Early availability feature tree : kernel-display
Following features/patchsets were merged in 2.6.39
- Hwmod conversion of DSS2 - OMAP2/3
- Hwmod conversion of DSS2 - OMAP4
- Making DSS clock names common across all platforms
- Internal-clock-framework (calculation clock dividors for pixel clock for DSI1)
- Using hwmod opt-clocks for DSS
- Setting TAAL panel timings via bootargs
- Basic HDMI support (no HPD, Deep color, EDID)
- DVI support for Panda
