Subject: [linux][PATCH v2 1/4] dt-bindings: display: bridge: add sam9x75-lvds compatible
Add the 'sam9x75-lvds' compatible binding, which describes the Low Voltage
Differential Signaling (LVDS) Controller found on some Microchip's sam9x7
series System-on-Chip (SoC) devices. This binding will be used to define
the properties and configuration for the LVDS Controller in DT.

Changelog
v1 -> v2
- Remove '|' in description, as there is no formatting to preserve.
- Remove 'gclk' from clock-names as there is only one clock(pclk).
- Remove the unused headers and include only used ones.
- Change the compatible name specific to SoC (sam9x75) instead of entire series.
- Change file name to match the compatible name.
