  • 95ec77c06   powerpc: Make ppc_md.{halt, restart} __noreturn ... Browse Code »

    powernv marks it's halt and restart calls as __noreturn. However,
    ppc_md does not have this annotation. Add the annotation to ppc_md,
    and then to every halt/restart function that is missing it.

    Additionally, I have verified that all of these functions do not
    return. Occasionally I have added a spin loop to be sure.

  • 9178ba294   powerpc: Convert power off logic to pm_power_off ... Browse Code »

    The generic Linux framework to power off the machine is a function pointer
    called pm_power_off. The trick about this pointer is that device drivers can
    potentially implement it rather than board files.

    Today on powerpc we set pm_power_off to invoke our generic full machine power
    off logic which then calls ppc_md.power_off to invoke machine specific power
    off.

    However, when we want to add a power off GPIO via the "gpio-poweroff" driver,
    this card house falls apart. That driver only registers itself if pm_power_off
    is NULL to ensure it doesn't override board specific logic. However, since we
    always set pm_power_off to the generic power off logic (which will just not
    power off the machine if no ppc_md.power_off call is implemented), we can't
    implement power off via the generic GPIO power off driver.

    To fix this up, let's get rid of the ppc_md.power_off logic and just always use
    pm_power_off as was intended. Then individual drivers such as the GPIO power off
    driver can implement power off logic via that function pointer.

    With this patch set applied and a few patches on top of QEMU that implement a
    power off GPIO on the virt e500 machine, I can successfully turn off my virtual
    machine after halt.

  • 1f8c486fa   powerpc/fsl: fsl_soc: remove 'fixed-link' parsing code ... Browse Code »

    Parsing and registration of fixed PHY devices was needed with the use of
    of_phy_connect_fixed_link() because this function was using the
    designated PHY address identifier (first cell of the property) as the
    address to bind the PHY on the emulated bus.

    Since commit 3be2a49e5c08d268f8af0dd4fe89a24ea8cdc339 ("of: provide a
    binding for fixed link PHYs") a new pair of functions has been
    introduced which allows for dynamic address allocation of these fixed
    PHY devices, but also parses the old 'fixed-link' 5-digit property.

    Registration of fixed PHY early in platform code was needed because we
    could not issue a fixed MDIO bus re-scan within network drivers. The
    fixed PHYs had to be registered before the network drivers would call
    of_phy_connect_fixed_link(). All of these caveats are solved now, such
    that we can safely remove of_add_fixed_phys() now.

    Replace FSL USB platform code by simple platform driver for
    creation of FSL USB platform devices.

    The driver creates platform devices based on the information
    from USB nodes in the flat device tree. This is the replacement
    for old arch fsl_soc usb code removed by this patch. The driver
    uses usual of-style binding, available EHCI-HCD and UDC
    drivers can be bound to the created devices. The new of-style
    driver additionaly instantiates USB OTG platform device, as the
    appropriate USB OTG driver will be added soon.

    - Don't duplicate platform data callbacks in mpc83xx_spi struct.

    configuration method. The old way used fields in einfo, which no longer
    exists. The new way is to create an MDIO device-tree node for each instance
    of gianfar, and create a tbi-handle property to associate ethernet controllers
    with the TBI PHYs they are connected to.

  • c132419e5   gianfar: Fix race in TBI/SerDes configuration ... Browse Code »

    The init_phy() function attaches to the PHY, then configures the
    SerDesTBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY
    (sort of) and is accessed via the gianfar's MDIO registers, using the
    functions gfar_local_mdio_read/write(), which don't do any locking.

    The previously attached PHY will start a work-queue on a timer, and
    probably an irq handler as well, which will talk to the PHY and thus use
    the MDIO bus. This uses phy_read/write(), which have locking, but not
    against the gfar_local_mdio versions.

    The result is that PHY code will try to use the MDIO bus at the same time
    as the SerDes setup code, corrupting the transfers.

    Setting up the SerDes before attaching to the PHY will insure that there is
    no race between the SerDes code and *our* PHY, but doesn't fix everything.
    Typically the PHYs for all gianfar devices are on the same MDIO bus, which
    is associated with the first gianfar device. This means that the first
    gianfar's SerDes code could corrupt the MDIO transfers for a different
    gianfar's PHY.

    The lock used by phy_read/write() is contained in the mii_bus structure,
    which is pointed to by the PHY. This is difficult to access from the
    gianfar drivers, as there is no link between a gianfar device and the
    mii_bus which shares the same MDIO registers. As far as the device layer
    and drivers are concerned they are two unrelated devices (which happen to
    share registers).

    Generally all gianfar devices' PHYs will be on the bus associated with the
    first gianfar. But this might not be the case, so simply locking the
    gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup
    code is going to use.

    We solve this by having the code that creates the gianfar platform device
    look in the device tree for an mdio device that shares the gianfar's
    registers. If one is found the ID of its platform device is saved in the
    gianfar's platform data.

    A new function in the gianfar mii code, gfar_get_miibus(), can use the bus
    ID to search through the platform devices for a gianfar_mdio device with
    the right ID. The platform device's driver data is the mii_bus structure,
    which the SerDes setup code can use to lock the current bus.
