From: Quanyang Wang quanyang.wang@windriver.com
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

Add a new function is_layer_vid() to simplify the code that judges if a layer is the video layer.

From: Quanyang Wang quanyang.wang@windriver.com
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.
