It's often the case that we would write or read a particular field
in register. With the current soc_component apis, reading a particular
field in register would involve first read the register and then
perform shift operations.
Ex:
to read from a field mask of 0xf0
val = snd_soc_component_read(component, reg);
field = ((val & 0xf0) >> 0x4);
This is sometimes prone to errors and code become less readable!
With this new api we could just do
field = snd_soc_component_read_field(component, reg, 0xf0);
this makes it bit simple, easy to write and less error prone!
This also applies to writing!
There are various places in kernel which provides such field interfaces
however soc_component seems to be missing this.
This patch is inspired by FIELD_GET/FIELD_PREP macros in include/linux/bitfield.h

Merge series "Add KUNIT tests for ASoC topology" from Amadeusz Sławiński<amadeuszx.slawinski@linux.intel.com>:
This series adds unit tests for ASoC topology.
First fix problems found when developing and running test cases and
then add tests implementation.
Tests themselves are quite simple and just call
snd_soc_tplg_component_load() with various parameters and check the
result. Tests themselves are described in more detail in commits
adding them.
Goal is to expand the amount of test cases in following patches.
Prerequisity for this patchset are 2 patches which have already been
sent:
https://lore.kernel.org/alsa-devel/20210114163602.911205-1-amadeuszx.slawinski@linux.intel.com/T/#t
Description on how typical test case itself works:
In order to load topology we need to have 3 things:
card, codec component & platform component.
In typical test case we register card and platform component and bind
to dummy codec. There are of course execeptions, when we want to
test behaviour of topology API when component or card is missing.
Note that this is bit different from typical scenario (in SOF and skylake
drivers) where card is registered by machine driver and component by
platform driver, as we register both when setting up test.
If you check the test case most of them have similar architecture of:
1.
/* run test */
ret = snd_soc_register_card(&kunit_comp->card);
if (ret != 0 && ret != -EPROBE_DEFER)
KUNIT_FAIL(test, "Failed to register card");
2.
ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev);
KUNIT_EXPECT_EQ(test, 0, ret);
3.
ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0);
KUNIT_EXPECT_EQ(test, 0, ret);
Ad. 1.
First we register card, which in most tests returns -EPROBE_DEFER
(from snd_soc_bind_card()), as platform component is not yet created.
I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle
this code around if needed and there is one test case which does it in
different order.
Ad. 2.
Then we initialize platform component with structure pointing at proper
probe function, which calls snd_soc_tplg_component_load() with test
parameters and checks expected result.
Ad. 3.
And then in follow up we call snd_soc_add_component() which creates
platform component for us and calls snd_soc_try_rebind_card() which
if everything is bound properly calls previously set probe function.

ASoC: cpcap: Implement set_tdm_slot for voice call support
For using cpcap for voice calls, we need to route audio directly from
the modem to cpcap for TDM (Time Division Multiplexing). The voice call
is direct data between the modem and cpcap with no CPU involvment. In
this mode, the cpcap related audio mixer controls work for the speaker
selection and volume though.
To do this, we need to implement standard snd_soc_dai_set_tdm_slot()
for cpcap. Then the modem codec driver can use snd_soc_dai_set_sysclk(),
snd_soc_dai_set_fmt(), and snd_soc_dai_set_tdm_slot() to configure a
voice call.
Let's add cpcap_voice_set_tdm_slot() for this, and cpcap_voice_call()
helper to configure the additional registers needed for voice call.
Let's also clear CPCAP_REG_VAUDIOC on init in case we have the bit for
