driver fixes for new regressions since v3.19. Second are fixes to the
common clock divider type caused by recent changes to how we round clock
rates. This affects many clock drivers that use this common code.
Finally there are fixes for drivers that improperly compared struct clk
pointers (drivers must not deref these pointers). While some of these
drivers have done this for a long time, this did not cause a problem
until we started generating unique struct clk pointers for every
consumer. A new function, clk_is_match was introduced to get these
drivers working again and they are fixed up to no longer deref the
pointers themselves.

Pull clock framework fixes from Michael Turquette:
"The clk fixes for 4.0-rc4 comprise three themes.
First are the usual driver fixes for new regressions since v3.19.
Second are fixes to the common clock divider type caused by recent
changes to how we round clock rates. This affects many clock drivers
that use this common code.
Finally there are fixes for drivers that improperly compared struct
clk pointers (drivers must not deref these pointers). While some of
these drivers have done this for a long time, this did not cause a
problem until we started generating unique struct clk pointers for
every consumer. A new function, clk_is_match was introduced to get
these drivers working again and they are fixed up to no longer deref

Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers. That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get(). This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place. The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.
That said, the struct clk pointer comparing in the code doesn't work any
more. Call helper function clk_is_match() instead to fix the problem.

According to i.MX6 Series Reference Manual, the formula to calculate
the sys clock is
sysclk rate = bclk rate * (div2 + 1) * (7 * psr + 1) * (pm + 1) * 2
Commit aafa85e71a ("ASoC: fsl_ssi: Add DAI master mode support for
SSI on i.MX series") added the divisor calculation which relies on
the clk_round_rate(). However, at that time, clk_round_rate() didn't
provide closest clock rates for some cases because it might not use
a correct rounding policy. So using the original formula (pm + 1) for
PM divisor was not able to give us a desired clock rate. And then we
used (pm + 2) to do the trick.
However, the clk-divider driver has been refined a lot since commit
b11d282dbe ("clk: divider: fix rate calculation for fractional rates")
Now using (pm + 2) trick would result an incorrect clock rate.
So this patch fixes the problem by removing the useless trick.

According to i.MX Reference Manual, the bit-clock frequency generated
by SSI must be never greater than 1/5 of the peripheral clock frequency.
This peripheral clock, however, is not baudclk but the IPG clock (i.e.
ssi_private->clk in the fsl_ssi driver).
So this patch just simply fixes the incorrect limitation applied to
the bit clock (baudclk) rate.

...
In order to avoid such problem, fill the card owner field as suggested by
Lars-Peter Clausen:
"But looking at the source it seems that this is a core feature of ALSA and at
least for the card module itself it will do the ref-counting when a stream is
started/stopped. And we even support setting the owner of a card in ASoC.
It's just that pretty much no ASoC card driver bothers to set the owner field
in the snd_soc_card struct. So this particular problem can be fixed by updating
the imx-wm8962 driver to set the owner field."
By doing as suggested, we no longer see the crash when attempting to unload the
snd_soc_imx_wm8962 module while playback is active:

ASoC: Updates for v3.19
Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter. Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.
- Conversion of AC'97 drivers to use regmap, bringing us closer to the
removal of the ASoC level I/O code.

The cause of problem and solution are well explained by Lars-Peter:
"The driver creates the mapping by calling irq_of_parse_and_map(), so it also
has to dispose the mapping. But the easy way out is to simply use
platform_get_irq() instead of irq_of_parse_map(). In this case the mapping is
not managed by the device but by the of core, so the device has not to dispose
the mapping."
Tested on a imx6q-sabresd board.

ESAI may need to use fixed slot width to comply with external
CODEC. So this set_tdm_slot() call will allow the ESAI driver
to override its default dynamic slot width policy.
Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com>
Signed-off-by: Mark Brown <broonie@kernel.org>
The driver previously used 32-bit fixed slot width as default.
In result, ESAI might use 32-bit length to capture 16-bit width
audio slot from CODEC side when ESAI is running as DAI slave.
So this patch just removes the default slot_width so as to use
dynamic slot width. If there comes a specific situation that
needs a fixed width, the machine driver shall set slot_width
via set_tdm_slot() so as to let the ESAI driver replace the
dynamic width policy with the fixed value.

Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.
While we are at it also change the type from int to bool.
The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>
@@
identifier drv;

The mpc5200_dma overwrites the private_data field of the CODEC's AC'97
device with the DMA drivers private data, but never actually reads it again.
Given that the private_data field is supposed to be owned by the AC'97
driver, overwriting it may cause undefined behavior. This patch removes the
code that overwrites the field from the driver.

