6f526f0a86 ASoC: WM8903: Disallow all invalid gpio_cfg pdata values
The GPIO registers are 15 bits wide. Hence values, higher than 0x7fff are
not legal GPIO register values. Modify the pdata.gpio_cfg handling code
to reject all illegal values, not just WM8903_GPIO_NO_CONFIG (0x8000). This
will allow the later use of 0xffffffff as an invalid value in future device
tree bindings, meaning "don't touch this GPIO's configuration".

84b315ee89 ASoC: Drop unused state parameter from CODEC suspend callback
The existence of this parameter is purely historical. None of the CODEC drivers
uses it and we always pass in the same value anyway, so it should be safe to
remove it.

1ab97c8cad ASoC: Add signal generator widget type
A signal generator behaves as an input would but is not considered for
any of the special behaviour associated with external input pins. This
is especially useful when automatically working out not connected widgets.

af6b6fe41c ASoC: Implement support for WM1811A jack detection
The WM1811A features an advanced low power accessory detection subsystem
which allows the device to be maintained in a very low power state while
the system is idle without sacrificing any accessory detection features.

Implement software support for this, automatically managing the power
configuration of the device depending on the detected accessory.

38fd54ee38 ASoC: SigmaDSP: Add regmap support
Add support for loading the SigmaDSP firmware using regmap. This allows us
to transparently use SPI or I2C as the transport protocol on devices which
support them.

For now we keep the old I2C support since we have one user of this which is not
straight forward to convert to regmap, due to variable length registers.

40216ce7aa ASoC: Move SigmaDSP firmware loader to ASoC
It has been pointed out previously, that the firmware subsystem is not the right
place for the SigmaDSP firmware loader. Furthermore the SigmaDSP is currently
only used in audio products and we are aiming for better integration into the
ASoC framework in the future, with support for ALSA controls for firmware
parameters and support dynamic power management as well. So the natural choice
for the SigmaDSP firmware loader is the ASoC subsystem.

4f718a29fe firmware: Sigma: Prevent out of bounds memory access
The SigmaDSP firmware loader currently does not perform enough boundary size
checks when processing the firmware. As a result it is possible that a
malformed firmware can cause an out of bounds memory access.

This patch adds checks which ensure that both the action header and the payload
are completely inside the firmware data boundaries before processing them.

0a590b1de2 ASoC: Add basic 1277-EV1 Littlemill audio driver
The Littlemill audio card supports a number of pluggable miniboards,
normally for the WM8994 family of devices. As all these devices look
mostly the same from an external configuration point of view and are
runtime enumerable we can write a standard machine driver which will
work out of the box with any of them. Start doing that with the bare
bones of a driver, only supporting AIF1.

Future patches will flesh this out to be more fully featured.
