    Previously, pending interrupts in tscadc were causing HW_PEN interrupt,
    needed for wake from DS0, to get disabled immediately by IRQ handler
    after being enabled. Flush all pending interrupts in suspend handler
    before enabling HW_PENi interrupt so that this no longer happens and
    board is able to wake from DS0 on a touch event.

  • 7d9207c12   ARM: dts: am43xx: Remove MPU DS0 voltage scaling ... Browse Code »

    Currently am43xx handles MPU voltage scaling to 0.95v during sleep using
    CM3 firmware to write sequence to PMIC. This creates a problem during
    resume because sequence written to scale the voltage back is fixed at
    1.1v which may not agree with cpufreq governor. Because of the conflict
    here MPU voltage should be scaled manually to lowest OPP with cpufreq
    before suspend rather than doing it here.

  • be4c522b3   input: touchscreen: pixcir: also trigger IRQ on rising edge ... Browse Code »

    We want to make sure we never miss penup/down events
    and the easiest way is to also trigger IRQ on the rising
    edge.

    This will make sure that when we touch or release the
    touchscreen surface, an IRQ will be fired and our ISR
    handler will be called, thus avoiding missed events.

    CPSW driver TX and RX interrupt handling is not optimal. The driver handles
    both irq's together and relies on RX NAPI to proces the TX packet. Lets
    seperate the interrupt handling and convert the TX completion to NAPI as
    well.

    With these changes the network perfromance shoots up by almost 40 %
    for UDP. For TCP we also we get pretty good boost.

    Reverting the Advisory 1.0.13 leads to functional issues when multiple
    Mass Storage devices are connected. Especially when more than 3
    Mass Storage disks are connected it fails to mount the disks reliably.

  • d3d0710d9   ARM: config: Add HAVE_ARM_SCU for AM43XX ... Browse Code »

    CONFIG_HAVE_ARM_SCU only gets selected if CONFIG_SMP is selected in an OMAP
    system however AM43XX needs this option regardless of CONFIG_SMP as it is
    important for controlling power in the SoC. Without this suspend will
    not work as scu_power_mode becomes an empty function.

    AM43XX requires SCU CPU Power Status bits for A9 core to be set to off mode
    in order for the MSTANDBY signal to be asserted from the MPU during WFI.
    This signal is used by the PRCM to determine when it is appropriate to
    clock gate the MPU clock domain and also trigger M3_IRQ2 to tell the wkup_m3
    firmware to put the part into the desired sleep more.

    Add context_offs to the DSS hwmod for am43xx as the driver uses the
    context loss count to determine whether or not to restore context to the
    module. Also add prcm flag indicating this bit is valid. Without this the
    display does not return after a suspend cycle.

    In the case of am43xx, make sure we allow hwmods that don't use the hwmod
    context_offs for context loss counting to still use powerdomains to count
    context loss.

  • fe66c6993   ARM: OMAP2+: omap_hwmod: Add context ops to am43xx soc_ops ... Browse Code »

    AM43XX contains PRM_*_CONTEXT registers like OMAP4 did to track loss
    of context in modules so utilize the same get_context_loss_count soc_op
    present for OMAP4 but define a custom update context loss function for
    am43xx. Because we do not define context_offs for each hwmod, introduce
    a new flag to indicate when we have so we only bother to update when
    we know that it is valid.

    Certain drivers use the context loss count to determine if context was
    truly lost during a suspend operation to decide whether or not a
    context restore is truly necessary. Without this, some drivers may
    choose not to restore context when they have actually lost it and fail
    to properly resume.

  • 683e03034   ARM: OMAP2+: am43xx: Use omap4 prm context ops ... Browse Code »

    Context loss counting relies on several prm function pointers that
    serve as a "mapping" into the context loss registers and actually
    allow reading and clearing of the registers. Use the same
    from omap4 for am43xx as the layout of the prcm is similar.

    options and should be disabled in production kernel builds.

    Linux networking supports advanced networking features like IPSEC, NETFILTERS,
    BRIDGING etc and should be enabled only when user has specific usecase to
    use them. Thats why all typical distro's build them as modules so that all
    the standard network usecases don't get any additional overhead and specific
    case can load those modules when needed.

    Lets align the config accordingly. Created using typical 'savedefconfig' method.
