2009-10-06ASoC: Add virtual enumeration support for DAPM muxesMark Brown1-0/+10
Sometimes it is desirable to have a mux which does not reflect any direct register configuration but which will instead only have an effect implicitly (for example, as a result of changing which parts of the device are powered up). Provide a virtual mux for this purpose. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-10-01ASoC: add support for multiple cards/codecs in debugfsPeter Ujfalusi1-0/+1
In order to support multiple codecs on the same system in the debugfs the directory hierarchy need to be changed by adding directory per codec under the asoc direcorty: debugfs/asoc/{dev_name(socdev->dev)}-{codec->name}/codec_reg /dapm_pop_time /dapm/{widgets} With the original implementation only the debugfs files are only created for the first codec, other codecs loaded later would fail to create the debugfs files (since they are already exist). Furthermore in this situation any of the codecs has been removed, would cause the debugfs entries to disappear, regardless if the codec, which created them are still loaded (the one which loaded first).

2009-09-13ASoC: Provide API for reordering channelsBarry Song1-0/+7
The patch adds an interface to set the relationship between audio channel number and slot number. The interface should be really useful because audio channel n doesn't always use slot n in all platforms. And for some devices, the relationship even can change with sound mode switch in 2.1,3.1,4.1,5.1,6.1,7.1 etc. Signed-off-by: Barry Song <21cnbao@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-09-08ASoC: Allow per-route connectedness checks for suppliesMark Brown1-0/+7
Some chips with complex internal supply (particularly clocking) arragements may have multiple options for some of the supply connections. Since these don't affect user-visible audio routing the expectation would be that they would be managed automatically by one of the drivers. Support these users by allowing routes to have a connected function which is queried before the connectedness of the path is checked as normal. Currently this is only done for supplies, other widgets could be supported but are not currently since the expectation for them is that audio routing will be under the control of userspace.

2009-09-05ASoC: Add source argument to PLL configurationMark Brown1-3/+3
More and more devices feature PLLs and FLLs with the ability to select between multiple input clocks. In order to better support these devices a new argument, source, has been added to the set_pll() configuration API. Using set_clkdiv() is often difficult due to the need to stop the PLL/FLL before any reconfiguration can be done. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-08-21ASoC: Add DAPM widget power decision debugfs filesMark Brown2-0/+2
Currently when built with DEBUG DAPM will dump information about the power state decisions it is taking for each widget to dmesg. This isn't an ideal way of getting the information - it requires a kernel build to turn it on and off and for large hub CODECs the volume of information is so large as to be illegible. When the output goes to the console it can also cause a noticable impact on performance simply to print it out. Improve the situation by adding a dapm directory to our debugfs tree containing a file per widget with the same information in it. This still requires a decision to build with debugfs support but is easier to navigate and much less intrusive. In addition to the previously displayed information active streams are also shown in these files. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-08-18ASoC: Add input and output AIF widgetsMark Brown1-0/+8
Currently DAPM interfaces with the audio streams to and from the processor at the DAC and ADC widgets. As the digital capabilities of parts increases this is becoming a less and less able to meet the needs of parts. To meet the needs of these devices create new widgets interfacing with the TDM bus but not integrated into any other functionality. Audio can then be routed to and from these widgets using existing routing widgets. A slot number is provided in the definition but this is currently not used yet. This is intended to support devices which can use more than one TDM slot on a single interface. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Extend set_tdm_slot to allow the user to arbitrarily set the frame width and active TX/RX slots. Updates magician.c and wm9081.c for the new set_tdm_slot(). wm9081.c still doesn't handle the slot_width override. While being there, correct an incorrect use of SlotsPerFrm(7) use in bitmask on pxa-ssp.c (SSCR0_SlotsPerFrm(x) is (((x) - 1) << 24)) ).

2009-07-05ASoC: Begin to factor out register cache I/O functionsMark Brown1-0/+2
A lot of CODECs share the same register data formats and therefore replicate the code to manage access to and caching of the register map. In order to reduce code duplication centralised versions of this code will be introduced with drivers able to configure the use of the common code by calling the new snd_soc_codec_set_cache_io() API call during startup. As an initial user the 7 bit address/9 bit data format used by many Wolfson devices is supported for write only CODECs and the drivers with straightforward register cache implementations are converted to use it.

2009-06-16ASoC: UDA1380: refactor device registrationPhilipp Zabel1-0/+22
This patch mostly follows commit 5998102b9095fdb7c67755812038612afea315c5 "ASoC: Refactor WM8731 device registration" to make UDA1380 use standard device instantiation. Similarly, the I2C device registration temporarily moves into the magician machine driver before it will find its final resting place in the board file. At the same time, platform specific configuration is moved to platform data and common power/reset GPIO handling moves into the codec driver.

2009-06-13ASoC: Add stub suspend and resume calls for ASoC subdevicesMark Brown1-0/+5
Now that ASoC subdevices can be regular devices they can have normal suspend and resume calls from their buses. However, suspending them individually is not desirable since this can lead to problems such as pops and clicks from devices being suspended with their signals being amplified or clocks being stopped suddenly. This will be resolved by having the normal device model suspend and resume calls call into ASoC which will suspend the entire card while any of its components are suspended. At present this is not yet implemented but in order to aid the transition of drivers to the standard device model this patch adds API calls for the notifications.

Rather than managing the bias level of the system based on if there is an active audio stream manage it based on there being an active DAPM widget.

2009-05-18ASoC: Split DAPM power checks from sequencing of power changesMark Brown2-0/+5
DAPM has always applied any changes to the power state of widgets as soon as it has determined that they are required. Instead of doing this store all the changes that are required on lists of widgets to power up and down, then iterate over those lists and apply the changes. This changes the sequence in which changes are implemented, doing all power downs before power ups and always using the up/down sequences (previously they were only used when changes were due to DAC/ADC power events). The error handling is also changed so that we continue attempting to power widgets if some changes fail. The main benefit of this is to allow future changes to do optimisations over the whole power sequence and to reduce the number of walks of the widget graph required to check the power status of widgets.
