From 39c29498ce7fbf9c28962775ed3e798a4ff68b78 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Thu, 30 Jun 2016 17:31:16 +0800 Subject: [PATCH] clk: imx: add clk api for supporting CLK_OPS_PARENT_ENABLE clocks IMX SoCs like i.MX7D requires using CLK_OPS_PARENT_ENABLE flags, adding the corresponding clock APIs variants for easily to use.
