From 04647773d6481885447dc263673144053d3ec561 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 23 Jul 2021 17:34:07 -0700 Subject: [PATCH] dt-bindings: input: Convert ChipOne ICN8318 binding to a schema The ChipOne ICN8318 Touchscreen Controller is supported by Linux thanks to its device tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema.
