The dev->name of CODEC might not be identical to its codec_dai_name,

According to the datasheet 'pm', 'psr' and 'div2' should never be all 0.
Since commit 541b03ad6c ("ASoC: fsl_ssi: Fix the incorrect limitation of
the bit clock rate") this can happen, because for some bitclock rates
'pm' = 0 seems to be a valid choice but does not work due to hardware
restrictions. This results into a bad hardware behaviour (slow audio for
example). Feature tested on a i.MX25.

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.

The dapm field of the snd_soc_codec struct will eventually be removed
(replaced with the DAPM context from the component embedded inside the
CODEC). Replace its usage with the card's DAPM context. The idea is that
DAPM is hierarchical and with the card at the root it is possible to access
widgets from other contexts through the card context.

Finally there are fixes for drivers that improperly compared struct clk

drivers have done this for a long time, this did not cause a problem
until we started generating unique struct clk pointers for every
consumer. A new function, clk_is_match was introduced to get these

Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers. That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get(). This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place. The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.
That said, the struct clk pointer comparing in the code doesn't work any
more. Call helper function clk_is_match() instead to fix the problem.

According to i.MX6 Series Reference Manual, the formula to calculate
the sys clock is
sysclk rate = bclk rate * (div2 + 1) * (7 * psr + 1) * (pm + 1) * 2
Commit aafa85e71a ("ASoC: fsl_ssi: Add DAI master mode support for
SSI on i.MX series") added the divisor calculation which relies on
the clk_round_rate(). However, at that time, clk_round_rate() didn't
provide closest clock rates for some cases because it might not use
a correct rounding policy. So using the original formula (pm + 1) for
PM divisor was not able to give us a desired clock rate. And then we
used (pm + 2) to do the trick.
However, the clk-divider driver has been refined a lot since commit
b11d282dbe ("clk: divider: fix rate calculation for fractional rates")
Now using (pm + 2) trick would result an incorrect clock rate.
So this patch fixes the problem by removing the useless trick.

According to i.MX Reference Manual, the bit-clock frequency generated
by SSI must be never greater than 1/5 of the peripheral clock frequency.
This peripheral clock, however, is not baudclk but the IPG clock (i.e.
ssi_private->clk in the fsl_ssi driver).
So this patch just simply fixes the incorrect limitation applied to
the bit clock (baudclk) rate.
