From: Devarsh Thakkar <devarsht@ti.com>
Add DSS, DSI, DPHY, and HDMI bridge nodes to enable DPI-to-HDMI output
on AM62L[1]. The DSS uses parallel DPI interface with pinctrl
configuration to drive an external SiI9022 HDMI bridge.
DSI and DPHY nodes are added but remain disabled, as the AM62L shares a
single video port for DPI and DSI output.
DSI functionality can be enabled via overlays when required.

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The `dpi_pins_default` pinctrl is incorrectly assigned to the external `sii9022` I2C bridge node instead of the SoC's `dss` node.
- [Low] The `dsi0` node is missing the required `ports` subnode, which will cause a device tree schema validation failure.

Author: Devarsh Thakkar <devarsht@ti.com>
arm64: dts: ti: k3-am62l: Add HDMI & DSI support
Adds DSS, DSI, DPHY, and HDMI bridge nodes to enable DPI-to-HDMI output on
AM62L. The DSI functionality is added but kept disabled, as it shares a
video port with DPI output.

[Severity: Low]
Does this node need a ports subnode to comply with the device tree schema?
The ti,j721e-dsi compatible string binds to the Cadence DSI schema which
strictly requires the ports property and its port@1 subnode for the DPI
input. Even though status is disabled, omitting the required properties in
the skeleton dtsi might cause dtbs_check to report schema validation errors
during compilation.

[Severity: Medium]
Should these pinctrl properties be placed in the dss node instead of here?
The dpi_pins_default node configures VOUT0 pins which are driven by the
AM62L internal Display Subsystem (DSS). Placing this pinmux in the external
sii9022 bridge node seems to create a dependency where the SoC's video
output pins are only multiplexed when the external I2C device driver loads.
If the bridge driver fails to probe or is unbound, the pins might remain
unconfigured or floating, even if the DSS attempts to use them.

I think you should add port information for dsi as well
see DSI node in other SOC (J721E, J721S2, J784s4) for reference.

1. please split this up. please dont mix the SoC with evm stuff.
2. I suggest DPI output be a overlay as well

I see you addressed sashiko comments
https://lore.kernel.org/all/20260514112012.0B0D0C2BCB3@smtp.kernel.org/
but i dont see evidence of HPD working. logs please for the next rev.
