ASoC: ssm4567: replace codec to component
Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()
	.idle_bias_off = 1	->	.idle_bias_on = 0
	.ignore_pmdown_time = 0	->	.use_pmdown_time = 1
	-			->	.endianness = 1
	-			->	.non_legacy_dai_naming = 1

Bhumika Goyal a180ba45b1 ASoC: codecs: add const to snd_soc_codec_driver structures
Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.
Done using Coccinelle:

Javier Martinez Canillas 71c314d7ef ASoC: ssm4567: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Before this patch:

$ modinfo sound/soc/codecs/snd-soc-ssm4567.ko | grep alias
alias:          acpi*:INT343B:*
alias:          i2c:ssm4567

After this patch:

$ modinfo sound/soc/codecs/snd-soc-ssm4567.ko | grep alias
alias:          acpi*:INT343B:*
alias:          of:N*T*Cadi,ssm4567C*
alias:          of:N*T*Cadi,ssm4567

Kuninori Morimoto b5fce187a5 ASoC: codec duplicated callback function goes to component on ssm4567
codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

Lars-Peter Clausen 712a8038cc ASoC: ssm4567: Reset device before regcache_sync()
When the ssm4567 is powered up the driver calles regcache_sync() to restore
the register map content. regcache_sync() assumes that the device is in its
power-on reset state. Make sure that this is the case by explicitly
resetting the ssm4567 register map before calling regcache_sync() otherwise
we might end up with a incorrect register map which leads to undefined
behaviour.

One such undefined behaviour was observed when returning from system
suspend while a playback stream is active, in that case the ssm4567 was
kept muted after resume.

Lars-Peter Clausen dbe71b9d86 ASoC: ssm4567: Add sense support
The ssm4567 has sensing circuitry that can be used to monitor the current
and voltage on the speaker amplifier output has well as the VBAT input.
This data can be output over the I2S interface so it can be processed by a
DSP or similar.

This patch adds the sense capture output stream to the CODEC DAI as well as
DAPM widgets that ensure that the sensing circuitry is powered up when the
capture stream is active.

Ben Zhang a6c2a32ac8 ASoC: ssm4567: Keep TDM_BCLKS in ssm4567_set_dai_fmt
The regmap_write in ssm4567_set_dai_fmt accidentally clears the
TDM_BCLKS field which was set earlier by ssm4567_set_tdm_slot.

This patch fixes it by using regmap_update_bits with proper mask.
