- More followups on removing legacy CODEC things and transitioning to

- 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.

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().

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.

to register a platform device, this patch also unifies related

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.

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.

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.

So this patch shortens it by using an array (fsl_ssi_regvals,
renamed from fsl_ssi_reg_val). To do that, it also introduces
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"

The machine driver links both imx-ssi (legacy non-DT driver) and
fsl_ssi (up-to-date DT based driver). So It also includes both
imx-ssi.h and fsl_ssi.h header files. This creates a limitation
for two header files -- they can't define anything with identical
names.
Since the eukrea-tlv320 machine driver now does not really need
anything being defined in the fsl_ssi header file, and it's also
going to take some time to clean up two SSI drivers, this patch
takes a quick way to remove the #include fsl_ssi.h line for now.
It can be added back once the header files are done refactoring.
The eukrea-tlv320 driver is still compiled successfully without
any erorr using imx_v6_v7_defconfig, after removing it.

When testing AC'97 capture on UDOO board (currently the only user of
fsl_ssi driver in the AC'97 mode) it become obvious that there is a massive
distortion above certain, small input signal.
This problem has been traced to silicon errata ERR003778:
"In AC97, 16-bit mode, received data is shifted by 4-bit locations" that
has "No fix scheduled".
This errata suggests a workaround of doing a 4-bit shift back in SDMA
script for this specific operation mode, however our SDMA scripts are
shared between various SoC peripherals so we can't really modify them.
There is a simple way to avoid this problem, however, that is to disallow
recording in 16-bit mode and only support it in AC'97-native 20-bit mode.
We have to use a 4-byte format for this since SSI FIFOs do not allow 3-byte
accesses (and these aren't supported by imx-sdma driver anyway).
With this change the capture distortion is gone.
We can also add this format as an additional one supported for playback,
using this opportunity to make sure that we use CPU-endian-native formats
in AC'97 mode as we already do in I2S mode.
There is no problem in using different bit widths in playback and capture
in AC'97 mode so allow this, too.

We need to make sure that only proper channel slots (in SACCST register)
are enabled at playback start time since some AC'97 CODECs (like VT1613 on
UDOO board) were observed requesting via SLOTREQ spurious ones just after
an AC'97 link is started but before the CODEC is configured by its driver.
When a bit for some channel slot is set in a SLOTREQ request then SSI sets
the relevant bit in SACCST automatically, which then 'sticks' until it is
manually unset.
The SACCST register is not writable directly, we have to use SACCDIS and
SACCEN registers to configure it instead (these aren't normal registers:
writing a '1' bit at some position in SACCEN sets the relevant bit in
SACCST; SACCDIS operates in a similar way but allows unsetting bits in
SACCST).
Theoretically, this should be necessary only for the very first playback
but since some CODECs are so untrustworthy and extra channel slots enabled
mean ruined playback let's play safe here and make sure that no extra
slots are enabled in SACCST every time a playback is started.

AC'97 register access operations (both read and write) on SSI use a one,
shared set of SSI registers for AC'97 register address and data.
This means that only one such access is possible at a time and so all these
operations need to be serialized.
Since an AC'97 register access operation in this driver takes 100us+ let's
use a mutex for this.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The set_sysclk() now is used to override the output bit clock rate.
But this is not a common way to implement a set_dai_sysclk(). And
this creates a problem when a general machine driver (simple-card
for example) tries to do set_dai_sysclk() by passing an input clock
rate for the baud clock instead of setting the bit clock rate as
fsl_ssi driver expected.
So this patch solves this problem by firstly removing set_sysclk()
since the hw_params() can calculate the bit clock rate. Secondly,
in order not to break those TDM use cases which previously might
have been using set_sysclk() to override the bit clock rate, this
patch changes the driver to calculate the bit clock rate using the
slot number and the slot width from the via set_tdm_slot().
The patch also removes an obsolete comment of the dir parameter.

The fsl_ssi fifo watermark is by default set to 2 free spaces (i.e.
activate DMA on FIFO when only 2 spaces are left.) This means the
DMA must service the fifo within 2 audio samples, which is just not
enough time for many use cases with high data rate. In many
configurations the audio channel slips (causing l/r swap in stereo
configurations, or channel slipping in multi-channel configurations).
This patch gives more breathing room and allows the SSI to operate
reliably by changing the fifio refill watermark to 8.
There is no change in behavior for older chips (with an 8-deep fifo).
Only the newer chips with a 15-deep fifo get the new behavior. I
suspect a new fifo depth setting could be optimized on the older
chips too, but I have not tested.

The i.MX51 datasheet says:
Chapter 56.1.2.4 I2S Mode
...
When I2S modes are entered (I2S master (01) or I2S slave (10)),
the following settings are recommended:
...
- TX Frame Rate should be 2 i.e. (STCCR[12:8] = 1)
- RX Frame Rate should be 2 i.e. (SRCCR[12:8] = 1)
Chapter 56.3.3.12 SSI Transmit and Receive Clock Control Registers (STCCR & SRCCR)
...
Bits 12-8 DC4-DC0
Frame Rate Divider Control. These bits are used to control the divide ratio
for the programmable frame rate dividers. The divide ratio works on the word
clock. In Normal mode, this ratio determines the word transfer rate.
In Network mode, this ratio sets the number of words per frame. The divide
ratio ranges from 1 to 32 in Normal mode and from 2 to 32 in Network mode.
In Normal mode, a divide ratio of 1 (DC=00000) provides continuous periodic
data word transfer. A bit-length frame sync must be used in this case.
Function fsl_ssi_hw_params() setup Normal mode for MONO output,
so with DC=0, SSI enters to continuous periodic data word transfer.
To fix this, setup DC for any I2S mode.
Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

If the capture is already running while playback is started, it is highly
probable (>80% in a 8 channels scenario) that samples are lost between
the DMA and TX fifo.
The reason is that SIER.TDMAE is set before STCR.TFEN0, leaving a time
window where the FIFO doesn't receive the samples written by the DMA.
This particular case happened only if capture is already enabled as
SCR.SSIEN is already set at the playback startup instant.

"
Bit clock - Used to serially clock the data bits in and out of the SSI port.
This clock is either generated internally (from SSI's sys clock) or taken
from external clock source (through the Tx/Rx clock ports).
[...]
Care should be taken to ensure that the bit clock frequency (either
internally generated by dividing the SSI's sys clock or sourced from
external device through Tx/Rx clock ports) is never greater than 1/5
of the ipg_clk (from CCM) frequency.
"
Since, in master mode, the sysclk is a multiple of bitclk, we can
easily reach a high sysclk value, whereas keeping a reasonable bitclk.
ex: 8ch x 16bit x 48kHz = 6144000, requires a 24576000 sysclk (PM=1)
yet ipg_clk/5 = 66Mhz/5 = 13.2
