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

* [PATCH 2/2] drm: xlnx: consolidate the functions which programming AUDIO_VIDEO_SELECT register

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.

* [PATCH 2/2] drm: xlnx: consolidate the functions which programming AUDIO_VIDEO_SELECT register
@ 2021-05-13 11:45 ` quanyang.wang

Cc: Quanyang Wang, linux-arm-kernel, dri-devel, linux-kernel
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.

The rest looks good.

I'd swap these two lines above - variables are usually defined in
"reverse christmas tree" order, the longest line first, the smallest

Please use BIT() or GENMASK(). You don't need the _SHIFT macros if you
use FIELD_PREP() / FIELD_GET().

Please use BIT() or GENMASK(). You don't need the _SHIFT macros if you
use FIELD_PREP() / FIELD_GET().

You can put 'mode' on a new line to avoid getting over 80 characters.

Please consider using the FIELD_PREP() macro from <linux/bitfield.h>.
Then you can get rid of your *_SHIFT macros.

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.
