d4d5a1cd29 ASoC: Updates for v4.18
This is a very big update, mainly due to a huge set of new drivers some
 of which are individually very large.  We also have a lot of fixes for
 the topology stuff, several of the users have stepped up and fixed some
 the serious issues there, and continued progress on the transition away
 from CODEC specific drivers to generic component drivers.
 
  - Many fixes for the topology code, including fixes for the half done
    v4 ABI compatibility from Guenter Roeck and other ABI fixes from
    Kirill Marinushkin.
  - Lots of cleanup for Intel platforms based on Realtek CODECs from Hans
    de Goode.
  - More followups on removing legacy CODEC things and transitioning to
    components from Morimoto-san.
  - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver.
  - A series of fixes and updates to the rather elderly Cirrus Logic SoC
    drivers from Alexander Sverdlin.
  - Qualcomm DSP support from Srinivas Kandagatla.
  - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
    MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
    RT5668 and TI TSCS454

In other places where regmap_read() is used a u32 variable is passed
to store the register read value, so do the same here as well.

regmap API already takes care of endianness, so the usage of u32 is safe.

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().

ASoC: fsl_esai: Fix divisor calculation failure at lower ratio
When the desired ratio is less than 256, the savesub (tolerance)
in the calculation would become 0. This will then fail the loop-
search immediately without reporting any errors.

But if the ratio is smaller enough, there is no need to calculate
the tolerance because PM divisor alone is enough to get the ratio.

So a simple fix could be just to set PM directly instead of going
into the loop-search.

ASoC: fsl_ssi: Move DT related code to a separate probe()
This patch cleans up probe() function by moving all Device Tree
related code into a separate function. It allows the probe() to
be Device Tree independent. This will be very useful for future
integration of imx-ssi driver which has similar functionalities
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
code.

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: Move one-time configurations to probe()
The probe() could handle some one-time configurations since
they will not be changed once being configured.

ASoC: fsl_ssi: Clean up fsl_ssi_setup_regvals()
This patch cleans fsl_ssi_setup_regvals() by following changes:
1) Moving DBG bits to the first lines.
2) Setting SSIE, RE/TE as default and cleaning it for AC97

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.

ASoC: fsl_ssi: Keep ssi->i2s_net updated
The hw_params() overwrites i2s_net settings for special cases like
mono-channel support, however, it doesn't update ssi->i2s_net as
set_dai_fmt() does.

This patch removes the local i2s_net variable and directly updates
ssi->i2s_net in the hw_params() so that the driver can simply look
up the ssi->i2s_net instead of reading the register.

ASoC: fsl_ssi: Redefine RX and TX macros
The RX and TX macros were defined implicitly and there was
a potential risk if someone changes their values.

Since they were defined to index the array ssi->regvals[2],
this patch moves these two macros to fsl_ssi.c, closer to
its owner ssi->regvals. And it also puts some comments here
to limit their value within [0, 1].
