Message

This series adds support for:
- DisplayPort for J784S4-EVM
- Displayport and HDMI for AM69-SK platform

NOTE: Patch 4/5 introduces the following dtc warning which can be ignored
since its behind W=1 check:
Warning (graph_child_address): /bus@100000/dss@4a00000/ports: graph node
has single child node 'port@0', #address-cells/#size-cells are not
necessary

(This is more accurate description for port and the dtc check should not
differentiate between port@0 and port@1.[3])

Changelog v9->v10:
- Remove duplicate properties from dp0_ports node in main file.
- Add reg for the port even though there is only single port in dss_port
  since its more accurate description for the port.
- Carry the R-by tags from v9.

Changelog v8->v9:
- Fix compatible of serdes_ln_ctrl node
- Fix extra new lines across nodes
- Fix node-names to keep them generic

Changelog v7->v8:
- rebase on tag next-20230731
- add AM69 display support
- fix commit heading for patch [2/5]

Changelog v6->v7:
- change compatible for scm_conf to 'simple-bus'
- drop main_cpsw node due to driver dependency on [2]

Changelog v5->v6:
- Change header file according to [1].
- Add idle-state property in serdes_ln_ctrl node.
- Fix dtbs_check warning due to clock-frequency property in serdes_refclk
  node by disabling the node in main.dtsi and enabling it in board file
  when the clock-frequency node is actually added.

Changelog v4->v5:
- rebased the patches on linux-next tip.

Changelog v3->v4:
- add reg property to serdes_ln_ctrl and fix the node name again to
  get rid of dtbs_check error.
- reorder reg, reg-names and ranges property for main_cpsw1.
- correct the order for clocks in serdes_wiz nodes to fix dtbs_check
  warnings.
- fix indentation in reg, reg-names and clock property for dss node.
- add comments for the reg type in dss registers.

Changelog v3->v2:
- fix dtc warnings for 'scm_conf' and 'serdes_ln_ctrl' nodes
  (Checked all the changes of the series with W=12 option during build)
- added clock-frequency for serdes_refclk along with other EVM changes
  This refclk is being used by all the instances of serdes_wiz which
  are disabled by default. So configuring refclk when the serdes nodes
  are used for the first time is okay.

Changelog v1->v2:
- Moved J784S4 EVM changes together to the last patch
  (Suggested by Andrew)