When cpu-dai is the DAI Master (CBM_CFx), it may need some configurations,

By looking at 2744 line, we can get that it's because regcache_rbtree_write()

The 'big-endian-data' property is originally used to indicate whether the
LSB firstly or MSB firstly will be transmitted to the CODEC or received
from the CODEC, and there has nothing relation to the memory data.
Generally, if the audio data in big endian format, which will be using the
bytes reversion, Here this can only be used to bits reversion.
So using the 'lsb-first' instead of 'big-endian-data' can make the code
to be readable easier and more easy to understand what this property is
used to do.
This property used for configuring whether the LSB or the MSB is transmitted

There is one design rule according to SAI's reference manual:
If the transmitter bit clock and frame sync are to be used by both transmitter
and receiver, the transmitter must be configured for asynchronous operation
and the receiver for synchronous operation.
And SYNC of TCR2 is a 2-width control bit:
00 Asynchronous mode.
01 Synchronous with receiver.
10 Synchronous with another SAI transmitter.
11 Synchronous with another SAI receiver.
So the driver should have set SYNC bit of TCR2 to 0x0, and meanwhile set SYNC

The Freescale Generic ASoC Sound Card is a general ASoC DAI Link driver that
can be used, ideally, for all Freescale CPU DAI drivers and external CODECs.
The idea of this generic sound card is a bit like ASoC Simple Card. However,
for Freescale SoCs (especially those released in recent years), most of them
have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
this is a specific feature that might be painstakingly controlled and merged
into the Simple Card driver.
So having this driver will allow all Freescale SoC users to benefit from the
simplification to support a new card and the capability of wide sample rates
support through ASRC.
The driver is initially designed for sound card using I2S or PCM DAI formats.
However, it's also possible to merge those non-I2S/PCM type sound cards, such
as S/PDIF audio and HDMI audio, into this card as long as the merge will not
break the original function and as long as there is something redundant that
can be abstracted along with I2S type sound cards.
As an initial version, it only supports three cards that I can test:
imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC
imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver
imx-audio-wm8962, just like the old imx-wm8962.c driver
The driver is also compatible with the old Device Tree bindings of WM8962 and
SGTL5000. So we may consider to remove those two drivers after this driver is
totally enabled. (It needs to be added into defconfig)

2, Mask IRQ of Tx/Rx to enable its interrupt.
3, Enable DMA request of Tx/Rx.
As this flow would enable DMA request later than TERE, the Tx FIFO
would be easily emptied into underrun while Rx FIFO would be easily
stuffed into overrun due to the delayed DMA transfering.
This issue happened merely occational before the patch 'ASoC: fsl_sai:

I received a report this morning from one of the Novena developers that
the behaviour of the iMX6 ASoC codec driver (using imx-pcm-dma.c) was
sub-optimal under high system load.
While there are issues relating to system load remaining, upon reviewing
the ASoC imx-pcm-dma.c driver, it was noticed that it not using the
residue support, because SDMA doesn't support it. This has the effect
that SDMA has to make multiple calls into the ASoC and ALSA code, one
for each period.
Since ALSA's snd_pcm_elapsed() does not need to be called multiple times
and it is entirely sufficient to call it once to update ALSA with the
current buffer position via the pointer method, we can do better here.
We can also avoid stopping the DMA entirely, just like real cyclic DMA
implementations behave. While this means that we replay some old samples,
this is a nicer behaviour than having audio stop and restart.
The changes to achieve this are relatively minor - imx-sdma.c can track
where the DMA is to the nearest descriptor boundary - it does this
already when deciding how many callbacks to issue. In doing this,
buf_tail always points at the descriptor which will complete next.
The residue is defined by the bytes remaining to the end of the buffer,
when the buffer is viewed as a single block of memory [start...end].
So, when we start out, there's a full buffer worth of residue, and this
counts down as we approach the end of the buffer, eventually becoming
zero at the end, before returning to the full buffer worth when we
wrap back to the start.
Moving the walking of the descriptors into the interrupt handler means
that we can update the BD_DONE flag at interrupt time, thus avoiding
a delayed tasklet stopping the cyclic DMA.
This means that the residue can be calculated from (total descriptors -
buf_tail) * descriptor size. This is what the change below does. We
update imx-pcm-dma.c to remove the NO_RESIDUE flag since we now provide
the residue.

SND_SOC_IMX_PCM_FIQ for two drivers when building for i.MX.
This has turned out too aggressive, as FIQ is only available
for i.mx2 through i.mx5, but not i.mx6 or vybrid.
Further, two more drivers have become user-selectable in the
meantime, and they both depend on DMA for the imx platform
as well.
This changes the selection of FIQ to depend on the TZIC or
AVIC interrupt controllers that actually export the imx
specific FIQ interfaces, and adds the missing select statements
for SAI and ESAI.

