The output divider should align with the output sample
rate, if use ideal sample rate, there will be a lot of overload,
which would cause underrun.
The maximum divider of asrc clock is 1024, but there is no
judgement for this limitation in driver, which may cause the divider
setting not correct.
For non-ideal ratio mode, the clock rate should divide the sample
rate with no remainder, and the quotient should be less than 1024.

Commit 4ac85de997 ("ASoC: fsl: fsl_dma: remove snd_pcm_ops") removed
fsl_dma_ops but left a usage, leading to a build error for some
configs, eg. mpc85xx_defconfig:
sound/soc/fsl/fsl_dma.c: In function ‘fsl_soc_dma_probe’:
sound/soc/fsl/fsl_dma.c:905:18: error: ‘fsl_dma_ops’ undeclared (first use in this function)
dma->dai.ops = &fsl_dma_ops;
^~~~~~~~~~~
Remove the usage to fix the build.

for_each_dpcm_xx() macro is using "dpcm" as parameter (1),
but, it is also struct member (2).
#define for_each_dpcm_fe(be, stream, dpcm) \
list_for_each_entry(dpcm, &(be)->dpcm[stream]...)
^^^^(1) ^^^^(2)
Thus, it will be compile error if user not used "dpcm" as parameter
for_each_dpcm_fe(be, stream, dp)
^^
This patch fixup it.

ALSA SoC has for_each_rtdcom() which is link list for
rtd-component which is called as rtdcom. The relationship image is like below
rtdcom rtdcom rtdcom
component component component
rtd->component_list -> list -> list -> list ...
Here, the pointer get via normal link list is rtdcom,
Thus, current for_each loop is like below, and need to get
component via rtdcom->component
for_each_rtdcom(rtd, rtdcom) {
component = rtdcom->component;
...
}
but usually, user want to get pointer from for_each_xxx is component
directly, like below.
for_each_rtd_component(rtd, rtdcom, component) {
...
}
This patch expands list_for_each_entry manually, and enable to get
component directly from for_each macro.
Because of it, the macro becoming difficult to read,
but macro itself becoming useful.

dpcm_prune_paths() is checking widget at 2 parts.
(A) is for CPU, (B) is for Codec.
If we focus to (A) part, continue at (a) is for (1) loop. But,
if we focus to (B) part, continue at (b) is for (2) loop, not for (1).
This is bug.
This patch fixup this issue.

This patch implements a PCM interface for streaming hotword
phrases over SPI. Userspace can open the PCM device at anytime.
The stream is blocked when no hotword is detected. The mic
audio buffer on the DSP is a ~128KByte ring buffer that holds
~4sec of audio samples recorded from the DMIC (S16_LE, mono,
16KHz). After a hotword is detected, previous 2 seconds of audio
(containing the detected hotword) is streamed first, then live
capture continues until userspace closes the PCM stream.
When transferring, copy one period at a time then call
snd_pcm_period_elapsed(). This reduces the latency of transferring
the initial ~2sec of audio after hotword detect since audio samples
are available for userspace earlier.
