ASoC: Use of_property_read_bool() for boolean properties
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().

ASoC: fsl_ssi: Rename AC'97 streams to avoid collisions with AC'97 CODEC
The SSI driver calls the AC'97 playback and transmit streams "AC97 Playback"
and "AC97 Capture" respectively. This is the same name used by the generic
AC'97 CODEC driver in ASoC, creating confusion for the Freescale ASoC card
when it attempts to use these widgets in routing. Add a "CPU" in the name
like the regular DAIs registered by the driver to disambiguate.

ASoC: fsl: Migrate to new style legacy DAI naming flag
Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
These drivers appear to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

ASoC: fsl_ssi: Fix bclk calculation for mono channel
For mono channel, SSI will switch to Normal mode.

In Normal mode and Network mode, the Word Length Control bits
control the word length divider in clock generator, which is
different with I2S Master mode (the word length is fixed to
32bit), it should be the value of params_width(hw_params).

The condition "slots == 2" is not good for I2S Master mode,
because for Network mode and Normal mode, the slots can also
be 2. Then we need to use (ssi->i2s_net & SSI_SCR_I2S_MODE_MASK)
to check if it is I2S Master mode.

So we refine the formula for mono channel, otherwise there
will be sound issue for S24_LE.

ASoC: fsl_ssi: Fix clock control issue in master mode
The test case is

aplay -Dhw:0 -d 30 -f S16_LE -r 48000 -c 2 test.wav

There will be error after end of arecord:
aplay: pcm_write:2051: write error: Input/output error

Capture and Playback work in parallel in master mode, one
substream stops, the other substream is impacted, the
reason is that clock is disabled wrongly.

The clock's reference count is not increased when second
substream starts, the hw_param() function returns in the
beginning because first substream is enabled, then in end
of first substream, the hw_free() disables the clock.

This patch is to move the clock enablement to the place
before checking of the device enablement in hw_param().

ASoC: fsl_ssi: Fix mode setting when changing channel number
This is a partial revert (in a cleaner way) of commit ebf08ae3bc
("ASoC: fsl_ssi: Keep ssi->i2s_net updated") to fix a regression
at test cases when switching between mono and stereo audio.

The problem is that ssi->i2s_net is initialized in set_dai_fmt()
only, while this set_dai_fmt() is only called during the dai-link
probe(). The original patch assumed set_dai_fmt() would be called
during every playback instance, so it failed at the overriding use
cases.

This patch adds the local variable i2s_net back to let regular use
cases still follow the mode settings from the set_dai_fmt().

Meanwhile, the original commit of keeping ssi->i2s_net updated was
to make set_tdm_slot() clean by checking the ssi->i2s_net directly
instead of reading SCR register. However, the change itself is not
necessary (or even harmful) because the set_tdm_slot() might fail
to check the slot number for Normal-Mode-None-Net settings while
mono audio cases still need 2 slots. So this patch can also fix it.
And it adds an extra line of comments to declare ssi->i2s_net does
not reflect the register value but merely the initial setting from
the set_dai_fmt().

while exists only because it supports non-DT cases.

This patch also moves symmetric_channels of AC97 from the probe
to the structure snd_soc_dai_driver for simplification.

Additionally, since PowerPC and AC97 use the same pdev pointer
to register a platform device, this patch also unifies related

ASoC: fsl_ssi: Clean up _fsl_ssi_set_dai_fmt()
The _fsl_ssi_set_dai_fmt() is a helper function being called from
fsl_ssi_set_dai_fmt() as an ASoC operation and fsl_ssi_hw_init()
mainly for AC97 format initialization.

This patch cleans the _fsl_ssi_set_dai_fmt() in following ways:
* Removing *dev pointer in the parameters as it's included in the
  *ssi pointer of struct fsl_ssi.
* Using regmap_update_bits() instead of regmap_read() with masking
  the value manually.
* Moving baudclk check to the switch-case routine to skip the I2S
  master check. And moving SxCCR.DC settings after baudclk check.
* Adding format settings for SND_SOC_DAIFMT_AC97 like others.

