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:
- 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one
iteration. Therefore, we add a new config "pixels_per_iter" to control
quantity of transferred pixels per iteration.
- Input of dp_intf is two pixels per iteration, so we add a new config
"input_2pixel" to control this.
- 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
