ASoC updates in 3.0

Linux 3.0 was released today – another fairly quiet release for the ASoC core, plus the usual collection of new drivers:

• Support DAPM controls that affect multiple paths – mainly used for single register bits that affect the routing for a stereo pair of audio streams.
• Simplifications in the cache infrastructure.
• New machine drivers for iPAQ hx4700, PCM hookup for WM8580 on Samsung reference platforms and Wolfson Speyside, plus a generalization of the Tegra Harmony driver to cover a range of other platforms based off a similar reference design.
• New CODEC drivers for AK4641, MAX98095 and WM8996.
