Subject: [PATCH v5 0/6] arm64: ti: k3-am62: Add display support

Hi all,

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. Patch 5/6 also requires Nishanth Menon's patch[1]
that introduces debounce select mux macros. This patch too is not in
v6.5-rc1 but has been picked up in ti-next[2] and hence, is present in
linux-next.

Patches 4 and 5 have been picked up from TI's vendor tree[3] based off
linux-kernel v6.1.

Regards
Aradhya

Change Log:
V4 -> V5:
  - Cosmetic changes as suggested by Jayesh.
  - Fixed the mis-represented DSS VP1 clock, and added a
    fixed-factor-clock.

V3 -> V4:
  - Added "Fixes" tag for patch 1/6.
  - Rebased to linux-next.
  - Enabled display at board level and disabled at SoC level.
  - Dropped OLDI pinmux configuration as OLDI output comes directly from
    the SoC and muxing is not required.
  - Squashed DSS pinmux patches into their platform specific HDMI
    support patches, because it did not make sense to have only one set
    of pinmux config separated in a patch.

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
