From d93101abe41e9596555a0f7f6f775e543b71c441 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Wed, 31 Jan 2018 14:58:02 -0600 Subject: arm64: dts: stratix10: use clock bindings for the Stratix10 platform Use the clock bindings for the Stratix10 SoC. This includes changing the old binding of "intc,clk-s10-mgr" to "intel,stratix10-clkmgr". The reason that this can be done is that there are currently no clock driver for Stratix10, thus there are no consumers of the old binding. So changing the binding will not break any legacy code.
