Subject: [PATCH v4 10/15] drm: bridge/dw_hdmi: add audio sample channel status setting
Date: Sat, 28 Feb 2015 21:49:47 -0500 [thread overview]
Message-ID: <1425178187-2278-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1425175834-24661-1-git-send-email-ykk@rock-chips.com>
From: Daniel Kurtz <djkurtz@chromium.org>
When transmitting IEC60985 linear PCM audio, we configure the
Audio Sample Channel Status information of all the channel
status bits in the IEC60958 frame.
Signed-off-by: Yakir Yang <ykk@rock-chips.com>
---
Changes in v4:
- Give HDMI_FC_AUD_SCHNL8 an readable value
Changes in v3:
- Determine whether sample channel should set by desig_id.
Changes in v2:
- Add audio sample channel status setting
