Has anyone reviewed these changes yet? I don't see any replies, nor are they in David's git tree. To me, they look mostly fine - the only issue I get is that the final patch doesn't apply cleanly to dw_hdmi.h since they're generated against a tree which has audio support merged. I also see no regressions on iMX6, so I think they can be merged. Unless anyone has any objections, I'll add these to my queue for David. Thanks. Wooh, thanks, I will send v4 now to improve the "drm: dw_hdmi/dw_hdmi-rockchip".

[PATCH v3 0/3] Improve eye-diagram & single-ended test for rk3288 hdmi
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, set CKLVL to 18 and TXLVL to 19 when pixel clock is 74.25MHz. set CKLVL to 13 and TXLVL to 13 when pixel clock is 148.5MHz. Changes in v3: - make commit message more readable - For pixel clock less than 148.5MHz, set txlvl to 20. 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.
