dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code.
This patch adds support for mt8195-dpintf to this dpi driver. Main differences are:
- Some features/functional components are not available for dpintf which are now excluded from code execution once is_dpintf is set
- dpintf can and needs to choose between different clockdividers based on the clockspeed. This is done by choosing a different clock parent.
- There are two additional clocks that need to be managed. These are only set for dpintf and will be set to NULL if not supplied. The clk_* calls handle these as normal clocks then.
- Some register contents differ slightly between the two components. To work around this I added register bits/masks with a DPINTF_ prefix and use them where different.
Based on a separate driver for dpintf created by Jason-JH.Lin jason-jh.lin@mediatek.com.
