ata: ahci-platform: Add ports-implemented DT bindings.

2016-05-17T18:31:17Z

[ Upstream commit 17dcc37e3e847bc0e67a5b1ec52471fcc6c18682 ] On some SOCs PORTS_IMPL register value is never programmed by the firmware and left at zero value. Which means that no sata ports are available for software. AHCI driver used to cope up with this by fabricating the port_map if the PORTS_IMPL register is read zero, but recent patch broke this workaround as zero value was valid for NVMe disks. This patch adds ports-implemented DT bindings as workaround for this issue in a way that DT can can override the PORTS_IMPL register in cases where the firmware did not program it already.

ata: qcom: Add device tree bindings information

2014-09-23T13:16:56Z

Add device tree binding for Qualcomm AHCI SATA controller and specifically the sata controller on the IPQ806x family of SoCs. We can utilize the "generic-ahci" platform driver with the addition of the sata phy to enable SATA support on Qualcomm SoCs with AHCI controllers.

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.

dt-bindings: ata: create bindings for imx sata controller

2014-07-01T21:24:39Z

To: Tejun Heo ,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.
