From mboxrd@z Thu Jan 1 00:00:00 1970 From: Russell King - ARM Linux Subject: [PATCH 0/5] imx ahci DT updates + cubox-i eSATA support Date: Wed, 16 Apr 2014 09:42:27 +0100 Message-ID: <20140416084227.GD24070@n2100.arm.linux.org.uk> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-ide-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org Cc: devicetree@vger.kernel.org, Ian Campbell , Kumar Gala , linux-ide@vger.kernel.org, Mark Rutland , Pawel Moll , Rob Herring , Sascha Hauer , Shawn Guo , Tejun Heo List-Id: devicetree@vger.kernel.org The following series adds several DT properties to the iMX ahci driver, which are necessary to configure the electrical characteristics of the SATA interface. The required electrical characteristics are board dependent, so the existing solution where the parameters are hard-coded for the first board(s) which came along is completely rediculous, and cause their own set of problems: we have to default to these parameters when no properties are given, and it means we have to use negative properties to turn stuff off rather than positive properties to enable features. Yes, I know that the required Documentation/devicetree file is missing, I couldn't find the existing file to update for this driver with the new properties. :) arch/arm/boot/dts/imx6q-cubox-i.dts | 4 + drivers/ata/ahci_imx.c | 188 ++++++++++++++++++++++++++++++++++-- 2 files changed, 184 insertions(+), 8 deletions(-) -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it.
