From 1ded879e12310b1f8f81b1f84e293933a3b69f14 Mon Sep 17 00:00:00 2001 From: Chunyan Zhang Date: Thu, 7 Dec 2017 20:57:04 +0800 Subject: clk: move clock common macros out from vendor directories These macros are used by more than one SoC vendor platforms, avoid to have many copies of these code, this patch moves them to the common header file which every clock drivers can access to.
