To quote from section 1.3.1 of the data sheet:
The SGTL5000 has an internal reset that is deasserted
8 SYS_MCLK cycles after all power rails have been brought
up. After this time, communication can start
...
1.0us represents 8 SYS_MCLK cycles at the minimum 8.0 MHz SYS_MCLK.

One of the McASP instances in DM646x line of DMSoC only supports DIT mode.
This means that the given IP does not have support for rx and all the rx
related resources are missing, like irq and DMA request.
The driver should not fail if any or all of the RX resource is missing
when the op_mode is set to DIT mode.
Since RX is not possible in DIT mode, we can just ignore the rx resources
when the McASP is used in DIT mode.

An earlier bug fix of mine made the SND_DM365_VOICE_CODEC symbol
tristate to avoid creating an undefined reference from the
davinci-vcif.c driver to the davinci_soc_platform_register
function that may be in a module.
However, this may now lead to a different error on randconfig
kernels:
"warning: SND_DM365_VOICE_CODEC creates inconsistent choice state"
This happens because we now have a choice statement with
one bool and one tristate option, and the latter might not
support being set to 'y' because of dependencies.
This new change turns the other option into 'tristate' as well,
which avoids the problem.

The PLL introduces jitter, which in turn introduces noice if used
to clock the DAC. Thus, avoid the PLL output, and use the PLL input
to drive the DAC clock, if possible.
This is described for the PCM5142/PCM5242 chips in the answers to the
forum post "PCM5142/PCM5242 DAC clock source" at the TI E2E community
pages (1).

Using the PLL in master mode requires using an external connection
between one of the GPIO pins (configured as PLL/4 output) and the
SCK pin. It also requires the external clock to be fed to some other
GPIO pin instead of the SCK pin.
This is described for the PCM5122 chip in the answers to the forum post
"PCM5122 DAC as I2S master troubles with PLL mode" at the TI E2E
community pages (1). The clocking functionality is also much better
described in the datasheet for the chip PCM5242, which seems to be
register compatible with PCM512x and PCM514x (which both have severely
lacking datasheets).

Add helper functions to allow drivers to specify several disjoint
ranges for a variable. In particular, there is a codec (PCM512x) that
has a hole in its supported range of rates, due to PLL and divider
restrictions.
This is like snd_pcm_hw_constraint_list(), but for ranges instead of
points.

The wm97xx touchscreen driver binds itself to the snd_ac97 device that gets
registered by the CODEC driver and expects that the device has already been
reset. Before commit 6794f709b7 ("ASoC: ac97: Drop delayed device
registration") the device was only registered after the probe function of
the CODEC driver had finished running, but starting with the mentioned
commit the device is registered as soon as snd_soc_new_ac97_codec() is
called. This causes the touchscreen driver to no longer work. Modify the
CODEC drivers to use snd_soc_alloc_ac97_codec() instead of
snd_soc_new_ac97_codec() and make sure that the AC'97 device is reset before
the snd_ac97 device gets registered.

In some cases it is necessary to before additional operations after the
device has been initialized and before the device is registered. This can
for example be resetting the device.
This patch introduces a new function snd_soc_alloc_ac97_codec() which is
similar to snd_soc_new_ac97_codec() except that it does not register the
device. Any users of snd_soc_alloc_ac97_codec() are responsible for calling
device_add() manually.

When the last subscriber to a "Through" port has been removed, the
subscribed destination ports might still be active, so it would be
wrong to send "all sounds off" and "reset controller" events to them.
The proper place for such a shutdown would be the closing of the actual
MIDI port (and close_substream() in rawmidi.c already can do this).
This also fixes a deadlock when dummy_unuse() tries to send events to
its own port that is already locked because it is being freed.
