f5f85ee065 ata: fix i.MX AHCI driver dependencies
The ahci_imx driver is only needed on Freescale i.MX platforms so
don't let it be built on other platforms, except for build test
purpose.

74c03eb630 libata: make AHCI_XGENE depend on PHY_XGENE
AHCI_XGENE is only applicable on ARM64 but it can also be enabled for
compile testing; however, AHCI_XGENE selects PHY_XGENE which has other
arch specific dependencies.  This leads to the following warning when
enabling it on other archs for compile testing.

  warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct
  dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))

Selecting a config option which itself has dependencies can easily
lead to broken configurations.  For now, let's just make AHCI_XGENE
depend on PHY_XGENE which has all the necessary dependencies already.

Pull libata updates from Tejun Heo:
 "A lot of activities on libata side this time.

   - A lot of changes around ahci.  Various embedded platforms are
     implementing ahci controllers.  Some were built atop ahci_platform,
     others were doing their own things.  Hans made some structural
     changes to libahci and librarized ahci_platform so that ahci
     platform drivers can share more common code.  A couple platform
     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are
     scheduled to be removed).

   - Dan finishes the patchset to make libata PM operations
     asynchronous.  Combined with one patch being routed through scsi,
     this should speed resume measurably.

   - Various fixes and cleanups from Bartlomiej and others"

Add the new ahci_da850 host driver.

Platform changes needed to make DaVinci DA850 SATA AHCI support
fully functional are in the separate "ARM: davinci: da850: update

Please note that this driver doesn't have the superfluous clock
control code as clock is already handled by the generic AHCI
platform library code.

9236a76d9e ata: Fix CS55xx dependencies
As far as I know, the CS5520 and CS5530 chipsets were only used with
32-bit x86 Geode processors, so I think their drivers are only needed
on this architecture, except for build testing purpose.

While we're here, simplify the dependencies for the CS5535 driver.

The CS5536 was used with the Geode processors, but also on MIPS
Loongson/Lemote 2 systems, so let its driver be built for these two
architectures only, except for build testing purpose.

c5754b5220 ARM: sunxi: Add support for Allwinner SUNXi SoCs sata to ahci_platform
This patch adds support for the ahci sata controler found on Allwinner A10
and A20 SoCs to the ahci_platform driver.

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.

9e54eae23b ahci_imx: add ahci sata support on imx platforms
imx6q contains one Synopsys AHCI SATA controller, But it can't share
ahci_platform driver with other controllers because there are some
misalignments of the generic AHCI controller - the bits definitions of
the HBA registers, the Vendor Specific registers, the AHCI PHY clock
and the AHCI signals adjustment window(GPR13 register).

 - CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
   should be configured to be '1'

 - bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL
   should be set to be '1'.(default 0)

 - One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
   configured regarding to the frequency of AHB bus clock.

 - Configurations of the AHCI PHY clock, and the signal parameters of
   the GPR13

Setup its own ahci sata driver, contained the imx6q specific
initialized codes, re-use the generic ahci_platform driver, and keep
the generic ahci_platform driver clean as much as possible.

bb96961928 libata: make it clear that sata_inic162x is experimental
sata_inic162x never reached a state where it's reliable enough for
production use and data corruption is a relatively common occurrence.
Make the driver generate warning about the issues and mark the Kconfig
option as experimental.

If the situation doesn't improve, we'd be better off making it depend
on CONFIG_BROKEN.  Let's wait for several cycles and see if the kernel
message draws any attention.

81ec44a6c6 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 update from Martin Schwidefsky:
 "The most prominent change in this patch set is the software dirty bit
  patch for s390.  It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
  the page_test_and_clear_dirty primitive which makes the common memory
  management code a bit less obscure.

  Heiko fixed most of the PCI related fallout, more often than not
  missing GENERIC_HARDIRQS dependencies.  Notable is one of the 3270
  patches which adds an export to tty_io to be able to resize a tty.

  The rest is the usual bunch of cleanups and bug fixes."

afe7595118 libata: identify and init ZPODD devices
The ODD can be enabled for ZPODD if the following three conditions are
satisfied:
1 The ODD supports device attention;
2 The platform can runtime power off the ODD through ACPI;
3 The ODD is either slot type or drawer type.
For such ODDs, zpodd_init is called and a new structure is allocated for
it to store ZPODD related stuffs.

And the zpodd_dev_enabled function is used to test if ZPODD is currently
enabled for this ODD.

A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.

8996b89d6b ata: add platform driver for Calxeda AHCI controller
Calxeda highbank SATA phy has intermittent problems bringing up a link
with Gen3 drives. Retrying the phy hard reset can work-around this issue,
but each reset also disables spread spectrum support. The reset function
also needs to reprogram the phy to enable spread spectrum support.

Create a new driver based on ahci_platform to support the Calxeda Highbank
SATA controller.

and use the ATA subsystem instead.

Unfortunately I needed several tries to find out, that I needed the SFF
menu I had not selected before because I had never heard that term
before. I think it would have helped me, to have PATA or legacy IDE in
that item’s name.

Add basic support for pata on iMX. It has been tested only on imx51.
SDMA support will probably be added later so this version supports only
PIO.

v2:
  - enable only when needed IORDY
  - use dev_get_drvdata
v3:
  - add missing clk_put() calls
  - use platform_get_irq()
  - fix resume code to avoid disabling IORDY on resume
v4:
  - Remove EXPERIMENTAL and switch to depends on ARCH_MXC
  - Use devm_kzalloc()
  - make clock a must-have
  - Use only 1 ioremap

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

2ad2c320a1 pata_platform: Remove CONFIG_HAVE_PATA_PLATFORM's dependencies.
CONFIG_HAVE_PATA_PLATFORM, by virtue of where its defined, has a
dependency on CONFG_ATA and CONFIG_ATA_SFF.  This causes Kconfig
warnings when it is selected by various architectures, such as

  warning: (ARCH_VEXPRESS && <choice> || ARCH_RPC && <choice> || MACH_VPAC270 && ARCH_PXA || MACH_REALVIEW_PB11MP && ARCH_REALVIEW || MACH_REALVIEW_PBA8 && ARCH_REALVIEW || MACH_REALVIEW_PBX && ARCH_REALVIEW || MACH_BAST_IDE && ARCH_S3C2410 || MACH_ANUBIS && ARCH_S3C2410) selects HAVE_PATA_PLATFORM which has unmet direct dependencies (ATA && ATA_SFF)

Since this option is only used to control visibility of the
CONFIG_PATA_PLATFORM option and isn't itself visible in the menu,
it is straightforward to simply remove these dependencies rather
than adjust all the architectures.

pata_cs5536 does work on the other platforms(e.g. Loongson, a MIPS
