| | | | | | | | | | | | | | | | | | | | | | | | Currently we increment the number of RTD's per card during the DAI link bind. This can cause an incorrect RTD count when we cannot find a component and defer the probe (and hence perform the DAI link bind for the card again). Fix the count so that it is cleared before every card registration and bind attempt. Signed-off-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

| * ASoC: set idle_bias_off=1 for all platform DAPM contextsStephen Warren2012-04-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ASoC core currently defaults to using STANDBY rather than OFF for idle ASoC platform devices, which causes a permanent pm_runtime_get() on them. This keeps the device active unnecessarily. This can be especially problematic when the ASoC platform device and DAI device are the same device. The distinction between OFF and STANDBY is likely not relevant for ASoC platform drivers, since they aren't analog devices. So, solve this issue by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this turns out to be a problem, this value could be sourced from the snd_soc_platform_driver, similarly to soc_probe_codec(). Note: Prior to this change, this caused a large (10) runtime_active count for the Tegra I2S controller even when not in use, and a leak in that value as streams were started and stopped. This change probably hides a bug. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | simple_open: automatically convert to simple_open()Stephen Boyd2012-04-051-7/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op.

* ASoC: core: Add support for masking out parts of coefficient blocksMark Brown2012-02-211-7/+67
| | | | | | | | | | | | | | | | Chip designers frequently include things like the enable and disable controls for algorithms in the register blocks which also hold the coefficients. Since it's desirable to split out the enable/disable control from userspace the plain SND_SOC_BYTES() isn't optimal for these devices. Add a SND_SOC_BYTES_MASK() which allows a bitmask from the first word of the block to be excluded from the control. This supports the needs of devices I've looked at and lets us have a reasonably simple API. Further controls can be added in future if that's needed.

* ASoC: core: Add SND_SOC_BYTES control for coefficient blocksMark Brown2012-02-211-0/+49
| | | | | | | | | | | | | | | | | | Allow devices to export blocks of registers to the application layer, intended for use for reading and writing coefficient data which can't usefully be worked with by the kernel at runtime (for example, due to requiring complex and expensive calculations or being the results of callibration procedures). Currently drivers are using platform data to provide configurations for coefficient blocks which isn't at all convenient for runtime management or configuration development. Currently only devices using regmap are supported, an error will be generated for any attempt to work with a byte control on a non-regmap device. There's no fundamental block to other devices so support could be added if required. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>

* ASoC: dapm: Implement and instantiate DAI widgetsMark Brown2012-02-171-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to allow us to do smarter things with DAI links create DAPM widgets which directly represent the DAIs in the DAPM graph. These are automatically created from the DAIs as we probe the card with references held in both directions between the widget and the DAI. The widgets are not made available for direct instantiation by drivers, they are created automatically from the DAIs. Drivers should be updated to create stream routes using DAPM maps rather than by annotating AIF and DAC widgets with streams. In order to ease transition to this model from existing drivers we automatically create DAPM routes between the DAI widgets and the existing stream widgets which are started and stopped by the DAI widgets, though the old stream handling mechanism is still in place. This also has the nice effect of removing non-DAPM devices as any device with a DAI acquires a widget automatically which will allow future simplifications to the core DAPM logic. The intention is that in future the AIF and DAI widgets will gain the ability to interact such that we are able to manage activity on individual channels independantly rather than powering up and down the entire AIF as we do currently. Currently we only generate these for CODECs, mostly as I have no systems with non-CODEC DAPM to integrate with. It should be a simple matter of programming to add the additional hookup for these.

| * ASoC: core: Better support for idle_bias_off suspend ignoresMark Brown2012-01-311-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an idle_bias_off device is in any state other than off then it is still active for some reason (typically a low power function such as accessory detection). This wasn't an issue when the feature was implemented as we always went to _ON for any active function, subsequent power improvements have changed things. With the modern way of doing things we should overhaul the infrastructure to allow devices to explicitly take references for these functions but that's a much more invasive change and will require driver updates to deploy, this will bring the framework into line with the existing driver set before we do that work.

