This pach set is to bring back audio to machines with a LPC32XX CPU.
The legacy LPC32XX SoC used to have audio spport in linux 2.6.27.
The support was dropped due to lack of interest from mainaeners.

  ARM: dts: lpc32xx: Add missing properties for the i2s interfaces
  ARM: lpc32xx: Add pl08x virtual dma channels for spi and i2s
  ASoC: fsl: Add i2s and pcm drivers for LPC32xx CPUs
