If (quirks & QUIRK_SEC_DAI == 0) then samsung_i2s_probe() doesn't allocate
sec_dai and pri_dai->sec_dai remains Null, but samsung_i2s_remove()
performs pri_dai->sec_dai dereference in any case.
The patch removes useless reinitialization of sec_dai at
samsung_i2s_remove(), because resources are under devm control.

This driver can support more frequencies over 96KHz. There are no reasons
to limit the frequency range below 96KHz. If codecs/amps or something else
can't support higher resolution rates, the constraints would be set rates
properly because each drivers have its own limits.
I added the 'pcm_rates' field to the dai_data to be set rates by the
compatibilities. As a result, rates will be set each devices respectively.
For example of exynos5433, rates will be set from 8KHz to 192KHz.

This patch moves saving and restoring I2S registers to runtime PM

When support for audio power domain is enabled and the domain is being

implemented on top of runtime PM operations with generic

The driver was checking for non-NULL address of struct's members:
- s3c_audio_pdata->type (union),
- s3c_audio_pdata->type.i2s (embedded struct).
This is pointless as these will be always non-NULL. The 's3c_audio_pdata'
is always initialized in static memory so it will be zeroed.
Additionally the 'type' member was an union with only one member.
It is safe to reorganize the structures to get rid of useless union and
checks for addresses to fix the coccinelle warning:

ASoC Samsung sub-drivers tried to get access to their DMA engine
controllers as a last step in driver probe. If a DMA engine was not
available yet, samsung_asoc_dma_platform_register() function ended in
-EPROBE_DEFER, but the driver already registered its component to ASoC
core. This patch moves samsung_asoc_dma_platform_register() call before
registering any components, to the common place, where driver was gathering
all needed resources.
In case of Samsung Exynos i2s driver the issue was even worse. The driver
managed already to register its secondary DAI platform device before
even getting the DMA engine access. That together with -EPROBE_DEFER error
code from samsung_i2s_probe() immediately triggered another round of
deferred probe retry and in turn endless loop of driver probing.

As we are now passing the filter data as pointers to the drivers,
we can take the final step and also pass the filter function the
same way. I'm keeping this change separate, as there it's less
obvious that this is a net win.
Upsides of this are:
- The ASoC drivers are completely independent from the DMA engine
implementation, which simplifies the Kconfig logic and in theory
allows the same sound drivers to be built in a kernel that supports
different kinds of dmaengine drivers.
- Consistency with other subsystems and drivers
On the other hand, we have a few downsides:
- The s3c24xx-dma driver now needs to be built-in for the ac97 platform
device to be instantiated on s3c2440.
- samsung_dmaengine_pcm_config cannot be marked 'const' any more
because the filter function pointer needs to be set at runtime.
This is safe as long we don't have multiple different DMA engines
in thet same system at runtime, but is nonetheless ugly.

ARM64 allmodconfig produces a bunch of warnings when building the
samsung ASoC code:
sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data':
sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
capture_data->filter_data = (void *)capture->channel;
We could easily shut up the warning by adding an intermediate cast,
but there is a bigger underlying problem: The use of IORESOURCE_DMA
to pass data from platform code to device drivers is dubious to start
with, as what we really want is a pointer that can be passed into
a filter function.
Note that on s3c64xx, the pl08x DMA data is already a pointer, but
gets cast to resource_size_t so we can pass it as a resource, and it
then gets converted back to a pointer. In contrast, the data we pass
for s3c24xx is an index into a device specific table, and we artificially
convert that into a pointer for the filter function.

The intention is also to fix the CDCLK gating issue reported by

the Odroid X2/U3, which doesn't configure the CDCLK clock in

now resolved by using clk API, i.e. having the codec enabling/

The clk_prepare_enable() call on the "iis" clock is moved to happen earlier
in the DAI platform device driver's probe() callback, so the I2S registers
can be safely accessed through the clk API, after the clk supplier is
registered in the platform device probe().
After this patch the "iis" clock is kept enabled since the (primary) I2S
platform device probe() and until the platform device driver remove() call.
This is similar to gating the clock in the snd_soc_dai probe() and remove()
callbacks.
Normally, in addition to that we should mark the device as PM runtime active,
so if runtime PM is enabled it can idle the device by turning off the clock.
Correcting this issue is left for a separate patch series, as we need to
ensure the BUSCLK clock is always enabled when required.

inadvertently changed the name of one of the properties used by the
driver (Fabio Estevam).
- Fix a regression in the ACPI backlight driver introduced by a
recent fix that missed one special case that had to be taken into
account (Aaron Lu).
- Drop the level of some new kernel messages from the ACPI core
introduced by a recent commit to KERN_DEBUG which they should have
used from the start and drop some other unuseful KERN_ERR messages
printed by ACPI (Rafael J Wysocki).
- Revert an incorrect commit modifying the cpupower tool (Prarit
Bhargava).
- Fix two regressions introduced by recent commits in the OPP library
and clean up some existing minor issues in that code (Viresh
Kumar).
- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
tree (or drop it where that can be done) in order to make it
possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
Hansson, Ludovic Desroches).
There will be one more "CONFIG_PM_RUNTIME removal" batch after this
one, because some new uses of it have been introduced during the
current merge window, but that should be sufficient to finally get
rid of it.
- Make the ACPI EC driver more robust against race conditions related
to GPE handler installation failures (Lv Zheng).
- Prevent the ACPI device PM core code from attempting to disable
GPEs that it has not enabled which confuses ACPICA and makes it
report errors unnecessarily (Rafael J Wysocki).
- Add a "force" command line switch to the intel_pstate driver to
make it possible to override the blacklisting of some systems in
that driver if needed (Ethan Zhao).
- Improve intel_pstate code documentation and add a MAINTAINERS entry
for it (Kristen Carlson Accardi).
- Make the ACPI fan driver create cooling device interfaces witn
names that reflect the IDs of the ACPI device objects they are
associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").
That's necessary for user space thermal management tools to be able
to connect the fans with the parts of the system they are supposed
to be cooling properly. From Srinivas Pandruvada"

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under sound/.

The changes in commit a5a56871f8 (ASoC: samsung: add support for exynos7
I2S controller) introduce a new variant_regs structure in the driver data
which is now mandatory for accessing registers. Unfortunately this is only
hooked up for DT platforms so non-DT platforms like my primary development
platform for audio are broken by this change and crash on boot.
Since the only non-DT user of these device is s3c64xx fix this by making
the standard samsung-i2s device be of type I2Sv3 and add a new I2Sv4 name
to the platform data section, currently using the I2Sv5 information which
should be about right.

In the i2s_set_sysclk() callback we are currently clearing all bits
of the IISMOD register in i2s_set_sysclk. It's due to an incorrect
mask used for the AND operation which is introduced in commit
a5a56871f8 (ASoC: samsung:
add support for exynos7 I2S controller) and also adds the missing
break statement.

Exynos7 I2S controller has no internal dma, supports more
no. of root clock sampling frequencies and has more no.of Rx
fifos to support 7.1CH recording in TDM mode. Due to more no.
of root clock frequency values some of the bit offsets got
shifted up by one. Also I2S1 on previous Samsung platforms
uses v3 dai type but on Exynos7 it is upgraded to v5 with
slightly modified register offsets for supporting more no.of
RFS values. Due to the above changes, the driver has to be
modified to handle all versions of I2S controller. For this
I introduced a new structure to hold modified bit offsets and
masks which is passed as dai data.

Internal DMA is available only on some of Samsung platforms.
So added a quirk for the same and made it optional.
