Patch for the atmel-hlcdc driver:
Change pixel clock divider settings to resolve incorrect clock output
and reduce rounding to prevent clocking out of range.
Add support for the TDA19988 HDMI transmitter and possibly other
component based DRM drivers. Added device tree options to enable
required timing changes. The idea is based on the tilcdc driver. DRM
panels and bridges should still work with atmel-hlcdc, but this should
be tested as I only have hardware using the TDA19988.
This patch makes the atmel-hlcdc driver work with the tda998x, without
rewriting that driver to a DRM bridge.
