Renesas sound has SSI/SRC/DVC/MIX/ADG modules, and these have original
register mapping. Thus this driver is using regmap field, and each module
is using it based on each module ID.
Sometimes, each module needs other module to controlling. but current each
function is using just "mod" as parameter name. This is confusable.
For example, if SSI0 and SRC2 are connected, and if SRC module function
has bug of module access, and if it needs to control connected SSI,
SRC function will access to SSI2 (It should access to SSI0, but it uses
SRC's ID 2). This is easy to happen in current driver style.
To avoid this kind of confusable trouble, this patch adds module confirm
macro for debug purpose.

- Newer Tegra chip supports
- More quirks for Dell headsets, Alienware (with CA0132), etc.
- A couple of DRM ELD helper API functions
* ASoC
- Support for loading ASoC topology maps from firmware, intended to be

- Lots of refactoring to avoid direct access to snd_soc_codec where

Pull clkdev updates from Russell King:
"This series addresses some breakage in clkdev caused by a previous
patch set from the clk tree which introduced per-user clk structures.
This basically renamed the existing 'struct clk' to 'struct clk_hw',
and introduced a new 'struct clk'.
This change will break anyone using clk_add_alias() with the common
clk code enabled. Thankfully, the intersection of users of
clk_add_alias() and those using the common clk code is practically
zero, but this is something which should be fixed to keep the code
sane.
The problem is that clk_add_alias() does this:
r = clk_get(...);
l = clkdev_alloc(r, ...);
clk_put(...);
which causes the alias to store a pointer to 'r', which has been
freed.
The original patch set tried to work around this problem incorrectly -
at clk_get() time, it tried to convert the struct clk to a struct
clk_hw, and then creating a new struct clk from that. Clearly, if the
original struct clk has been freed, then we have a use-after-free bug.
We have other places in the tree which do something similar, so this
series also addresses those locations too.
This series addresses this problem by converting clkdev to store and
use the clk_hw pointer. This allows clk_get() to only have to create
it's per-user struct clk from the clk_hw. We can also get to the
desired clk_hw at clk_add_alias() or clk lookup creation time, when
the struct clk is "alive".
We also perform some cleanups of the code:
- replacing looped calls to clkdev_add() with clkdev_add_table()
- replacing open-coded lookup allocation (which should have been
using clkdev_alloc()) and subsequent clkdev_add() with
clkdev_create()
- replacing open-coded clk_add_alias() with clk_add_alias()"

:(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'
This could be fixed either by adding a static inline wrapper

implements the second approach, which seems appropriate
because the driver in fact has a hard dependency.

This patch implements DPCM feature on DT as Renesas specific sound card.

1. removed unused feature from simple-card
2. removed driver named prefix from DT property
3. CPU will be FE, CODEC will be BE with snd-soc-dummy
4. it supports sampling rate convert via .be_hw_params_fixup

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as
Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC).
And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine.
But, in result of DMA ML discussion, 2nd DMAC was concluded that it is
not a general purpose DMAC (2nd DMAC is for Device to Device inside
sound system). Additionally, current DMAEngine can't support Device to
Device, and we don't have correct DT bindings for it at this point.
So the easiest solution for it is that move it from DMAEngine to rsnd
driver.
dma-names on DT was implemented as no difference between 1st / 2nd
DMAC's, since rsnd had assumed that both DMACs are implemented as
DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented
as non DMAEngine, and it doesn't need dma-names anymore. So, this
dma-names rule is no longer needed.
And additionally, dma-names was assumed that it has all
(= SSI/SSIU/SRC/DVC) nodes under sound node.
In upstream code, no SoC/platform is supporting DMA for rsnd driver yet.
This means there is no compatible issue if this patch changes
dma-names's rule of DT.
This patch assumes dma-names for 1st DMAC are tx/rx base, and listed
in each SSI/SRC/DVC subnode
ex)
rcar_sound,dvc {
dvc0: dvc@0 {
dmas = <&audma0 0xbc>;
dma-names = "tx";
};
...
rcar_sound,src {

dmas = <&audma0 0x85>, <&audma1 0x9a>;

Renesas sound driver had been assumed that Audio DMAC /
Audio DMAC peri peri are implemented by DMAEngine. But, result of DMA
ML discussion, it was concluded that it is not a general purpose DMAC.
And it should be moved from current DMAEngine to rsnd driver.
So, Audio DMAC peri peri become non DMAEngine.
OTOH, ALSA SoC has soc-generic-dmaengine-pcm implementation. but it
seems difficult to use this generic implementation on rsnd driver at
this point, since it needs to fallback to PIO mode if DMA can't use.
and additionally it needs 2 DMAC (= Audio DMAC / Audio DMAC peri peri).
These are not "generic" feature.
Of course I will try to use this generic dmaengine in the future somehow,
but just use current style at this point until it can formally use 2 DMACs.
This patch adds new dma.c and moves current dma code to dma.c from core.c.

R-Car sound can use SSI/SRC/DVC modules, and these are controlled as
rsnd_mod in rsnd driver. These rsnd_mod has each own function as
callback. Basically these callback function has pair like probe/remove,
start/stop, etc. And, these functions are called by order to each stage
like below.
1. src->probe
2. ssi->probe
3. dvc->probe
4. src->start
5. ssi->start
6. dvc->start
7. src->stop
8. ssi->stop
9. dvc->stop
10. src->remove
11. ssi->remove
12. dvc->remove
But, current rsnd driver doesn't care about its status which indicates
which function is called.
For example, if 5) returns error, 6) is not called. In such case,
9) should not be called. This patch care about each modules status.

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.