* | ASoC: core: Add support for DAI and machine kcontrols.Liam Girdwood2012-02-041-38/+70

It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for SoC card machine drivers too. This allows the kcontrol to have a direct handle to the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily get it's private data. This change makes snd_soc_add_controls() static and wraps it in the folowing calls (card and dai are new) :- snd_soc_add_card_controls() snd_soc_add_codec_controls() snd_soc_add_dai_controls() snd_soc_add_platform_controls() This patch also does a lot of small mechanical changes in individual codec drivers to replace snd_soc_add_controls() with snd_soc_add_codec_controls(). It also updates the McBSP DAI driver to use snd_soc_add_dai_controls(). Finally, it updates the existing machine drivers that register controls to either :- 1) Use snd_soc_add_card_controls() where no direct codec control is required. 2) Use snd_soc_add_codec_controls() where there is direct codec control. In the case of 1) above we also update the machine drivers to get the correct component data pointers from the kcontrol (rather than getting the machine pointer via the codec pointer).

When instantiating sound cards from device tree, it may be more convenient to refer to these devices by phandle in the device tree, and for code to describe DAI links using the "struct device_node *" ("of_node") those phandles map to. This change adds new fields to snd_soc_dai_link which can "name" devices using of_node, enhances soc_bind_dai_link() to allow binding based on of_node, and enhances snd_soc_register_card() to ensure that illegal combinations of name and of_node are not used.

* ASoC: Implement fully_routed card propertyStephen Warren2011-11-231-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | A card is fully routed if the DAPM route table describes all connections on the board. When a card is fully routed, some operations can be automated by the ASoC core. The first, and currently only, such operation is described below, and implemented by this patch. Codecs often have a large number of external pins, and not all of these pins will be connected on all board designs. Some machine drivers therefore call snd_soc_dapm_nc_pin() for all the unused pins, in order to tell the ASoC core never to activate them. However, when a card is fully routed, the information needed to derive the set of unused pins is present in card->dapm_routes. In this case, have the ASoC core automatically call snd_soc_dapm_nc_pin() for each unused codec pin. This has been tested with soc/tegra/tegra_wm8903.c and soc/tegra/trimslice.c.

Yet its counterpart snd_soc_resume() does not check this, causing complaints about spinlock lockup: [ 176.726087] BUG: spinlock lockup on CPU#0, kworker/0:2/1067, d8ab82a8 [ 176.732539] [<80014a14>] (unwind_backtrace+0x0/0xec) from [<805b3fc8>] (dump_stack+0x20/0x24) [ 176.741082] [<805b3fc8>] (dump_stack+0x20/0x24) from [<80322208>] (do_raw_spin_lock+0x118/0x158) [ 176.749882] [<80322208>] (do_raw_spin_lock+0x118/0x158) from [<805b7874>] (_raw_spin_lock_irqsave+0x5c/0x68) [ 176.759723] [<805b7874>] (_raw_spin_lock_irqsave+0x5c/0x68) from [<8002a020>] (__wake_up+0x2c/0x5c) [ 176.768781] [<8002a020>] (__wake_up+0x2c/0x5c) from [<804a6de8>] (soc_resume_deferred+0x3c/0x2b0) [ 176.777666] [<804a6de8>] (soc_resume_deferred+0x3c/0x2b0) from [<8004ee20>] (process_one_work+0x2e8/0x50c) [ 176.787334] [<8004ee20>] (process_one_work+0x2e8/0x50c) from [<8004fd08>] (worker_thread+0x1c8/0x2e0) [ 176.796566] [<8004fd08>] (worker_thread+0x1c8/0x2e0) from [<80053ec8>] (kthread+0xa4/0xb0) [ 176.804843] [<80053ec8>] (kthread+0xa4/0xb0) from [<8000ea70>] (kernel_thread_exit+0x0/0x8) Signed-off-by: Eric Miao <eric.miao@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen2011-11-231-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Fix prefixing of DAPM controlsMark Brown2011-10-181-3/+3

* ASoC: Suppress early calls to snd_soc_dapm_sync()Mark Brown2011-10-081-0/+1
| | | | | | | | | | Ensure we only have one sync during the initial startup of the card by making snd_soc_dapm_sync() a noop on non-instantiated cards. This avoids any bounces due to things like jacks reporting their initial state on partially initialised cards. The callers that don't also get called at runtime should just be removed.

* ASoC: Do DAPM power checks only for widgets changed since last runMark Brown2011-10-041-0/+1
| | | | | | | | | | | | | | | | | | | | In order to reduce the number of DAPM power checks we run keep a list of widgets which have been changed since the last DAPM run and iterate over that rather than the full widget list. Whenever we change the power state for a widget we add all the source and sink widgets it has to the dirty list, ensuring that all widgets in the path are checked. This covers more widgets than we need to as some of the neighbour widgets won't be connected but it's simpler as a first step. On one system I tried this gave: Power Path Neighbour Before: 207 1939 2461 After: 114 1066 1327 which seems useful. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
