[PATCH v2 00/19] video: sunxi: rework DE2 driver

[Jernej Skrabec]

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, HDMI and HDMI PHY 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 at 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

Changes from v1:
- collected tags
- reword some commit messages
- dropped patch 13 and 14 from v1
- 2 new patches, first add HDMI PHY driver and another drops PHY
  code from sunxi dw-hdmi driver and uses separate driver instead
