Tidy up the samsung_i2s_get_driver_data() function by using
IS_ENABLE() instead of #ifdef and add missing braces for
the 'else' part. Also ensure we are not dereferencing NULL
'match' pointer.

Subject: ASoC: samsung: i2s: Request memory region in driver probe()

The memory mapped registers region is common for both DAIs so request
it in the I2S platform device driver's probe for the platform device
corresponding to the primary DAI, rather than in the ASoC DAI's probe
callback. While at it switch to devm_ioremap_resource(). This also
drops the hard coded (0x100) register region size in the driver.

Subject: ASoC: samsung: i2s: Move clk_get() to platform driver probe()

Acquire the I2S interface clock in driver probe() callback
as it's a per-device not a per-DAI clock. While at it switch
to the resource managed clk_get().

Date: Wed, 14 Jan 2015 19:42:32 +0100
Subject: ASoC: samsung: i2s: Move clk enable to the platform driver probe()

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.

Subject: ASoC: samsung: i2s: Add spinlock in place of local_irq_* calls

It seems this driver hasn't been updated for SMP, as local_irq_save/
local_irq_restore don't provide proper protection of read/modify/write
of the device's registers on such systems. Introduce a spinlock
serializing access to the register region, it will be helpful later
when I2SMOD, I2SPSR registers are made also accessible through the
clk API.

Subject: ASoC: samsung: odroidx2: Handle I2S CDCLK clock conditionally

In order to support old DTs we check the codec device node if it
contains "clocks" property and only if it doesn't (which indicates
an old DT) we proceed with enabling the CDCLK clock by means of
the set_sysclk() callback.  For new DTs which use the common clock
bindings for CDCLK that clock is supposed to be handled outside
the sound machine driver.

Subject: ASoC: samsung: i2s: Add clock provider for the I2S internal clocks

This patch adds clock provider (currently only for DT platforms) for
the CODECLKO (CDCLK) gate, RCLKSRC mux and RCLK pre-scaler divider
divider clock. Those all tree clock are only available in the IIS
Multi Audio Interface (I2S0), the regular IIS Bus Interface has only
CDCLK gate clock.

The motivation behind this patch is to expose the I2S internal clocks
which are currently controlled through set_sysclk() through the clk
API, so dedicated sound machine driver per each board can be avoided.

The intention is also to fix the CDCLK gating issue reported by
Daniel Drake:
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-September/081753.html

This patch also reverts commit b97c60abf9a561f86ae71bd741add02673cc1
("ASoC: samsung-i2s: Maintain CDCLK settings across i2s_{shutdown/
startup}") The problem that commit attempted to solve only affects
the Odroid X2/U3, which doesn't configure the CDCLK clock in
struct snd_soc_dai_ops hw_params callback and the issue should be
now resolved by using clk API, i.e. having the codec enabling/
disabling the CDCLK clock as required.

Subject: ASoC: jive: Automatically disconnect non-connected pins

All DAPM input and output pins of the wm8750 are either used in the card's
DAPM routing table or are marked as not connected.

Set the fully_routed flag of the card instead of manually marking the unused
inputs and outputs as not connected. This makes the code a bit shorter and
cleaner.

Subject: ASoC: samsung: Replace depends on REGMAP_I2C with depends on I2C

regmap is a library function that gets selected by drivers that need it. No
driver modules should depend on it, since this can create dependency loops.

E.g. if machine driver depends on REGMAP_I2C and selects the CODEC driver
and the CODEC driver selects REGMAP_I2C, then the machine driver selects by
extension one of its dependencies.

The proper way to handle this is for machine drivers to depend on the same
dependencies as the CODEC driver they select. In this case it is I2C.

Subject: ASoC: samsung: Remove goni or aquila with the WM8994

Commit 28c8331d386a ("ARM: S5PV210: Remove support for board files")
removed the Kconfig symbols MACH_GONI and MACH_AQUILA. As a result the
dependencies of SND_SOC_GONI_AQUILA_WM8994 can never be met. So remove
the unbuildable "SoC I2S Audio support for AQUILA/GONI - WM8994".
