2014-03-12ASoC: Fix use after freeLars-Peter Clausen1-2/+3
Freeing the current list element while iterating over the list will cause a use after free since the iterator function will still use the current element to look up the next. Use list_for_each_safe() and remove the element from the list before freeing it to avoid this.

2014-03-10ASoC: Add a per component dai listLars-Peter Clausen1-42/+34
Now that every DAI has a component we can track the DAIs on a per component basis. This simplifies the DAI lookup when we are only interested in DAIs of a specific component and also makes it possible to have multiple components with the same parent device and also register DAIs.

2014-03-10ASoC: Pass CODEC to snd_soc_register_dais()Lars-Peter Clausen1-17/+11
snd_soc_register_dais() looks up the CODEC that is registering the DAIs by looping over all registered CODECs. This patch updates the code to simply pass the CODEC that registers the DAIs to snd_soc_register_dais() thus avoiding the lookup.

2014-03-10ASoC: Consolidate snd_soc_register_dai() and snd_soc_register_dais()Lars-Peter Clausen1-112/+42
snd_soc_register_dais() has basically the same code as snd_soc_register_dai(), but running in a loop. The only difference is that snd_soc_register_dai() calls fmt_single_name() to generate the DAIs name and snd_soc_register_dais() calls fmt_multiple_name(). This patch pushes the check in __snd_soc_register_component() which decides whether to call snd_soc_register_dai() or snd_soc_register_dais() to snd_soc_register_dais() to decide which naming scheme to use. This allows us to remove snd_soc_register_dai(). The patch also updates snd_soc_register_dais() to unregister every DAI it finds for the component rather than trying to unregister one DAI for each DAI that was registered. Both have the same result since there won't be more DAIs than what have been registered, but the former is easier to implement.

2014-03-06ASoC: core: use regmap's parse_val to do endian translationNenghua Cao1-5/+29
In snd_soc_bytes_put function, it forces cpu to do cpu_to_be translation, but for mmio bus which uses REGMAP_ENDIAN_NATIVE, it doesn't need to do endian translation. So it is better to use regmap's api which can decide if this translation is needed according to bus configuration.

2014-03-01ASoC: Consolidate enum and value enum controlsLars-Peter Clausen1-85/+16
The implementations for enum and value enum controls are almost identical. The only difference is that the value enum uses an additional look-up table to map the control value to the register value, while the enum control uses a direct mapping. Enums and value enums can easily be distinguished at runtime, for value enums the values field of the snd_soc_enum struct contains the look-up table, while for enums it is NULL. This patch adds two new small helper functions called snd_soc_enum_item_to_val() and snd_soc_enum_val_to_item() which map between register value and control item. If the items field of the snd_soc_enum struct is NULL the function will do a direct mapping otherwise they'll use the look-up table to do the mapping. Using these small helper functions it is possible to use the same kcontrol handlers for both enums and value enums. The functions are added a inline functions in soc.h so they can also be used by the DAPM code to accomplish similar consolidation.

2014-02-23ASoC: core: add TDM slot parsing from DT supportsXiubo Li1-0/+59
For some CPU/CODEC DAI devices the TDM slot infomation maybe needed. This patch adds the slot parsing from DT supports. TDM slot properties: dai-tdm-slot-num : Number of slots in use. dai-tdm-slot-width : Width in bits for each slot. For instance: dai-tdm-slot-num = <2>; dai-tdm-slot-width = <8>; And for each spcified driver, there could be one .of_xlate_tdm_slot_mask() to specify a explicit mapping of the channels and the slots. If it's absent the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the tx and rx masks. For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit for an active slot as default, and the default active bits are at the LSB of the masks.

2014-02-20ASoC: Rename soc_enum.max field with itemsTakashi Iwai1-9/+9
The name "max" in struct soc_enum is rather confusing since it actually takes the number of items. With "max", one might try to assign (nitems - 1) value. Rename the field to a more appropriate one, "items", which is also used in struct snd_ctl_elem_info, too. This patch also rewrites some code like "if (x > e->nitems - 1)" with "if (x >= e->nitems)". Not only the latter improves the readability, it also fixes a potential bug when e->items is zero.

2014-02-03ASoC: core: Add signed register volume control logicMarkus Pargmann1-7/+61
Some codecs use signed volume control representation with non standard register sizes, e.g. 6 or 7 bit signed integers. This patch adds generic signed register volume control logic to soc-core. Instead of a fixed width signed register control, this implementation uses a 'min' value and the signed bit location to translate it to an absolute volume. Using the 'sign_bit' we can calculate a correct mask for the register values and translate it back into signed integers of standard size.

2013-11-04ASoC: Add pinctrl PM to components of active DAIsNicolin Chen1-0/+33
It's quite popular that more drivers are using pinctrl PM, for example: (Documentation/devicetree/bindings/arm/primecell.txt). Just like what runtime PM does, it would deactivate and activate pin group depending on whether it's being used or not. And this pinctrl PM might be also beneficial to cpu dai drivers because they might have actual pinctrl so as to sleep their pins and wake them up as needed. To achieve this goal, this patch sets pins to the default state during resume or startup; While during suspend and shutdown, it would set pins to the sleep state. As pinctrl PM would return zero if there is no such pinctrl sleep state settings, this patch would not break current ASoC subsystem directly. [ However, there is still an exception that the patch can not handle, that is, when cpu dai driver does not have pinctrl property but another device has it. (The AUDMUX <-> SSI on Freescale i.MX6 series for example. SSI as a cpu dai doesn't contain pinctrl property while AUDMUX, an Audio Multiplexer, has it). In this case, this kind of cpu dai driver needs to find a way to obtain the pinctrl property as its own, by moving property from AUDMUX to SSI, or creating a pins link/dependency between these two devices, or using a more decent way after we figure it out. ] Signed-off-by: Nicolin Chen <b42378@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-09-17ASoC: add .of_xlate_dai_name on snd_soc_component_driverKuninori Morimoto1-0/+35
ASoC sound driver requires CPU/CODEC drivers for probing, and each CPU/CODEC has some DAI on it. Then, "dai name matching" have been used to identify CPU-CODEC DAI pair on ASoC. But, the "dai port number matching" is now required from DeviceTree. The solution of this issue is to replace the dai port number into dai name. Now, CPU/CODEC are based on struct snd_soc_component, and it can care above as common issue. This patch adds .of_xlate_dai_name callback interface on struct snd_soc_component_driver, and snd_soc_of_get_dai_name() which is using .of_xlate_dai_name. Then, #sound-dai-cells which enables DAI specifier is required on CPU/CODEC device tree properties.

Codec includes component by this patch, and component moved to upside of codec to avoid extra declaration. Codec dai will be registered via component by this patch. Current component register function is used for cpu, and it is using dai/dais functions properly to keep existing cpu dai name. And now, it will be used from codec also. But codec driver had been used dais function only even though it was single dai.
