Merge branch 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2015-06-25T23:49:21+00:00

Pull libata updates from Tejun Heo:

 - a number of libata core changes to better support NCQ TRIM.

 - ahci now supports MSI-X in single IRQ mode to support a new
   controller which doesn't implement MSI or INTX.

 - ahci now supports edge-triggered IRQ mode to support a new controller
   which for some odd reason did edge-triggered IRQ.

 - the usual controller support additions and changes.

ata: ahci_mvebu: add suspend/resume support

2015-06-17T18:25:53+00:00

This commit adds suspend/resume support to the ahci_mvebu driver. The
suspend hook doesn't do anything special despite calling the generic
ahci_platform_suspend_host() function. However, the resume hook has to
restore the MBus windows configuration, as well as the regret option.

Tested on Marvell Armada 388 GP.

ata: ahci_mvebu: Fix wrongly set base address for the MBus window setting

2015-05-26T18:46:15+00:00

According to the Armada 38x datasheet, the window base address
registers value is set in bits [31:4] of the register and corresponds
to the transaction address bits [47:20].

Therefore, the 32bit base address value should be shifted right by
20bits and left by 4bits, resulting in 16 bit shift right.

The bug as not been noticed yet because if the memory available on
the platform is less than 2GB, then the base address is zero.

ata: ahci_platform: fix owner module reference mismatch for scsi host

2015-01-28T23:45:23+00:00

The owner module reference of the ahci platform's scsi_host is
initialized to libahci_platform's one, because these drivers use a
scsi_host_template defined in libahci_platform.  So these drivers can
be unloaded even if the scsi device is being accessed.

This fixes it by pushing the scsi_host_template from libahci_platform
to all leaf drivers.  The scsi_host_template is passed through a new
argument of ahci_platform_init_host().

ata: drop owner assignment from platform_drivers

2014-10-20T14:20:17+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

ata: libahci_platform: move port_map parameters into the AHCI structure

2014-07-30T19:39:46+00:00

This patch moves force_port_map and mask_port_map into the
ahci_host_priv structure. This allows to modify them into the AHCI
framework. This is needed by the new dt bindings representing ports as
the port_map mask is computed automatically.

Parameters modifying force_port_map, mask_port_map and flags have been
removed from the ahci_platform_init_host() function, and inputs in the
ahci_host_priv structure are now directly filed.

libahci_platform: add host_flags parameter in ahci_platform_init_host()

2014-05-14T17:07:10+00:00

Add a dynamic host_flags argument to make ahci_platform_init_host more flexible,
then remove the AHCI_HFLAGS(...) argument from some driver's ata_port_info,
and pass that in as the new argument.

ata: ahci_mvebu: new driver for Marvell Armada 380 AHCI interfaces

2014-05-04T19:28:59+00:00

The Marvell Armada 380 SoC includes two AHCI compatible
interfaces. However, like all DMA-capable Marvell interface, they
require special handling to configure MBus windows. Therefore, this
commit adds a new ahci_mvebu driver, which relies on the
libahci_platform.c code recently introduced.
