializes wm8903->irq, the interrupts property will be parsed, and as a side- effect, set the IRQ's IRQ_TYPE for the WM8903 probe() function to read. Controllers that support DT and a single IRQ_TYPE could arrange to set the IRQ_TYPE somehow during their initialization, or hard-code it during the processing of the child interrupts property.

ASoC: WM8903: Remove conditionals checking pdata != NULL The pdata pointer is now always valid. Remove any conditions that check its validity. This patch is mostly just removing an indentation level. One variable had to be moved due to the removal of a scope, and one comment was split into two. Viewing the patch with git show/diff -b will show that it's actually very small. Note that WM8903_MIC_BIAS_CONTROL_0 is now written unconditionally, whereas it used to be written only if pdata was supplied. Since defpdata.micdet_cfg = 0, this unconditional write simply echos the HW defaults in the case where pdata is not supplied. Based on work by John Bonesio, but significantly reworked since then.

ASoC: WM8903: Fix platform data gpio_cfg confusion wm8903_platform_data.gpio_cfg[] was intended to be interpreted as follows: 0: Don't touch this GPIO's configuration register 1..7fff: Write that value to the GPIO's configuration register 8000: Write zero to the GPIO's configuration register other: Undefined (invalid) The rationale is that platform data is usually global data, and a value of zero means that the field wasn't explicitly set to anything (e.g. because the field was new to the pdata type, and existing users weren't update to initialize it) and hence the value zero should be ignored. 0x8000 is an explicit way to get 0 in the register. The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs through gpiolib", where the behaviour was changed due to my lack of awareness of the above rationale. This patch reverts to the intended behaviour, and updates all in-tree users to use the correct scheme. This also makes WM8903 consistent with other devices that use a similar scheme. WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that its name accurately reflects its purpose.

ASoC: WM8903: Implement DMIC support In addition to the currently supported analog capture path, the WM8903 also supports digital mics. The analog and digital capture paths are exclusive; a mux is present to select the capture source. Logically, the mux exists to select the decimator's input, from either the ADC or DMIC block outputs. However, the ADC power domain also includes the DMIC interface. Consequently, this change represents the mux as existing immediately before the ADC, and selecting between the Input PGA and DMIC block outputs. An alternative might be to represent the mux in its correct location, and associate the ADC power enable controls with both the real ADC, and a fake ADC for the DMIC?

ASoC: Decouple DAPM from CODECs Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes.

ASoC: multi-component - ASoC Multi-Component Support This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().

ASoC: Add indirection for CODEC private data One of the features of the multi CODEC work is that it embeds a struct device in the CODEC to provide diagnostics via a sysfs class rather than via the device tree, at which point it's much better to use the struct device private data rather than having two places to store it. Provide an accessor function to allow this change to be made more easily, and update all the CODEC drivers are updated. To ensure use of the accessor the private data structure member is renamed, meaning that if code developed with older an older core that still uses private_data is merged it will fail to build.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

ASoC: make ops a pointer in 'struct snd_soc_dai' Considering the fact that most cpu_dai or codec_dai are using a same 'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better made a pointer instead, to make sharing easier and code a bit cleaner. The patch below is rather preliminary since the asoc tree is being actively developed, and this touches almost every piece of code, (and possibly many others in development need to be changed as well). Building of all codecs are OK, yet to every SoC, I didn't test that.

ASoC: cleanup duplicated code. Many codec drivers were implementing cookie-cutter copies of the function that adds kcontrols to the codec. This patch moves this code to a common function snd_soc_add_controls() in soc-core.c and updates all drivers using copies of this function to use the new common version.

ASoC: Register non-AC97 codec DAIs Currently this is done at module probe time since ASoC ties in codec device probe to the instantiation of the entire ASoC device. Subsequent patches will refactor the codec drivers to handle probing separately. Note that the core does not yet use this information. AC97 is special since the codec is controlled over the AC97 link but we want to give the machine driver a chance to set up the system before trying to instantiate since it may need to do configuration before the AC97 link will operate Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

As part of the work to allow independant registration of cards, codecs and machines in ASoC v2 a new function of the same name has been added so rename the existing function to facilitate the merge of v2.

ASoC: Merge snd_soc_ops into snd_soc_dai_ops Liam Girdwood's ASoC v2 work avoids having two different ops structures for DAIs by merging the members of struct snd_soc_ops into struct snd_soc_dai_ops, allowing per DAI configuration for everything. Backport this change. This paves the way for future work allowing any combination of DAIs to be connected rather than having fixed purpose CODEC and CPU DAIs and only allowing CODEC<->CPU interconnections.
