This series greatly reworks DE2 mixer and accompanying DW-HDMI platform driver. Main goal was to use as many information from device tree as possible and thus removing SoC speficic ifdefs from the code. This was largely accomplished for mixer driver and mostly for HDMI driver.
Most of these changes are not user visible. Only improvements relevant to the user are filtering HDMI modes based on pixel clock and searching for additional detailed timings in EDID extension block. This change allows me to use 4k monitor that I have - base EDID block on this monitor holds only 4k@60 detailed timing. Other detailed timings, which are appropriate for HDMI 1.4 controller, are contained in extension block.
There is plenty of work to do. TCON handling should go to dedicated driver and clock related code in TCON and DW-HDMI code should be moved to clock drivers.
Testing was done only on H3.
Best regards, Jernej
