This reverts commit 5163fb6254
("ahci: added support for Freescale AHCI sata")
The reverted patch added Freescale QorIQ AHCI sata support to
ahci_platform driver though, but it left SoC specific settings to uboot.
It leads to QorIQ sata heavily depending on uboot. In order to removing
the dependency we first revert the old patch and then will add a new driver
for QorIQ SATA.
Since there are no LS* platforms that have been upstreamed, So
the revert would not break anything exists.

As part of testing ahci_st driver working on stih407 I noticed
several things wrong in the DT documentation: -
1) Compatible string doesn't match the driver code
2) pwr-rst reset isn't documented (but exists in the driver)
3) some whitespace issues (spaces not tabs)
Also add in a stih407 family example into the doc.

- Explicit documentation about which compatible strings are actually

Orignally written by Olliver Schinagl using the approach of having a platform
device which probe method creates a new child platform device which gets
driven by ahci_platform.c, as done by ahci_imx.c .
Refactored by Hans de Goede to add most of the non sunxi specific functionality
to ahci_platform.c and use a platform_data pointer from of_device_id for the
sunxi specific bits.

The sata_mv driver supports the SATA IP found in several Marvell SoCs.
As some new SATA registers have been introduced with the Armada 370/XP
SoCs, a way to identify them is needed.
This patch introduces a new compatible string for the SATA IP found in
Armada 370/XP SoCs.

Some SGPIO PICs don't follow the standard very well and expect a certain
number of clock cycles or port frames in each SGPIO pattern. Add two
optional parameters in the DTB that can provide the number of extra
clock cycles to be sent before and after SGPIO pattern. Read those
parameters from the DTB and send the extra clock cycles.

Some board designs do not drive the SATA transmit lines within the
specification. The ECME can provide override settings, on a per board
basis, to bring the transmit lines within spec. Read those settings
from the DTB and program them in.
At the time of submission, no production hardware requires this patch.

The Calxeda sata_highbank driver has been adding its descriptions to the
ahci driver. Separate them properly. This patch only affects
documentation and has no functional component.

Pull libata updates from Tejun Heo:
"Overview of changes:
- The rest of maintainer email address updates.
- Some core updates - more robust default behavior for port
multipliers, better error reporting for SG_IO commands, and a way
to better work around now ancient and probably pretty rare PATA ->
SATA bridges with ATAPI devices.
- sata_rcar stabilization.
- Some hardware PCI ID additions and one-off low level driver
updates."

functionality.

These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle.
We normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time
we need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc cleanup
series because of interdependencies with timer drivers now moved out
of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes
for Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10.
