From e10781c118c986a3eb7c4b2edb4bdaba37bb5635 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Tue, 3 Dec 2019 15:12:41 +0100 Subject: [PATCH] dt-bindings: mfd: Document the Xylon LogiCVC multi-function device The LogiCVC is a display engine which also exposes GPIO functionality. For this reason, it is described as a multi-function device that is expected to provide register access to its children nodes for gpio and display.
