Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.
Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

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.

Move the auto disable DSP function from the widget event "DAPM Pre" to
the set_bias_level() function to avoid the unexpected behavior. While the
SPI was recording using the DAI "rt5514-dsp-cpu-dai", the event "DAPM Pre"
would be manipulated even the DAPM widgets were not connected, and it also
would power off the DSP that cause the DSP buffered data lost. So the auto
disable DSP function should move to the set_bias_level() function to make
sure that it is only manipulated by the DAPM widgets are connected.

The rt5514 can get confused and incorrectly detect a start bit if the
SCL/SDA lines happen to both go low and then high again. This
situation has been seen to happen at reboot time and is also
theoretically possible during suspend/resume if the rt5514 keeps power
but we shut down the i2c connection.
When this happens the rt5514 is confused about the state of the i2c
bus and won't recognize its own address. That will lead to the rt5514
incorrectly NAKing the first transfer.
A single i2c transfer to any address should be enough to get the
rt5514 out of this funky state.
It is currently believed that this problem should be fixed in the
rt5514 driver itself because it seems that the i2c controller in the
rt5514 is easily confused. Most i2c devices wouldn't detect a start
bit in this case.

In rt5514_i2c_probe() if the regmap_read(RT5514_VENDOR_ID2) fails then
"val" may be left as uninitialized. Current code relies on "val" not
being RT5514_DEVICE_ID, but that's potentially unsafe.
Let's check for errors from regmap_read() and also explicitly init the
value do we're not passing a possibly uninitialized int to printk.

The device has multiple control interfaces, I2C and SPI. The I2C interface
mainly controls the register settings of codec. The SPI interface is in
order to provide the high speed transmission of data. For example, high

for loading the firmware of DSP and retrieving the voice data from DSP
after the system is waked up by specific voice.

This is the initial codec driver for rt5514. The codec includes a low power
DSP for voice wake up. The register address is incremental by 4 in the DSP
memory map. In order to recover the codec settings in the codec mode and
manipulate the DSP mode for voice wake up, we use the multi-level register
map. One is for ALSA API in codec mode that can be recovered by cache
before recording. Another is for DSP related settings that can be accessed
with 32bit address of the DSP in the application of voice wake up.
