In Kria SOM configuration DP is under reset and access to DP is causing
hang that's why call reset at probe to avoid this situation.

3876abbbfc zynqmp: Avoid setting the framebuffer address
This is handled by driver model so this driver should not be setting the
framebuffer address. Drop the assignment.

d678a59d2d Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

322c0da86a video: zynqmp: Enable 1024x768 resolution
Add support for 1024x768 60p resolution and set it up this resolution by
default. This resolution is still able to use only one GT line. But for
example 800x600 60p has some issues with settings. That's why extend this
table by tested resolutions.

a29f44d631 video: zynqmp: Driver for Xilinx ZynqMP DisplayPort Subsystem
The Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPort
Subsystem. It includes a buffer manager, blender, an audio mixer and a
DisplayPort source controller (transmitter). The DisplayPort controller can
source data from memory (non-live input) or the stream (live input). The
DisplayPort controller is responsible for managing the link and physical
layer functionality. The controller packs audio/video data into transfer
units and sends them over the main link. The link rate and lane counts can
be selected based on the application bandwidth requirements. The
DisplayPort pipeline consists of the DisplayPort direct memory access (DMA)
for fetching data from memory. The DisplayPort DMA controller (DPDMA)
supports up to six input channels as non-live input.

This driver supports the DisplayPort Subsystem and implements
1)640x480 resolution
2)RGBA8888 32bpp format
3)DPDMA channel 3 for Graphics
4)Non-live input
5)Fixed 5.4G link rate
6)Tested on ZCU102 board

There will be additional work to configure GT lines based on DT, higher
resolutions, support for more compressed video formats, spliting code to
more files, add support for EDID, audio support, using clock framework for
all clocks and in general code clean up.
