      ALSA: add Intel HDMI LPE audio driver for BYT/CHT-T · 287599cf
      Jerome Anand authored
      On Baytrail and Cherrytrail, HDaudio may be fused out or disabled
      by the BIOS. This driver enables an alternate path to the i915
      display registers and DMA.
      Although there is no hardware path between i915 display and LPE/SST
      audio clusters, this HDMI capability is referred to in the documentation
      as "HDMI LPE Audio" so we keep the name for consistency. There is no
      hardware path or control dependencies with the LPE/SST DSP functionality.
      The hdmi-lpe-audio driver will be probed when the i915 driver creates
      a child platform device.
      Since this driver is neither SoC nor PCI, a new x86 folder is added
      Additional indirections in the code will be cleaned up in the next series
      to aid smoother DP integration
