Subject: [PATCH RFC 05/13] dt-bindings: mfd: Add starfive,jh7110-hdmi-mfd
Add the dt-binding for the StarFive JH7110 HDMI MFD (Multi-Function
Device).
The JH7110 HDMI IP is a monolithic block containing both the digital
controller and analog PHY in a single register space. This binding
defines the MFD parent device, which holds the shared register map and
populates its two children: the PHY and the controller. This is
necessary to resolve a circular clock dependency between the HDMI block
and the VOUT clock generator.
