[PATCH 1/3] arm64: dts: ti: k3-am62: Add support for AM625 OLDI IO Control

[Wadim Egorov]

From: Aradhya Bhatia <a-bhatia1@ti.com>

Add TI DSS OLDI-IO control registers for AM625 DSS. This is a region of
12 32bit registers found in the TI AM625 CTRL_MMR0 register space[0].
They are used to control the characteristics of the OLDI DATA/CLK IO as
needed by the DSS display controller node.

[PATCH 3/3] arm64: dts: ti: am625-phyboard-lyra: Add Lincoln LCD185-101CT panel overlay

[Wadim Egorov]

The panel is a Lincoln Technology Solutions LCD185-101CT [0]. It is
a dual-link LVDS panel and supports WUXGA resolution (1920x1200).
Furthermore, it has an I2C based touch controller: Goodix-GT928.

Add an device tree overlay to support the Lincoln LCD185-101CT panel
in combination with the phyBOARD-Lyra-AM62x.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/v6.17-rc1-58-g7c1d13a14e61 (best guess, 1/2 blobs matched)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
