From: Maxime Ripard Date: Thu, 27 Jan 2022 14:30:44 +0000 (+0100) Subject: dt-bindings: display: Turn lvds.yaml into a generic schema X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ea8a12e350e86aaa5fe7815db864b35fae2356f1;p=linux.git dt-bindings: display: Turn lvds.yaml into a generic schema The lvds.yaml file so far was both defining the generic LVDS properties (such as data-mapping) that could be used for any LVDS sink, but also the panel-lvds binding. That last binding was to describe LVDS panels simple enough, and had a number of other bindings using it as a base to specialise it further. However, this situation makes it fairly hard to extend and reuse both the generic parts, and the panel-lvds itself. Let's remove the panel-lvds parts and leave only the generic LVDS properties.
