The generic snd_dmaengine_pcm is able to retrieve all the needed
information from the attached dmaengine and is in fact able to
provide much more accurate flags to userspace, like the SDMA engine
being only able to operate in batch mode.

To avoid any future inconsistencies between the dmaengine and the
pcm_config, rip out the fixed config and rely on the core to fill
in the right flags derived from the dmaengine information.

Arnd Bergmann 245c5c7b08 ASoC: fix ES8328_I2C/SPI dependencies
The two front-ends to the codec can now be selected individually, but fail to
build when the bus support is missing:

sound/built-in.o: In function `es8328_spi_probe':
es8328-spi.c:(.text+0x125854): undefined reference to `__devm_regmap_init_spi'
sound/built-in.o: In function `es8328_spi_driver_init':
es8328-spi.c:(.init.text+0x3589): undefined reference to `__spi_register_driver'

Related to this, the added dependency on SND_SOC_ES8328 breaks:

warning: (SND_SOC_ALL_CODECS) selects SND_SOC_ES8328_I2C which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_ES8328 && I2C)

This adds the respective Kconfig dependencies and changes SND_SOC_ES8328 to a hidden
symbol that is selected implicitly by the two more specific options, as we do for
some other codecs. We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the
same step to avoid a recursive dependency.

Caleb Crome 4ee437fbf6 ASoC: fsl_ssi: set fifo watermark to more reliable value
The fsl_ssi fifo watermark is by default set to 2 free spaces (i.e.
activate DMA on FIFO when only 2 spaces are left.)  This means the
DMA must service the fifo within 2 audio samples, which is just not
enough time  for many use cases with high data rate.  In many
configurations the audio channel slips (causing l/r swap in stereo
configurations, or channel slipping in multi-channel configurations).

This patch gives more breathing room and allows the SSI to operate
reliably by changing the fifio refill watermark to 8.

There is no change in behavior for older chips (with an 8-deep fifo).
Only the newer chips with a 15-deep fifo get the new behavior. I
suspect a new fifo depth setting could be optimized on the older
chips too, but I have not tested.

Marek Vasut bfcf928d76 ASoC: fsl_ssi: use flat regmap cache
Same as commit ce492b3b8f
Subject: drm/fsl-dcu: use flat regmap cache

Using flat regmap cache instead of RB-tree to avoid the following
lockdep warning on driver load:
WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128
DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))

The RB-tree regmap cache needs to allocate new space on first
writes. However, allocations in an atomic context (e.g. when a
spinlock is held) are not allowed. The function regmap_write
calls map->lock, which acquires a spinlock in the fast_io case.
Since the driver uses MMIO, the regmap bus of type regmap_mmio
is being used which has fast_io set to true.

Marek Vasut 35ddb15757 ASoC: fsl_spdif: use flat regmap cache
Same as commit ce492b3b8f
Subject: drm/fsl-dcu: use flat regmap cache

Using flat regmap cache instead of RB-tree to avoid the following
lockdep warning on driver load:
WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128
DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))

The RB-tree regmap cache needs to allocate new space on first
writes. However, allocations in an atomic context (e.g. when a
spinlock is held) are not allowed. The function regmap_write
calls map->lock, which acquires a spinlock in the fast_io case.
Since the driver uses MMIO, the regmap bus of type regmap_mmio
is being used which has fast_io set to true.

Julia Lawall 115c725488 ASoC: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops.  The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.

The semantic patch that makes this change is as follows:
