95e9ee92e2 ASoC: Intel: Fix audio crash due to negative address offset
There were occasional ADSP crash during reboot testing:

[   11.883364] BUG: unable to handle kernel paging request at ffffc90121700000
[   11.883380] IP: [<ffffffffc024d8bc>] sst_module_insert_fixed_block+0x24f/0x26d [snd_soc_sst_dsp]
[   11.883397] PGD 7800b067 PUD 0
[   11.883405] Oops: 0002 [#1] SMP
[   11.886418] gsmi: Log Shutdown Reason 0x03

The virtual address, ffffc90121700000, was out of range. The virtual
address is calculated by adding LPE base address with an offset:

sst_memcpy32(dsp->addr.lpe + data->offset, data->data, data->size);

The offset is calculated in sst_byt_parse_module, by subtraction of
two virtual addresses dsp->addr.fw_ext and dsp->addr.lpe:

block_data.offset = block->ram_offset + (dsp->addr.fw_ext - dsp->addr.lpe);

These virtual addresses are assigned by kernel from ioremap:

sst->addr.lpe = ioremap(pdata->lpe_base, pdata->lpe_size);
sst->addr.fw_ext = ioremap(pdata->fw_base, pdata->fw_size);

In current driver code, offset is defined as unsigned int32:

struct sst_module_data {
...
	u32 offset;		/* offset in FW file */
};

Most of the time kernel assigned virtual addresses with addr.fw_ext
greater than addr.lpe. But sometimes it was the other way round.

Fix the problem by declaring offset as signed int32_t.

7897ab78f6 ASoC: Intel: some incorrect sizeof() usages
The intent was to say "sizeof(*pos)" and not "sizeof(pos)".

The sizeof(*pos) is 8 bytes so the bug won't show up on 64 bit systems.
The sizeof(*dx) is 172 bytes so that will be a bugfix.

f6272ff8a5 ASoC: Add snd_soc_kcontrol_platform() helper function
For platform controls snd_kcontrol_chip() currently returns a pointer to the
platform that registered the control. With the upcoming consolidation of
platform and CODEC controls this will change. Prepare for this by introducing
the snd_soc_kcontrol_platform() helper function that will hide the
implementation details of how the platform for a control can be obtained. This
will allow us to change this easily in the future.

The patch also updates all platforms to use this new helper function.

43b956349d ASoC: mfld_machine: Convert to table based DAPM and control setup
Use table based setup to register the controls and DAPM widgets and routes.
This on one hand makes the code a bit cleaner and on the other hand
the board level DAPM elements get registered in the card's DAPM context rather
than in the CODEC's DAPM context.

The mfld_machine driver is a bit special in that it directly writes to one of
the CODEC registers from one of the control handlers. Previous to this patch it
was able to get a pointer to the CODEC from the control, since the control was
registered with the CODEC. This won't be possible anymore once the control is
registered with the card. Since there are already global variables in the driver
accessed in the same function the patch adds a global variable that holds a
pointer to the CODEC and uses that.

234bf1f0f0 ASoC: Updates for v3.15
Quite a busy release for ASoC this time, more on janitorial work than
 exciting new features but welcome nontheless:
 
  - Lots of cleanups from Takashi for enumerations; the original API for
    these was error prone so he's refactored lots of code to use more
    modern APIs which avoid issues.
  - Elimination of the ASoC level wrappers for I2C and SPI moving us
    closer to converting to regmap completely and avoiding some
    randconfig hassle.
  - Provide both manually and transparently locked DAPM APIs rather than
    a mix of the two fixing some concurrency issues.
  - Start converting CODEC drivers to use separate bus interface drivers
    rather than having them all in one file helping avoid dependency
    issues.
  - DPCM support for Intel Haswell and Bay Trail platforms.
  - Lots of work on improvements for simple-card, DaVinci and the Renesas
    rcar drivers.
  - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
    CSR SiRF SoC.

6dda27cbbd ASoC: Intel: sst-acpi: Add support for multiple machine drivers per platform
Initial implementation of this driver focused only matching SST ACPI ID
with single machine driver and same firmware file per platform. It was known
restriction to be improved incrementally.

This patch is now changing this that SST ACPI ID refers purely to platform
specific data which refers to machine drivers on this platform, not vice
versa.

Matching machine driver is found by looking at ACPI ID which would best
match with the driver. Typically this would be the ACPI ID of audio codec
but is not tied to it.

This patch also changes that DSP firmware name is machine not platform
specific.

e5161d7987 ASoC: Intel: sst-acpi: Request firmware before SST platform driver probing
We originally thought to request SST audio DSP firmware during the SST
platform driver initialization. However plain request_firmware doesn't
work in driver probe paths if userspace is not ready to handle it. For
instance when drivers are built-in.

Implementing asynchronous firmware request in SST platform driver
initialization complicates code needlessly since it anyway will fail if
firmware is missing.

This is more simple to handle by requesting firmware asynchronously in
sst_acpi_probe() and register SST platform only after firmware is loaded.

c2f8783fa2 ASoC: Intel: Add common SST driver loader on ACPI systems
Most of the SST devices will be exposed as ACPI devices. It makes sense to
avoid duplication of the driver enumeration logic and concentrate the functionality
into a single ACPI SST enumeration file.

Idea of this loader is to parse data we get from ACPI and to be able to load
needed other SST drivers and ASoC machine driver runtime based on single
ACPI ID what BIOS gives to us.

790aff6229 ASoC: Intel: Add Intel SST audio DSP low level shim driver.
Add support for Intel Smart Sound Technology (SST) audio DSPs.
This driver provides the low level IO, reset, boot and IRQ management
for Intel audio DSPs. These files make up  the low level part of the SST
audio driver stack and will be used by many Intel SST cores like
Haswell, Broadwell and Baytrail.

SST DSPs expose a memory mapped region (shim) for config and control.
The shim layout is mostly shared without much modification across cores
and this driver provides a uniform API to access the shim and to enable
basic shim functions. It also provides functionality to abstract some shim
functions for cores with different shim features.

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.
