From d5a04dddf51e234dc89f21e4e4b91e853cf49ff2 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Tue, 3 Mar 2015 16:08:42 +0200 Subject: [PATCH] clk: ti: omap2430: move clock support code under clock driver With the legacy clock support gone, this is no longer needed under platform code-base. Thus, move this under the TI clock driver, and remove the exported API from the public header.
