Hi all,

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".

Changelogs:

 V1 ---> V2:
 - As per Paul's comments, add "const" to the argument "layer" of the
 function is_layer_vid, and just return the result of "==" operator, and
 add Acked-by from Paul. 
 - As per Paul's comments, fix some pattern errors and use FIELD_PREP()
 macro instead of *_SHIFT and use GENMASK/BIT to create *_MASK macros.

Thanks,
Quanyang
