2014-07-01dt-bindings: ata: add ahci_imx electrical propertiesRussell King1-0/+8
Add the documentation for the electrical properties for the iMX SATA controller. There are many values for these, and listing them would be error prone. Refer readers to the device documentation and driver source code for these details.

2014-07-01dt-bindings: ata: create bindings for imx sata controllerShawn Guo1-0/+26
To: Tejun Heo <tj@kernel.org>,linux-ide@vger.kernel.org The Freescale i.MX SATA controller mostly conforms to the AHCI interface, but there are some special extensions at integration level like clocks settings and hardware parameters. Let's create a separate bindings doc for imx sata controller, so that more imx specific properties can be added later without messing up the generic ahci-platform bindings.
