  • e0e2674b9   ata: ahci_st: fixup layering violations / drvdata errors ... Browse Code »

    Brian noticed while working on another SATA driver that uses libahci_platform,
    an error in this driver; it tries to the the driver data for its
    device, while libata also thinks it can set the driver data. See:

    ahci_platform_init_host()
    -> ata_host_alloc_pinfo()
    -> ata_host_alloc()
    -> dev_set_drvdata()

    So instead of sticking the IP-specific platform data into drvdata, let's
    use the plat_data variable that is reserved for this use.

    Addtionally plat_data isn't set until ahci_platform_init_host() has been
    called further down in probe(). So re-work the st_ahci_probe_resets and
    st_ahci_deassert_resets functions to take ahci_host_priv *hpriv as a
    parameter.

  • 9a1e75e11   ahci: st: st_configure_oob must be called after IP is clocked. ... Browse Code »

    Currently the ahci_st driver will hang the system on probe, as the
    st_configure_oob function does some register writes before the IP
    is clocked. This patch moves the function call to after
    ahci_platform_enable_resources (which enables the IP clock), and
    resolves the hang.

    Addtionally st_ahci_configure_oob should be called in the st_ahci_resume
    function, so we also rectify that ensuring it is also called after
    the IP clock has been enabled.

  • 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().

  • 725c7b570   ata: libahci_platform: move port_map parameters into the AHCI structure ... Browse Code »

    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.