ASoC: fsl_ssi: Setup AC97 in fsl_ssi_hw_init()
AC97 configures most of registers earlier to start a communication
with CODECs in order to successfully initialize CODEC. Currently,
_fsl_ssi_set_dai_fmt() and fsl_ssi_setup_ac97() are called to get
all SSI registers properly set.

Since now the driver has a fsl_ssi_hw_init() to handle all register
initial settings, this patch moves those register settings of AC97
to the fsl_ssi_hw_init() as well.

Meanwhile it applies _fsl_ssi_set_dai_fmt() call to AC97 only since
other formats would be configured via normal set_dai_fmt() directly.

This patch also adds fsl_ssi_hw_clean() to cleanup control bits for
AC97 in the platform remote() function.

ASoC: fsl_ssi: Add DAIFMT define for AC97
The _fsl_ssi_set_dai_fmt() bypasses an undefined format for AC97
mode. However, it's not really necessary if AC97 has its complete
format defined.

So this patch adds a DAIFMT macro of complete format including a
clock direction and polarity.

ASoC: fsl_ssi: Clean up helper functions of trigger()
The trigger() calls fsl_ssi_tx_config() and fsl_ssi_rx_config(),
and both of them jump to fsl_ssi_config(). And fsl_ssi_config()
later calls another fsl_ssi_rxtx_config().

However, the whole routine, especially fsl_ssi_config() function,
is too complicated because of the folowing reasons:
1) It has to handle the concern of the opposite stream.
2) It has to handle cases of offline configurations support.
3) It has to handle enable and disable operations while they're
   mostly different.

Since the enable and disable routines have more differences than
TX and RX rountines, this patch simplifies these helper functions
with the following changes:
- Changing to two helper functions of enable and disable instead
  of TX and RX.
- Removing fsl_ssi_rxtx_config() by separately integrating it to
  two newly introduced enable & disable functions.

ASoC: fsl_ssi: Clear FIFO directly in fsl_ssi_config()
The FIFO clear helper function is just one line of code now.
So it could be cleaned up by removing it and calling regmap
directly.

Meanwhile, FIFO clear could be applied to all use cases, not
confined to AC97. So this patch also moves FIFO clear in the
trigger() to fsl_ssi_config() and removes the AC97 check.

Note that SOR register is safe from offline_config HW limit.

ASoC: fsl_ssi: Rename fsl_ssi_disable_val macro
The define of fsl_ssi_disable_val is not so clear as it mixes two
steps of calculations together. And those parameter names are also
a bit long to read.

Since it just tries to exclude the shared bits from the regvals of
current stream while the opposite stream is active, it's better to
use something like ssi_excl_shared_bits.

This patch also bisects fsl_ssi_disable_val into two macros of two
corresponding steps and then shortens its parameter names. It also
updates callers in the fsl_ssi_config() accordingly.

ASoC: fsl_ssi: Maintain a mask of active streams
Checking TE and RE bits in SCR register doesn't work for AC97 mode
which enables SSIEN, TE and RE in the fsl_ssi_setup_ac97() that's
called during probe().

So when running into the trigger(), it will always get the result
of both TE and RE being enabled already, even if actually there is
no active stream.

This patch fixes this issue by adding a variable to log the active
streams manually.

This patch removes the local i2s_net variable and directly updates

up the ssi->i2s_net instead of reading the register.

The name fsl_ssi_rxtx_reg_val is too long to read comfortably.
So this patch shortens it by using an array (fsl_ssi_regvals,

two macros (TX and RX) to replace the wrapper structure. This
will also help further cleanups.

Meanwhile, it unifies all local variable with the name "vals"
to get rid of the name "reg" -- could be confusing with "regs"
in the private struct for regmap.
