From b64a7cb92dcf6e0047fb524c08c90d5894ba4e39 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Fri, 14 Oct 2016 10:35:24 +0530 Subject: [PATCH] ARM: AMx3xx: Centralize early clock initialization This is similar to Commit 93e6253d11030 ("ARM: OMAP4/5: Centralize early clock initialization") that was done for OMAP4+, reflecting the same for AM33xx and AM43xx SoCs to centralize clock initialization.
