From b4edc2bedefd9e190cd65a26259e3fea4c56fc8f Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Fri, 16 Mar 2018 22:02:12 +0800 Subject: [PATCH] dt-bindings: add device tree binding for Allwinner H6 main CCU BugLink: http://bugs.launchpad.net/bugs/1786352 [ Upstream commit 2e08e4d2ff488424919d69dd211ac860a019ac1d ] The Allwinner H6 main CCU uses the internal oscillator of the SoC, which is different with old SoCs' main CCU. Add device tree binding for the Allwinner H6 main CCU.
