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. To fix such problems, we make those patch set: - 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 10%-20% decrease. - For hdmi single-ended test, we set CKLVL to 18 and & TXLVL to 19 when pixel clock is 74.25MHz, keep CKLVL & TXLVL to 13 when pixel clock is 148.5MHz. Changes in v2: - set slopeboost back to 10%-20%, then rasing/falling time would pass. - For pixel clock less than 74.25MHz, set txlvl to 19 and set cklvl to 18.
