, thanks for taking the
time.
The series is currently based on v5.14-rc5 but it requires other patches to
actually work on mt8195 (clock, etc.). A binding documentation is not included
yet.
Thanks,
Markus
Markus Schneider-Pargmann (5):
dt-bindings: mediatek,dpi: Add mt8195 dpintf
drm/mediatek
This patch adds two helper functions that extract the frequency and word
length from a struct cea_sad.
For these helper functions new defines are added that help translate the
'freq' and 'byte2' fields into real numbers.

DP_INTF is similar to the actual dpi. They differ in some points
regarding registers and what needs to be set but the function blocks

DP_INTF is a similar functional block to mediatek,dpi but is different
in that it serves the DisplayPort controller on mediatek SoCs and uses
different clocks. Therefore this patch creates a new binding file for
this functional block.

DP_INTF is similar to DPI but does not have the exact same feature set
or register layouts.
DP_INTF is the sink of the display pipeline that is connected to the
DisplayPort controller and encoder unit. It takes the same clocks as
DPI.
