  • 8eede5bc4   ata: ahci_platform: Add shutdown handler ... Browse Code »

    The newly introduced ahci_platform_shutdown() method is called during
    system shutdown to disable host controller DMA and interrupts in order
    to avoid potentially corrupting or otherwise interfering with a new
    kernel being started with kexec.

  • 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().

  • c7d7ddee7   ata: libahci: Allow using multiple regulators ... Browse Code »

    The current implementation of the libahci allows using multiple PHYs
    but not multiple regulators. This patch adds the support of multiple
    regulators. Until now it was mandatory to have a PHY under a subnode,
    now a port subnode can contain either a regulator or a PHY (or both).

    In order to be able to asociate a port with a regulator the port are
    now a platform device in the device tree case.

    There was only one driver which used directly the regulator field of
    the ahci_host_priv structure. To preserve the bisectability the change
    in the ahci_imx driver was done in the same patch.

  • 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.

    These members are not used anywhere, and in the future we want
    ahci_platform_data to go away entirely so there is no reason to keep these
    around.

  • 23b07d4cb   ahci-platform: "Library-ise" ahci_probe functionality ... Browse Code »

    ahci_probe consists of 3 steps:
    1) Get resources (get mmio, clks, regulator)
    2) Enable resources, handled by ahci_platform_enable_resouces
    3) The more or less standard ahci-host controller init sequence

    This commit refactors step 1 and 3 into separate functions, so the platform
    drivers for AHCI implementations which need a specific order in step 2,
    and / or need to do some custom register poking at some time, can re-use
    ahci-platform.c code without needing to copy and paste it.

    Note that ahci_platform_init_host's prototype takes the 3 non function
    members of ahci_platform_data as arguments, the idea is that drivers using
    the new exported utility functions will not use ahci_platform_data at all,
    and hopefully in the future ahci_platform_data can go away entirely.

    Some AHCI implementations may use Vendor Specific HBA[A0h, FFh]
    and/or Port[70h, 7Fh] registers to 'prepare' for initialization.
    For that, the platform needs memory mapped address of AHCI registers.

    This patch adds the 'mmio' argument and reorders the call to
    platform init function.
