From: Quanyang Wang <[email protected]>
The patch "drm: xlnx: add is_layer_vid() to simplify the code" is to
simplify the code which judge the layer type.
The patch "drm: xlnx: consolidate the functions which programming AUDIO_VIDEO_SELECT register"
is to consolidate the code that can configure vid/gfx/audio to output
different mode (live/mem/disable/tpg) in one function "zynqmp_disp_avbuf_output_select".
Thanks,
Quanyang

2.25.1
From: Quanyang Wang <[email protected]>
For now, the functions zynqmp_disp_avbuf_enable/disable_audio and
zynqmp_disp_avbuf_enable/disable_video are all programming the register
AV_BUF_OUTPUT_AUDIO_VIDEO_SELECT to select the output for audio or video.
And in the future, many drm properties (like video_tpg, audio_tpg,
audio_pl, etc) also need to access it. So let's introduce some variables
of enum type and consolidate the code to unify handling this.

I'd swap these two lines above - variables are usually defined in
"reverse christmas tree" order, the longest line first, the smallest
line last. No big deal though.
