We always store the register address as __iomem but pass it around as a plain void * which upsets sparse. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Ensure SYSCLK is enabled while running accessory detection on WM8958. It is always required so there is no sense in requiring machine drivers to individually do this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

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.

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.

Currently the SigmaDSP firmware loader only works correctly on little-endian systems. Fix this by using the proper endianess conversion functions.

The firmware header is not part of the CRC, so skip it. Otherwise the firmware will be rejected due to non-matching CRCs.

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.

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. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

We can reduce the code size here a bit by using snd_soc_update_bits instead of open-coding the read-modify-write cycle. The conversion done in this patch is not completely straightforward and some minor code restructuring has been incorporated to further reduce the code size.
