  Add SPDX license identifiers to all Make/Kconfig files which:

  - Have no license information of any form

  These files fall under the project license, GPL v2 only. The resulting SPDX
  license identifier is:

  GPL-2.0-only

• 372d855f8   ALSA: x86: Fold intel_hdmi_audio_if.c into main file ... Browse Code »

  As the very last step, we fold intel_hdmi_audio_if.c into the main
  file, intel_hdmi_audio.c. This is merely a cleanup, and no functional
  change.

  By this move, we can mark all functions and variables as static, which
  allows the compiler more optimizations.

• da8648097   ALSA: x86: Flatten two abstraction layers ... Browse Code »

  This is the final stage for a big clean-up series. Here we flatten
  the two layers into one. Formerly, the implementation was split to
  HDMI "shell" that talks with the platform device, and HDMI audio part
  that communicates via caps and other event handlers. All these would
  be good if there were multiple instantiations or if there were data
  protection. But neither are true in our case. That said, it'll be
  easier to have a flat driver structure in the end.

  In this patch, the former struct hdmi_lpe_audio_ctx is forged into the
  existing struct snd_intelhad. The latter has already a few members
  that are basically the copy from the former. Only a few new members
  for the lowlevel I/O are added by this change.

  Then, the had_get_caps() and had_set_caps() are simply replaced with
  the direct calls to copy the data in the struct fields. Also, the
  had_event_handler() calls are replaced with the direct call for each
  event as well.

• 5dab11d89   ALSA: x86: hdmi: Add audio support for BYT and CHT ... Browse Code »

  Hdmi audio driver based on the child platform device
  created by gfx driver is implemented.
  This audio driver is derived from legacy intel
  hdmi audio driver.

  The interfaces for interaction between gfx and audio
  are updated and the driver implementation updated to
  derive interrupts in its own address space based on
  irq chip framework

  The changes to calculate sub-period positions was triggered
  by David Henningsson and is
  accomodated in this patch

• 287599cf2   ALSA: add Intel HDMI LPE audio driver for BYT/CHT-T ... Browse Code »

  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
