This patch set adds support for more resolutions and refresh rates to Samsung Exynos5 SoC series which contains hdmi transmitter (hdmi v1.4a compliant).
Given resoltuion will be supported or not, is decided by two factors: 1) Corresponding pixel clock is supported by hdmi PHY. 2) Mixer can generate the correspoding video timing.
All standard resolutions and pixel rate combinations are verified for the above limitations and are listed in hdmi driver. Any standard resolution supported by the monitor/tv will be comapared against this list.
We got 640x480, 720x576 and 1680x1050 and few more refresh rates enabled as a result to this exercise.
