Please don't send cover letters for single patches, if there is anything
that needs saying put it in the changelog of the patch or after the ---
if it's administrative stuff.  This reduces mail volume and ensures that 
any important information is recorded in the changelog rather than being
lost.

[PATCH v5 0/1] sti: add audio interface to the hdmi driver

[Arnaud Pouliquen]

This patchset implements audio interface in HDMI drm driver. Implementation is 
based on 
ASoC generic hdmi codec driver( https://patchwork.kernel.org/patch/8713141/). 

V5:
Helper functions are suppressed, following dicussion on IRC with Daniel 
Vetter.
request is that other drivers that can use helper are also updated
helper function patch will be proposed  in a next, separed patchset.
for this track, hdmi_audio_get_non_coherent_n is integrated in sti 
driver.

V4:
 fixes for "video: hdmi: add helper functions for N and CTS"
- typo error and additional comments
- cts_1_ratio computation
- warning reported by kbuild test robot
- add rounded value for 297/1.001 MHz

V3: 
 - video: hdmi: add helper function for N and CTS
  Also used on Mediatek platform 
(https://patchwork.kernel.org/patch/8887341)
  delta vs V2:
  - typo fixes
  - if/else code optimisation
 - drm: sti: Add ASoC generic hdmi codec support.
  - typo fixes
  - add audio registers in debugfs information

V2: RFC
https://patchwork.kernel.org/patch/8091531/("video: hdmi: add helper function 
for N and CTS")
https://patchwork.kernel.org/patch/8091561/("ASoC: hdmi-codec: Add hdmi-codec 
for external HDMI-encoders")
 - patch: video: hdmi: add helper function for N and CTS
 Fixes based on Russel King remarks
 - Duplicate function to have a separte treatment for coherent and
   non-coherent clocks
 - Add ratio field for alternate CTS value
 - Clock frequency in Hz for TMDS and audio clocks
 - Add information concerning clocks and CTS calculation. 

V1: 
This RFC is the implementation of audio HDMI on sti platform based on generic 
hdmi-codec driver:
https://patchwork.kernel.org/patch/7215271/ ("ASoC: hdmi-codec: Add 
hdmi-codec for external HDMI-encoders")
https://patchwork.kernel.org/patch/8062611/ ("video: hdmi: add helper 
function for N and CTS")
