Subject: [PATCH v4 08/15] drm: bridge/dw_hdmi: add audio support for more display resolutions
Date: Sat, 28 Feb 2015 21:45:24 -0500 [thread overview]
Message-ID: <1425177924-2130-1-git-send-email-ykk@rock-chips.com> (raw)
In-Reply-To: <1425175834-24661-1-git-send-email-ykk@rock-chips.com>
Add more n/cts values, in that case we can support audio for more
display resolutions (128 * SampleRate = PixelClock * N / CTS).
Signed-off-by: Yakir Yang <ykk@rock-chips.com>

Changes in v4: None
Changes in v3: None
Changes in v2:
- add more n/cts combinations for more display resolutions
