Merge tag 'asoc-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.9 A fairly quiet release for ASoC: - Support for a wider range of hardware in the compressed stream code. - The ability to mute capture streams as well as playback streams while inactive. - DT support for AK4642, FSI, Samsung I2S and WM8962. - AC'97 support for Tegra. - New driver for max98090, replacing the stub which was there. Due to dependencies we've also got support for asynchronous I/O in regmap and DTification of DMA support for Samsung platforms (used only by the I2S driver and SPI) merged here as well.
