  • 17dcc37e3   ata: ahci-platform: Add ports-implemented DT bindings. ... Browse Code »

    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.

    Fixes: 566d1827df2e ("libata: disable forced PORTS_IMPL for >= AHCI 1.3")

    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.

  • 2051e9248   ata: ahci_platform: Add ACPI _CLS matching ... Browse Code »

    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.

  • 018d5ef20   ata: ahci_platform: fix owner module reference mismatch for scsi host ... Browse Code »

    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().

    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.

    In order to save power consumption as much as possible.

    * Disable sata phy internal pll reference clock when sysetem enter
    into suspend mode, enable it after resume.

    * Setup module parameter used to enable imx ahci test power down
    mode(PDDQ) or not, when there is no device detected on the port

    * minor modifications:
    - The format of the copyright is changed, because that the original
    one can't pass fsl internal patch reivew without the character
    '(c)'.
    - Exports ahci_platform_ops and ahci_error_handler().

    NOTE:
    * The hot-plug can't be supported when PDDQ mode is ever enabled.

    * module parameter usage how-to:
    - default: enable PDDQ mode when no device detected.
    - add "ahci-imx.hotplug=1" into kernel command line if your don't
    want to enable PDDQ mode when no device detected on the port.

    tj: Slightly updated description and comments.

    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.

    AHCI platform devices may provide an exit() routine, via
    ahci_platform_data, that powers off the SATA core. Such a routine should
    be executed from the ata_port_operations host_stop() hook. That way, the
    ATA subsystem can perform any last-minute hardware cleanup (via devres,
    for example), then trigger the power-off at the appropriate time.

    This patch fixes bus errors triggered during module removal or device
    unbinding, seen on an SoC SATA core.

    platform_driver_probe() should be used for registering this driver only
    if we want to

    "...remove its run-once probe() infrastructure from memory after the
    driver has bound to the device."

    However, we may want to leave the probe infrastructure in place in order
    to support binding/unbinding a device dynamically. This is useful, for
    instance, as a power management mechanism, where a device can be totally
    powered down when unbound (whereas with runtime power management,
    powering down the SATA core would incur unacceptable loss of
    functionality).

    Thus, convert this driver to use platform_driver_register().
