Subject: [PATCH v2 0/4] dt-bindings: Introduce dual-link panels & panel-vendors

Hi all,

Microtips Technology Solutions USA, and Lincoln Technology Solutions are
2 display panel vendors, and the first 2 patches add their vendor
prefixes.

The third patch introduces a dt-binding for generic dual-link LVDS
panels. These panels do not have any documented constraints, except for
their timing characteristics. Further, these panels have 2 pixel-sinks.
In a dual-link connection between an LVDS encoder and the panel, one
sink accepts the odd set of LVDS pixels and the other, the even set.

The fourth patch introduces driver support for the 'panel-dual-lvds'
in the panel-lvds driver, by adding the compatible.

A lot of this has been based from the Advantech,idk-2121wr dual-link
panel[1] and Maxime's patches for generic LVDS panels[2] (which are
single-link by default.) and the discussions that happened before they
were finally merged.

Thank you!

Changes in V2:
==============
  - Rebased to latest linux-next.
  - Made dt-binding syntax corrections in Patch 3/4, based on comments
    by Krzysztof Kozlowski and Laurent Pinchart.
