Subject: [RFC PATCH 0/3]
Date: Tue, 10 Feb 2015 22:16:31 +0800 [thread overview]
Message-ID: <1423577791-19238-1-git-send-email-ykk@rock-chips.com> (raw)
RK3288 hdmi eye-diagram test would fail when pixel clock is 148.5MHz,
and single-ended test would failed when display mode is 74.25MHz.
- Fix some code style, leave space for next patches.
- For hdmi eye-diagram test, we turn on the Transmitter Trailer-B and
improve slopeboost to 25%-30% decrease.
- For hdmi single-ended test, we set CKLVL & TXLVL to 17 when pixel
clock is 74.25MHz, keep CKLVL & TXLVL to 13 when pixel clock is 148.5MHz.
