Subject: [PATCH 4.14 395/496] dt-bindings: add device tree binding for Allwinner H6 main CCU

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Icenowy Zheng <icenowy@...c.io>

[ 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.
