From b138b0283d35bed0cd3353d7e39add8ac493eb37 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Mon, 2 Mar 2015 09:57:28 +0200 Subject: [PATCH] clk: ti: move generic OMAP DPLL implementation under drivers/clk With the legacy clock data now gone, we can start moving OMAP clock type implementations under clock driver. Start this with moving the generic OMAP DPLL clock type under TI clock driver.
