  • c8c3dcb9d   [ARM] locomo: fix unpaired spin_lock_irqsave ... Browse Code »

    The function locomo_m62332_senddata sends a three byte i2c message to
    a M62332 DAC. This entire function is guarded with a spin_lock_irqsave
    at the start of the function and a spin_unlock_irqrestore at the end.

    As each byte is transferred, the i2c ACK from the DAC is checked.
    Currently, if the ACK is missing the function simply returns without
    the unlock. It also leaves the i2c bus in an invalid state since the
    last byte transferred did not have a "stop" condition and leave the
    bus idle.

    Fix this by adding an exit path using goto.

  • 1b0d76cb9   [ARM] locomo: fix SPI register offset ... Browse Code »

    The locomo spi registers are all defined in locomo.h as offsets
    from the first spi register LOCOMO_SPI (0x60), which is itself
    an offset from the locomo base address. To correctly access
    these registers LOCOMO_SPI must always be included in the
    address calculation.

    There are two places in locomo.c where this is not done. The
    first one, in locomo_suspend, actually results in a write to
    LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe
    and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE.

    Fix these by including LOCOMO_SPI in the calculation.

  • 93160c639   PM: do not use saved_state from struct dev_pm_info on ARM ... Browse Code »

    The saved_state member of 'struct dev_pm_info' that's going to be removed
    is used in arch/arm/common/locomo.c, arch/arm/common/sa1111.c and
    arch/arm/mach-sa1100/neponset.c. Change the code in there to use local
    variables for saving the state of devices during suspend.

  • 38c677cb9   [ARM] 3739/1: genirq updates: irq_chip, add and use irq_chip.name ... Browse Code »

    Patch from David Brownell

    ARM genirq cleanups/updates:

    - Start switching platforms to newer APIs
    * use "irq_chip" name, not "irqchip"
    * providing irq_chip.name

    - Show irq_chip.name in /proc/interrupts, like on x86.

    This update a bit more than half of the ARM code. The irq_chip.name
    values were chosen to match docs (if I have them) or be otherwise
    obvious ("FPGA", "CPLD", or matching the code).

  • 9480e307c   [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks ... Browse Code »

    In PM v1, all devices were called at SUSPEND_DISABLE level. Then
    all devices were called at SUSPEND_SAVE_STATE level, and finally
    SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
    compatibility for platform devices, I arranged for the PM v2
    suspend/resume callbacks to call the old PM v1 suspend/resume
    callbacks three times with each level in order so that existing
    drivers continued to work.

    Since this is obsolete infrastructure which is no longer necessary,
    we can remove it. Here's an (untested) patch to do exactly that.
