Subject: [PATCH v3 0/8] arm64: ti: k3-am62: Add display support

Hi all,

Reviving this old patch series, after a long time. This was paused
because the compatible for the Display SubSystem (DSS) had to be
changed, along with the driver.

The patch series adds DT nodes for Display SubSystem (DSS) and other
peripherals required to enable the HDMI audio and video on the AM625 SK,
AM62-LP SK, as well as the AM625 based Beagle-Play platforms. An HDMI
monitor can be connected to the boards for the audio/video outputs.

The series adding the compatible and basic driver support[0] is in the
drm-misc-next and linux-next queues and is expected to be in the
mainline by v6.6-rc1.

Patches 5 and 7 have been picked up from TI's linux tree[1] based off
linux-kernel v6.1.

Change Log:
V2 -> V3:
  - Updated the compatible from "ti,am65x-dss" to "ti,am625-dss".
  - Peripheral nodes like HDMI TX, HDMI connector are now added to
    k3-am62x-sk-common.dtsi instead of k3-am625-sk.dts, in order to
    support AM62-LP SK-EVM as well.
  - Dropped the HDMI master clock node as it is not connected on the
    EVM, and should not have been added in the first place.
  - Re-worded and Re-ordered commits.
  - Dropped Rahul Ravikumar's R-bs because of the changes.
  - Added AM625 based Beagle-Play for HDMI support.
  - Added HDMI audio support as well.

V1 -> V2:
 - Removed repetitive data in dss_ports
