From 10becdb402af4fd4808a0491a726b96128c41076 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marex@denx.de> Date: Mon, 25 Nov 2013 09:47:00 +0100 Subject: ahci: imx: Explicitly clear IMX6Q_GPR13_SATA_MPLL_CLK_EN From: Marek Vasut <marex@denx.de> commit 10becdb402af4fd4808a0491a726b96128c41076 upstream. We must clear this IMX6Q_GPR13_SATA_MPLL_CLK_EN bit on i.MX6Q, otherwise Linux will fail to find the attached drive on some boards.
