From 5fc56a8ea956f450e120d894d42c97880e0d9444 Mon Sep 17 00:00:00 2001 From: Chunfeng Yun Date: Wed, 30 Aug 2017 19:34:10 +0800 Subject: dt-bindings: mt8173-xhci: add generic compatible and rename file The mt8173-xhci.txt actually holds the bindings for all mediatek SoCs with xHCI controller, so add a generic compatible and change the name to mediatek,mtk-xhci.txt to reflect that.
