* ASoC: wm_adsp: Add basic debugfs entriesRichard Fitzgerald2015-06-112-4/+202
| | | | | | | | This patch adds some debugfs nodes to get information about the currently running firmware. Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: wm_adsp: create ALSA controls from wm_adsp driverRichard Fitzgerald2015-06-114-26/+24
| | | | | | | | | Now that we have a codec_probe stage initialization in the wm_adsp driver, we can make the wm_adsp driver create its own ALSA controls instead of having that responsibility pushed to every codec driver.

* ASoC: wm_adsp: Add codec_probe and codec_remove stubsRichard Fitzgerald2015-06-114-1/+31
| | | | | | | | | | | | | | Currently the only init function in wm_adsp is called by the codec driver early in its probe before the codec has been registered with SOC. This patch adds stubs for the codec_probe and codec_remove stages and calls them from WM5102 and WM5110 codec drivers. This allows us to hang anything that needs setup during the codec probe stage off these functions without further modification of the codec drivers.

* ASoC: wm_adsp: Move DVFS control into codec driverRichard Fitzgerald2015-06-024-83/+54
| | | | | | | | | | | | | In theory the ADSP driver should not need to know anything about the codec it is part of. But the WM5102 needs DVFS control based on ADSP clocking speed. This was being handled by bundling part of the knowledge of this into the ADSP driver. This change moves this handling out of the ADSP driver and into the WM5102 driver.

* ASoC: arizona: Export functions to control subsystem DVFSRichard Fitzgerald2015-06-024-7/+157
| | | | | | | | | | | | | | | | | | | | | | | | | The WM5102 and WM8997 codecs have an internal dynamic clock booster. When this booster is active, the DCVDD voltage must be increased. If all the currently active audio paths can run with the root SYSCLK we can disable the booster, allowing us to turn down DCVDD voltage to save power. Previously this was being done by having the booster enable bit set as a side-effect of the LDO1 regulator driver, which is unexpected behaviour of a regulator and not compatible with using an external regulator. [Originally this was documented as a feature of the internal LDO -- broonie] This patch exports functions to handle the booster enable and DCVDD voltage, with each relevant subsystem flagging whether it can currently run without the booster. Note that these subsystems are stateless and none of them are nestable, so there's no need for reference counting, we only need a simple boolean for each subsystem of whether their current condition could require the booster or will allow us to turn the codec down to lower operating power.

| * ASoC: wm_adsp: Warn that firmware file format 0 is depreciatedCharles Keepax2015-04-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | There are very few version 0 firmwares in the wild and at some point in the future it would be nice to remove support for them from the driver, as they require several work arounds to be present to create controls properly. This patch adds a depreciated warning if someone is using this file format. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
| * ASoC: wm_adsp: Add support for rev 2 firmware file formatCharles Keepax2015-04-271-18/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Version 2 of the firmware file format includes length fields for the various strings associated with control creation, to reduce file size. However this does increase the parsing complexity slightly. This patch adds support for the revision of the file format. This patch also adds a new naming scheme for controls created from rev 2 firmware files. This version of the file format is commonly used to add multiple controls per algorithm per memory region and the old control naming scheme would cause multiple controls to have the same name in this case.. Note that the naming scheme for older firmware versions is left intact to ensure backwards compatibility.

This patch updates the processing to handle this version of the file format. Note that whilst this version of the format adds support for specifying a name for the control through the firmware file this has not been used and to keep compatibility with existing deployments no changes to the firmware control naming are made by this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | Physically reading and writing controls to/from the DSP are handled by two low level functions (wm_coeff_{write|read}_control, these currently take in a snd_kcontrol pointer but immediately pull out a wm_coeff_ctl pointer from the private data. These functions don't handle the kcontrols at all they just shuttle data to and from the chip and all the call sites have a wm_coeff_ctl pointer available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have wm_adsp_region, wm_adsp_alg_region, and wmfw_region, the variables for which are all frequently called region, this can get quite confusing when reviewing the code especially given some functions are quite long. Consistently use mem for wm_adsp_regions, alg_region for wm_adsp_alg_region and region for wmfw_region. Additionally, we use a mix of adsp and dsp for pointers to the wm_adsp structure standardise this on dsp. Finally, we use algs to refer to the number of algorithms quite frequently, change this to the more descriptive n_algs.

