First of all,the address of pdev->dev is assigned to mop500_card.dev,
then the function platform_set_drvdata copies the value the variable
card to pdev->dev.driver_data,but when calling snd_soc_register_card,
the function dev_set_drvdata(card->dev, card) will also do the same
copy operation,so i think that the former copy operation can be removed.

This reverts commit f1013cdeee ("ASoC: ux500: drop platform DAI
assignments"), which seems to have been based on a misunderstanding and
prevents the platform driver callbacks from being made (e.g. to
preallocate DMA memory).
The real culprit for the warnings about attempts to create duplicate
procfs entries was commit 99b04f4c40 ("ASoC: add Component level
pcm_new/pcm_free" that broke PCM creation on systems that use more than
one platform component.

This platform is completely probed by device tree nowadays, so
we need to do a bigger cleanup removing all the non-DT codepaths.
This cleanup must however go in as a fix since it fixes a
regression.
Currently when Ux500 audio is enabled, dmesg complains like
this:

This is because PCMs are created twice for the same hardware,
and this happens because both "platform" and "CPU" DAI links
are specified.
But platform/CPU is an either/or pair, not a both/and pair.
This has maybe worked in the past, but it is causing trouble
now, so let us begin the cleanups by removing the platform
assignment and silencing the boot noise, and make a proper DT
cleanup for the next kernel cycle.

does not seem to be necessary. In particular, the functions
prcmu_qos_remove_requirement and ux500_msp_i2s_cleanup_msp in the remove

Whether residue can be reported or not is not a property of the audio
controller but of the DMA controller. The FLAG_NO_RESIDUE was initially
added when the DMAengine framework had no support for describing the residue
reporting capabilities of the controller. Support for this was added quite a
while ago and recently the DMAengine framework started to complain if a
driver does not describe its capabilities and a lot of patches have been
merged that add support for this where it was missing. So it should be safe
to assume that driver on actively used platforms properly implement the DMA
capabilities API.
This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio
controller drivers to manually set the flag. If a DMA driver against
expectations does not support reporting its capabilities for now the generic
DMAengine PCM driver will now emit a warning and simply assume that residue
reporting is not supported. In the future this might be changed to aborting
with an error.

When a DMA client requests and configures a DMA channel, it requests
data_width in Bytes. The DMA40 driver then swiftly converts it over to
the necessary register bit value. Unfortunately, for any subsequent
calculations we have to shift '1' by the bit pattern (1 << data_width)
times to make any sense of it.
This patch flips the semantics on its head and only converts the value
to its respective register bit pattern when writing to registers. This
way we can use the true data_width (in Bytes) value.
