This reverts commit 75b31192

.

The original purpose of customized pcm was to config prealloc buffer size
flexibly. but, we can do the same thing by soc-generic-dmaengine-pcm.

And the generic one can generated the better config by querying DMA
capabilities from dmaengine driver rather than the Hard-Coded one.

e.g.

the customized one:

  static const struct snd_pcm_hardware snd_rockchip_hardware = {
         .info                   = SNDRV_PCM_INFO_MMAP |
                                   SNDRV_PCM_INFO_MMAP_VALID |
                                   SNDRV_PCM_INFO_PAUSE |
                                   SNDRV_PCM_INFO_RESUME |
                                   SNDRV_PCM_INFO_INTERLEAVED,
  ...

the generic one:

  ret = dma_get_slave_caps(chan, &dma_caps);
  if (ret == 0) {
          if (dma_caps.cmd_pause && dma_caps.cmd_resume)
                  hw.info |= SNDRV_PCM_INFO_PAUSE | SNDRV_PCM_INFO_RESUME;
          if (dma_caps.residue_granularity <= DMA_RESIDUE_GRANULARITY_SEGMENT)
                  hw.info |= SNDRV_PCM_INFO_BATCH;
  ...

So, let's revert back to use the generic dmaengine pcm.

The headset type detection must run to set the analogue switches
correctly for the attached headset type. Without this only headsets
with wiring matching the chip default will have a functioning mic.

commit c26a5289

 ("ASoC: cs42l42: Add support for set_jack calls")
moved the interrupt unmasking to the component set_jack() callback.
But it's not mandatory for a machine driver to register a struct
snd_soc_jack handler. Without a registered handler the type detection
would not have run and so the mic would not work on some types of
headset.

This patch restores the unmasking of TS_PLUG and TS_UNPLUG interrupts
during probe.

The driver must free the IRQ in remove() to prevent the potential race
where an IRQ starts to be handled while the driver is being removed but
devres has not yet called free_irq(). However, the driver can run without
an interrupt but devm_free_irq() will hit a WARN() if no devres-managed
interrupt was ever created.

Fix this by only attempting to create the interrupt handler if the hardware
config specified an interrupt, and failing probe() if the interrupt could
not be created. This means that in cs42l42_remove() an interrupt must have
been registered if the irq number is valid and therefore it is safe to call
devm_free_irq().

it takes around 20 milliseconds for it to power up and the midrail

If HP and ADC are both powering up in a DAPM sequence, there's no

It isn't possible to switch MCLK between 12MHz and 24MHz rate groups
on-the-fly - this can only be done when cs42l42 is powered-down.

All "normal" SCLK rates use an MCLK in the 12MHz group, so change the
configs for SCLK > 12.288 MHz to use the PLL to generate an MCLK in
the 12MHz group.

As this means MCLK_DIV is always 0 it can be removed from the pll
configuration setup.

The driver currently only supports configuring for sample rates <= 96k
and it isn't possible to setup a configuration that will support all
sample rates up to 192k.

For sample rates up to 96k MCLK is in the 12MHz group.
However, although 192k only requires an I2S clock in the 12MHz group,
the cs42l42 audio path is not natively 192k so the audio must be
resampled. But for 192k the SRC requires a 24MHz MCLK.

It is not possible to switch MCLK between 12MHz and 24MHz groups
on-the-fly. The 12MHz group supports all sample rates up to 96k.

An I2S frame always has two slots (left and right) even when sending
mono. The right channel (channel 2) of ASP TX will always have the
same bit width as the left channel and will always be on the high
phase of LRCLK.

The previous implementation always passed the field masks for both
channels to snd_soc_component_update_bits() but for mono the written value
only contained the settings for channel 1. The result was that for mono
channel 2 was set to 8-bit (which is an invalid configuration) with both
channels on the low phase of LRCLK.

When capture and playback substreams are both running at the same time,
cs42l42_pcm_hw_params() would be called for each direction. The first
call will configure the PLL. The second call must not write the PLL
configuration registers again if the first substream is already running,
as this could destabilize the PLL.

The DAI is marked symmetric sample bits and sample rate, so the two
directions will always have the same SCLK (I2S always has 2 channel slots
so the DAI does not need to require symmetric channels to guarantee the
same SCLK). However, since cs42l42_pll_config() is checking for an active
stream it may as well test that the requested SCLK is the same as the
currently active configuration.

There is a noise issue for 8kHz sample rate on slave mode.
Compared with master mode, the difference is the DACDIV
setting, after correcting the DACDIV, the noise is gone.

There is no noise issue for 48kHz sample rate, because
the default value of DACDIV is correct for 48kHz.

So wm8960_configure_clocking() should be functional for
ADC and DAC function even if it is slave mode.

In order to be compatible for old use case, just add

CBM_CFS mode (maybe not relevant). Without this fix, the result

pcm512x 0-004c: Failed to set data format: -16

And after that, no sound.

This fix is not 100% correct. The datasheet of at least the pcm5142
states that four bits (0xcc) in the I2S_1 register are "RSV"
("Reserved. Do not access.") and no hint is given as to what the
initial values are supposed to be. So, specifying defaults for
these bits is wrong. But perhaps better than a broken driver?

Merge series "ASoC: fsl: register platform component before registering cpu dai" from Shengjiu Wang <shengjiu.wang@nxp.com>:

There is no defer probe when adding platform component to
snd_soc_pcm_runtime(rtd), the code is in snd_soc_add_pcm_runtime()

snd_soc_register_card()
  -> snd_soc_bind_card()
    -> snd_soc_add_pcm_runtime()
      -> adding cpu dai
      -> adding codec dai
      -> adding platform component.

So if the platform component is not ready at that time, then the
sound card still registered successfully, but platform component
is empty, the sound card can't be used.

As there is defer probe checking for cpu dai component, then register
platform component before cpu dai to avoid such issue.

This patch set is to fix this issue for SAI, ESAI, MICFIL, SPDIF,
XCVR drivers.

When memory allocation for afe->reg_back_up fails, reg_back_up can't
be used.
Keep the suspend/resume flow but skip register backup when
afe->reg_back_up is NULL, in case illegal memory access happens.
