Hi Sam,

Thank you for the patch.

With panel-timing converted, now convert the single remaining .txt user in panel/ of panel-timing to DT schema.

v2:

• Drop Thierry as maintainer, as this is not a general panel binding and I have no acks.
• Drop requirement for a panel- specific binding - "panel-dpi" is enough
• Updated example

v3:

• added yaml document terminator "..."
• always require a specific binding - panel-dpi (based on feedback from Rob)
• use "power-supply" for the supply property, and made it mandatory "power-supply" is the standard property for panels
