Now the debugfs files dais/platforms/codecs have a size limit PAGE_SIZE and
the user can not see the whole contents of dai_list/platform_list/codec_list
when they are larger than this limit.
This patch uses seq_file instead to make sure dais/platforms/codecs show the
full contents of dai_list/platform_list/codec_list.

If bcm2835 is configured as bitclock master calling hw_params()
after prepare() fails with EBUSY. This also makes it impossible to
use bcm2835 in full duplex mode.
The error is caused by the split clock setup: clk_set_rate
is called in hw_params, clk_prepare_enable in prepare. As hw_params
doesn't check if the clock was already enabled clk_set_rate
fails with EBUSY.
Fix this by moving clock startup from prepare to hw_params and
let hw_params properly deal with an already set up or enabled
clock.

The E1 has two headphone jacks, one of which can be set as a microphone
input. In the default mode, it uses the built-in microphone as an input.
By sending a special command, the second headphone jack is instead used
as an input.
This might work with the E3 as well, but I don't have one of those to
test it.

The second assignment to res is identical to the previous assignment

In current ALSA SoC, Codec only has .read/.write callback.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

The tasklet is used to defer the execution of snd_pcm_period_elapsed() to
the softirq context. Using the HRTIMER_MODE_SOFT mode invokes the timer
callback in softirq context as well which renders the tasklet useless.

The commit ffcd28d88e4f ("ALSA: hda - Select INPUT for Realtek
HD-audio codec") introduced the reverse-selection of CONFIG_INPUT for
Realtek codec in order to avoid the mess with dependency between
built-in and modules. Later on, we obtained IS_REACHABLE() macro
exactly for this kind of problems, and now we can remove th INPUT
selection in Kconfig and put IS_REACHABLE(INPUT) to the appropriate
places in the code, so that the driver doesn't need to select other
subsystem forcibly.

The loop timeout doesn't work because it's a post op and ends with "tmo"
set to -1. I changed it from a post-op to a pre-op and I changed the
initial the starting value from 5 to 6 so we still iterate 5 times. I
left the other as it was because it's a large number.

The SNDRV_SEQ_IOCTL_SET_QUEUE_TEMPO ioctl sets the tempo and the ppq
in a single call, while the current implementation updates each value
one by one. This is a bit racy, and also suboptimal from the
performance POV, as each call does re-acquire the lock and invokes
the update of ALSA timer resolution.
This patch reorganizes the code slightly so that we change both the
tempo and the ppq in a shot. The skew value can be put into the same
lock, but this is rather a rarely used feature and completely
independent from the temp/ppq (it's evaluated only in the interrupt),
so it's left as it was.

The capture interface does not work, and the playback interface
actually supports only 48kHz unlike what is advertised (44.1, 32, 22,
16, 8).
The only unknown here is if there are other devices that use the same
product ID, but given that this ID is currently unknown, I would assume
it is specially allocated for the nura headset.

ASoC: Updates for v4.16
Some more updates for v4.16, the big things here are the ST DFSDM driver
and the IIO patches required to support that and even more in the
neverending series of code quality improvements for x86, including
Pierre's work to improve the Kconfig. The unused SN95031 driver and
associated board support are also removed, they haven't been buildable
for a considerable time without anyone noticing.
