Subject: [PATCH v4 1/2] dt-bindings: phy: add mediatek MIPI CD-PHY module v0.5

From: Florian Sylvestre <[email protected]>

This adds the bindings, for the MIPI CD-PHY module v0.5 embedded in
some Mediatek soc, such as the mt8365

+ The SENINF CD-PHY is a set of CD-PHY connected to the SENINF CSI-2
+ receivers. The number of PHYs depends on the SoC model.
+ Depending on the SoC model, each PHYs can be either CD-PHY or D-PHY only
+ capable.