The baudclock may be used and set by different streams.
Allow only the first stream to set the bitclock rate. Other streams have
to try to get to the correct rate without modifying the bitclock rate
using the SSI internal clock modifiers.
The variable baudclk_streams is introduced to keep track of the active
streams that are using the baudclock. This way we know if the baudclock
may be set and whether we may enable/disable the clock.
baudclock enable/disable is moved to hw_params()/hw_free(). This way we can
keep track of the baudclock in those two functions and avoid a running
clock while it is not used. As hw_params()/hw_free() may be called
multiple times for the same stream, we have to use baudclk_streams
variable to know whether we may enable/disable the clock.

The fsl_ssi driver uses the .set_sysclk callback to configure the
bitclock for master mode. This is unnecessary since the bitclock
is known in hw_params. This patch configures the bitclock from .hw_params.
.set_dai_sysclk now sets a bitclock frequency which is preferred over
the default calculated bitclock frequency.

Since commit 204dec93ea "ASoC: fsl: Allow to select individual common
options", it is possible to enable SND_SOC_FSL_SSI and SND_SOC_FSL_SPDIF
manually, either as loadable modules or built-in. This unfortunately
leads to a link error if one or both of them are built-in, while
the imx-pcm-dma framework is a loadable module:
sound/built-in.o: In function `fsl_ssi_probe':
:(.text+0x51fb8): undefined reference to `imx_pcm_dma_init'
sound/built-in.o: In function `fsl_spdif_probe':
:(.text+0x52e20): undefined reference to `imx_pcm_dma_init'
This changes Kconfig to prevent this case by using 'select' to turn
on the imx-pcm-dma code from both drivers. For consistency, we also
turn on the imx-pcm-fiq code, which is an alternative to the dma
implementation.
Note that imx-pcm-fiq is platform dependent, so we must not enable
that unless we are building a kernel for i.MX. Note also the
"if SND_IMX_SOC != n" syntax as opposed to the normal "if SND_IMX_SOC".
This is needed to avoid turning on the options as 'm' if 'SND_IMX_SOC'
is a module.

Building ARM randconfig got into a situation where CONFIG_INPUT
is turned off and SND_SOC_ALL_CODECS is turned on, which failed
for two codecs trying to use the input subsystem. Some other
drivers also select one of these codecs and consequently need an
explicit dependency added.
Appending to the dependency list seems the easiest way out,
since this is not a practical limitation. If anyone really
needs to build these codecs for a kernel with no input support,
a more sophisticated solution can be implemented.

fsl_ssi_set_dai_fmt() manages most of the register setup routines now.
fsl_ssi_setup() makes the same as fsl_ssi_set_dai_fmt() but it relies on
DT properties.
In most cases the settings of fsl_ssi_setup() are already overwritten by
fsl_ssi_set_dai_fmt() when it is called by the soc-core when a sound
card is added. As these settings depend on the combination of codec and
cpu DAI, this should really be done by sound cards.
This patch removes fsl_ssi_setup() and adds the missing register setups
to fsl_ssi_set_dai_fmt(). It also removes all calls to fsl_ssi_setup().

The SAI mainly has the following clocks:
bus clock
control and configure registers and to generate synchronous
interrupts and DMA requests.
mclk1, mclk2, mclk3
to generate the bit clock when the receiver or transmitter is
configured for an internally generated bit clock.
So this patch adds these clocks and their clock controls to the driver.
[ To concern the old DTB cases, I've added a bit of extra code to make
the driver compatible with them. And by marking clock NULL if failed
to get, the clk_prepare() or clk_get_rate() would easily return 0
so no further path should be broken. -- by Nicolin ]

The current trigger() has two crucial problems:
1) The DMA request enabling operations (FSL_SAI_CSR_FRDE) for Tx and Rx are
now totally exclusive: It would fail to run simultaneous Tx-Rx cases.
2) The TERE disabling operation depends on an incorrect condition -- active
reference count that only gets increased in snd_pcm_open() and decreased
in snd_pcm_close(): The TERE would never get cleared.
So this patch overwrites the trigger function by following these rules:
A) We continue to support tx-async-while-rx-sync-to-tx case alone, which's
originally limited by this fsl_sai driver, but we make the code easy to
modify for the further support of the opposite case.
B) We enable both TE and RE for PLAYBACK stream or CAPTURE stream but only
enabling the DMA request bit (FSL_SAI_CSR_FRDE) of the current direction
due to the requirement of SAI -- For tx-async-while-rx-sync-to-tx case,
the receiver is enabled only when both the transmitter and receiver are
enabled.

a) aplay test.wav -d5
b) arecord -r44100 -c2 -fS16_LE test.wav -d5

The BCP bit in TCR4/RCR4 register rules as followings:
0 Bit clock is active high with drive outputs on rising edge
and sample inputs on falling edge.
1 Bit clock is active low with drive outputs on falling edge
and sample inputs on rising edge.
For all formats currently supported in the fsl_sai driver, they're exactly
sending data on the falling edge and sampling on the rising edge.
However, the driver clears this BCP bit for all of them which results click
noise when working with SGTL5000 and big noise with WM8962.