| | | | | | | | | | | | | | | | | | | | | | The vast majority of the wm_adsp_setup_algs function is case statements for ADSP1 or ADSP2, this patch splits this out into two separate functions wm_adsp1_setup_algs and wm_adsp2_setup_algs. The small amount of shared code between them is factored out into an extra helper function. This makes the code a lot cleaner.

* | ASoC: dapm: Add new widgets to the end of the widget listLars-Peter Clausen2015-05-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently new widgets are appended to the beginning of the cards widget list. This has the effect that widgets that are created while iterating over the widget list in snd_soc_dapm_new_widgets() (like e.g. the auto-disable widgets) are not covered during that invocation of the function. If no further invocations of snd_soc_dapm_new_widgets() happen these widgets will not be fully initialized and e.g. no debugfs entries are created for them. By adding new widgets to the end of the widget list we make sure that widgets that are created in snd_soc_dapm_new_widgets() will still be handled during the same snd_soc_dapm_new_widgets() invocation and are always fully initialized.

This GPIO pin updates the USB cable states. 2. Rename the filename of extcon core driver and add missing locking mechanism - Rename the previous extcon-class driver.c as extcon.c because '-class' postfix is not necessary word. - extcon core driver (extcon.c) used the raw_notifier_chain. It must be protected by locking mechanism to avoid the list changing while extcon_update_state() is executed. 3. Fix minor issue of extcon drviers - Fix cable name by using the capital letter instead of small letter on extcon-max77693.c driver. - Clean-up code of extcon-arizona.c to detect headphone cable. - Fix the wrong return type and variable type on extcon-max77843.c. - Fix the checkpatch warning of all extcon drivers.

This patch simply adds a lower-bounds of 1.

This can be problematic when using output clocks from the wm8804 for other devices. The snd_soc_codec_set_pll API defines that a clock should be available once the call returns, however, with all the clocking controlled in set_bias_level this is not currently the case. This patch enables pm_runtime for the wm8804, enabling both the regulators and the oscillator when the chip resumes, and enabling the PLL in the snd_soc_codec_set_pll call. Naturally the enabling the PLL will also cause the chip to resume. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
| | | | | * | | ASoC: wm8804: Add DAPM widgets for SPDIF/AIFSapthagiri Baratam2015-04-081-57/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change converts the driver to use DAPM to control the power for the various blocks on the chip. As part of this change the existing controls "TX Playback Switch" (controlled power for the SPDIF TX block) and "AIF Playback Switch" (controlled power for the AIF block) are both removed, as they are now redundant since the power state of those blocks is controlled automatically by DAPM. There are several benefits of this change, the most important of which is this change adds support for powering down the SPDIF RX block. The RX block will automatically assume control of the PLL on the chip when it is receiving a signal, so leaving this enabled all the time as was currently done in the driver can be problematic. An incoming SPDIF signal that is not being used can completely destroy the clocking for an in use TX signal. But this change ensures that the RX block will only be powered when the user intends to be receiving data, thus avoiding this issue. Additional benefits include the chip being simpler to operate as the power no longer needs to be manually controlled between use-cases and a small power saving (although it is acknowledged that this is likely unimportant in the typical use-cases for this chip).

Firstly, fail probe if we can't register the regulator notifiers as this will cause the cache to never be synchronised which will result in odd behaviour if the regulators are controllable. Secondly, we don't need to call regulator_bulk_disable if the enable fails, because the regulator core will handle this clean up for us. Finally, we need to disable the regulators if snd_soc_register_codecs fails. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
