ata: ahci-platform: Add ports-implemented DT bindings.

2016-04-01T14:30:30+00:00

On some SOCs PORTS_IMPL register value is never programmed by the
firmware and left at zero value. Which means that no sata ports are
available for software. AHCI driver used to cope up with this by
fabricating the port_map if the PORTS_IMPL register is read zero,
but recent patch broke this workaround as zero value was valid for
NVMe disks.

This patch adds ports-implemented DT bindings as workaround for this issue
in a way that DT can can override the PORTS_IMPL register in cases where
the firmware did not program it already.

Revert "ahci: added support for Freescale AHCI sata"

2015-09-08T16:30:06+00:00

This reverts commit 5163fb62541e
("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.

ata: ahci_platform: Add ACPI _CLS matching

2015-07-06T23:55:21+00:00

This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.

The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:

  Device (AHC0) // AHCI Controller
  {
    Name(_HID, "AMDI0600")
    Name (_CCA, 1)
    Name (_CLS, Package (3)
    {
      0x01, // Base Class: Mass Storage
      0x06, // Sub-Class: serial ATA
      0x01, // Interface: AHCI
    })
    Name (_CRS, ResourceTemplate ()
    {
      Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
      Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
    })
  }

Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.

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: 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.
