This patch fixes the DP audio and video PLL configurations for the
zynqmp-zcu106-revA evaluation board.
The Linux DP driver expects the DP to be using the following PLL config:
- DP video PLL should use the VPLL (0x0)
- DP audio PLL should use the RPLL (0x3)
Register 0xFD1A0070 configures the DP video PLL.
Register 0xFD1A0074 configures the DP audio PLL.
This patch was build and run tested on a zynqmp-zcu106-revA target board.
Upstream-Status: submitted (https://lore.kernel.org/all/62538b4a04dee28a6fc8ac5b85f8c845a5a76aa4.1651740988.git.michal.simek@amd.com/)
This patch will be removed from buildroot in a future release when no longer necessary.

Xilinx ZCU102 / ZCU106 boards - ZynqMP SoC
******************************************
This document describes the Buildroot support for the ZCU102 and
ZCU106 boards by Xilinx, based on the Zynq UltraScale+ MPSoC (aka
ZynqMP). It has been tested with the ZCU102 and ZCU106 production
boards.
Evaluation board features can be found here with the links below.

How to build it
===============
Configure Buildroot:
$ make zynqmp_zcu106_defconfig
Compile everything and build the rootfs image:
$ make
Result of the build
-------------------
After building, you should get a tree like this:
output/images/
+-- atf-uboot.ub
+-- bl31.bin
+-- boot.bin
+-- boot.vfat
+-- Image
+-- rootfs.ext2
+-- rootfs.ext4 -> rootfs.ext2
+-- sdcard.img
+-- system.dtb -> zynqmp-zcu106-revA.dtb
+-- u-boot.itb
`-- zynqmp-zcu106-revA.dtb
How to write the SD card
========================
WARNING! This will destroy all the card content. Use with care!
The sdcard.img file is a complete bootable image ready to be written
on the boot medium. To install it, simply copy the image to an SD
card:
# dd if=output/images/sdcard.img of=/dev/sdX
Where 'sdX' is the device node of the SD.
Eject the SD card, insert it in the board, and power it up.
