ata: sata_mv: fix disk hotplug for Armada 370/XP SoCs

2014-02-06T19:08:16+00:00

commit 9013d64e661fc2a37a1742670202171c27fef4b5 upstream.

On Armada 370/XP SoCs, once a disk is removed from a SATA port, then the
re-plug events are not detected by the sata_mv driver. This patch fixes
the issue by updating the PHY speed in the LP_PHY_CTL register (0x58)
according to the SControl speed.

Note that this fix is only applied if the compatible string
"marvell,armada-370-sata" is found in the SATA DT node.

ata: sata_mv: introduce compatible string "marvell, armada-370-sata"

2014-02-06T19:08:15+00:00

commit b1f5c73bd5a4752efb7d7af019034044b08aafe9 upstream.

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.

Drivers: ata: remove __dev* attributes.

2013-01-03T23:57:03+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

sata_mv: Fix warnings when no PCI

2012-10-02T02:53:23+00:00

Dove can be configured without PCI. We then get a number of warnings:

warning: 'msi' defined but not used
warning: 'mv5_sht' defined but not used
warning: 'mv_dump_pci_cfg' defined but not used.

Move around variables and add #ifdef as necassary to fix the warnings.

ATA: sata_mv: Add device tree support

2012-07-27T14:48:45+00:00

Add support for instantiating this driver from device tree, and add
the necassary DT information to the kirkwood.dtsi file.

This is based on previous work by Michael Walle and Jason Cooper.

The Orion kirkwood chips have a gatable clock per SATA channel. Add
code to get and enable this clk if it exists.

sata_mv: silence an uninitialized variable warning

2012-04-12T19:57:22+00:00

Gcc version 4.6.2-12 complains that if we can't find the "nr-ports"
property in of_property_read_u32_array() then "n_ports" is used
uninitialized.  Let's set it to zero in that case.

ARM: Orion: Get address map from plat-orion instead of via platform_data

2011-12-13T23:46:55+00:00

Use an getter function in plat-orion/addr-map.c to get the address map
structure, rather than pass it to drivers in the platform_data
structures. When the drivers are built for none orion platforms, a
dummy function is provided instead which returns NULL.

sata_mv: use {platform|pci}_get_drvdata()

2011-10-08T03:46:20+00:00

The driver uses dev_get_drvdata() to get to the driver data for the
platform and PCI devices, while the corresponding wrappers exists for
them -- in one case it even declares an otherwise unneeded variable
to do that.  Switch to using the {platform|pci}_get_drvdata() instead.
