[RFC PATCH 00/15] Add SATA support for TI OMAP5 and DRA7 SoCs

[Roger Quadros <rogerq@ti.com>]

Hi,

This series adds SATA controller support for the Texas Instruments
OMAP5 and DRA7 platforms.

As the SATA controller is compatible with AHCI, we use the ahci_platform
driver and just provide the glue logic.

The AHCI controller is enclosed within a TI specific Wrapper that controls
the controller power mode. Patch 9 adds a driver for this wrapper.

The controller is linked to a SATA (PIPE3) PHY, which needs to be clocked
and powered up before it can be used. We do that with the help of the
generic PHY framework [2] in Patch 8.

Patches 1 to 7 adapt the the PHY driver to the Generic PHY framework.

Patches 9 to 15 provide platform adaptation code for OMAP5 and DRA7.

Patches are based on v3.12-rc1 with the following patches on top
[1] - omap control usb multiple instance support
      http://article.gmane.org/gmane.linux.ports.arm.kernel/267587
      git://github.com/rogerq/linux.git usb-control-module

[2] - Generic PHY framework
      git://git.kernel.org/pub/scm/linux/kernel/git/kishon/linux-phy.git testing

[3] - Clock DT support
      git://gitorious.org/~kristo/omap-pm/omap-pm-work.git mainline-3.11-rc3-omap-dt-clks-v5

[4] - PHY framework mis cleanup
      https://lkml.org/lkml/2013/9/2/313

NOTE: [2], [3] and [4] will cause merge conflicts and need to be resolved manually.
A merged tree is available for reference/testing at

git://github.com/rogerq/linux.git ti-3.12-sata

Tested on omap5-uevm and dra7-evm with Gen2 SATA hard drive.

Known issues:
- Gen3 SATA SSD does not work due to some issue with PHY speed negotiation.

cheers,
-roger
