2018-02-26ASoC: Revert "ASoC: soc-generic-dmaengine-pcm: Fix error handling"Fabio Estevam
This reverts commit f91b1e73ccde71d4bc69ae10d475196df38844ab. As explained by Lars-Peter Clausen: "This creates a resource leak. dmaengine_pcm_request_chan_of() requests bothtransmit and receive channels. It might return with an error if one of them fails, but the other one succeeded. In this case we need to call dmaengine_pcm_release_chan() to free the requested channel" So revert the commit.

2018-02-26ALSA: hda - Fix pincfg at resume on Lenovo T470 dockTakashi Iwai
We've added a quirk to enable the recent Lenovo dock support, where it overwrites the pin configs of NID 0x17 and 19, not only updating the pin config cache. It works right after the boot, but the problem is that the pin configs are occasionally cleared when the machine goes to PM. Meanwhile the quirk writes the pin configs only at the pre-probe, so this won't be applied any longer. For addressing that issue, this patch moves the code to overwrite the pin configs into HDA_FIXUP_ACT_INIT section so that it's always applied at both probe and resume time.

2018-02-24ALSA: hda: Add a power_save blacklistHans de Goede
On some boards setting power_save to a non 0 value leads to clicking / popping sounds when ever we enter/leave powersaving mode. Ideally we would figure out how to avoid these sounds, but that is not always feasible. This commit adds a blacklist for devices where powersaving is known to cause problems and disables it on these devices. Note I tried to put this blacklist in userspace first: https://github.com/systemd/systemd/pull/8128 But the systemd maintainers rightfully pointed out that it would be impossible to then later remove entries once we actually find a way to make power-saving work on listed boards without issues. Having this list in the kernel will allow removal of the blacklist entry in the same commit which fixes the clicks / plops. The blacklist only applies to the default power_save module-option value, if a user explicitly sets the module-option then the blacklist is not used.

2018-02-22ALSA: x86: hdmi: Add single_port option for compatible behaviorTakashi Iwai
The recent support for the multiple PCM devices allowed user to use multiple HDMI/DP outputs, but at the same time, the PCM stream assignment has been changed, too. Due to that, the former PCM#0 (there was only one stream in the past) is likely assigned to a different one (e.g. PCM#2), and it ends up with the regression when user sticks with the fixed configuration using the device#0. Although the multiple monitor support shouldn't matter when user deploys the backend like PulseAudio that checks the jack detection state, the behavior change isn't always acceptable for some users. As a mitigation, this patch introduces an option to switch the behavior back to the old-good-days: when the new option, single_port=1, is passed, the driver creates only a single PCM device, and it's assigned to the first connected one, like the earlier versions did. The option is turned off as default still to support the multiple monitors.

This patch cleans up probe() function by moving all Device Tree related code into a separate function. It allows the probe() to be Device Tree independent. This will be very useful for future integration of imx-ssi driver which has similar functionalities while exists only because it supports non-DT cases. This patch also moves symmetric_channels of AC97 from the probe to the structure snd_soc_dai_driver for simplification. Additionally, since PowerPC and AC97 use the same pdev pointer to register a platform device, this patch also unifies related code.

This patch cleans the _fsl_ssi_set_dai_fmt() in following ways: * Removing *dev pointer in the parameters as it's included in the *ssi pointer of struct fsl_ssi. * Using regmap_update_bits() instead of regmap_read() with masking the value manually. * Moving baudclk check to the switch-case routine to skip the I2S master check.

2018-02-21ASoC: fsl_ssi: Setup AC97 in fsl_ssi_hw_init()Nicolin Chen
AC97 configures most of registers earlier to start a communication with CODECs in order to successfully initialize CODEC. Currently, _fsl_ssi_set_dai_fmt() and fsl_ssi_setup_ac97() are called to get all SSI registers properly set. Since now the driver has a fsl_ssi_hw_init() to handle all register initial settings, this patch moves those register settings of AC97 to the fsl_ssi_hw_init() as well. Meanwhile it applies _fsl_ssi_set_dai_fmt() call to AC97 only since other formats would be configured via normal set_dai_fmt() directly. This patch also adds fsl_ssi_hw_clean() to cleanup control bits for AC97 in the platform remote() function.

2018-02-21ASoC: fsl_ssi: Clean up helper functions of trigger()Nicolin Chen
The trigger() calls fsl_ssi_tx_config() and fsl_ssi_rx_config(), and both of them jump to fsl_ssi_config(). And fsl_ssi_config() later calls another fsl_ssi_rxtx_config(). However, the whole routine, especially fsl_ssi_config() function, is too complicated because of the folowing reasons: 1) It has to handle the concern of the opposite stream. 2) It has to handle cases of offline configurations support. 3) It has to handle enable and disable operations while they're mostly different. Since the enable and disable routines have more differences than TX and RX rountines, this patch simplifies these helper functions with the following changes: - Changing to two helper functions of enable and disable instead of TX and RX. - Removing fsl_ssi_rxtx_config() by separately integrating it to two newly introduced enable & disable functions.

Meanwhile, FIFO clear could be applied to all use cases, not confined to AC97. So this patch also moves FIFO clear in the trigger() to fsl_ssi_config() and removes the AC97 check.

2018-02-21ASoC: fsl_ssi: Rename fsl_ssi_disable_val macroNicolin Chen
The define of fsl_ssi_disable_val is not so clear as it mixes two steps of calculations together. And those parameter names are also a bit long to read. Since it just tries to exclude the shared bits from the regvals of current stream while the opposite stream is active, it's better to use something like ssi_excl_shared_bits. This patch also bisects fsl_ssi_disable_val into two macros of two corresponding steps and then shortens its parameter names. It also updates callers in the fsl_ssi_config() accordingly.

With in ACP, There are three I2S controllers can be configured. (I2S SP ,I2S MICSP and I2S BT).These controllers can support both playback/capture scenarios. Default enabled i2s controller instance is i2s sp instance. Renamed stream names and bytescount params as i2ssp. These changes required to distinguish with other I2S controller instance pcm substreams and bytescount params.

2018-02-19ASoC: dmic: Add optional wakeup delayMatthias Kaehlcke
On some systems a delay is needed after switching on the clocks, to allow the output to stabilize and avoid a popping noise at the beginning of the recording. Add the optional device tree property 'wakeup-delay-ms' and apply the specified delay after enabling the mic. A blocking delay can't be applied in dmic_daiops_trigger() since the function is called in atomic context. Instead use a DAPM event handler to set the enable GPIO and apply the delay in the handler.
