  • Wait a little bit longer, 50mS instead of 20mS, until the driver starts
    polling for pen-up. The problematic behavior before this patch is applied
    is as follows. The behavior was observed on the STMPE610QTR controller.

    Upon a physical pen-down event, the touchscreen reports one set of x-y-p
    coordinates and a pen-down event. After that, the pen-up polling is
    triggered and since the controller is not ready yet, the polling mistakenly
    detects a pen-up event while the physical state is still such that the pen
    is down on the touch surface.

    The pen-up handling flushes the controller FIFO, so after that, all the
    samples in the controller are discarded. The controller becomes ready
    shortly after this bogus pen-up handling and does generate again a pen-down
    interrupt. This time, the controller contains x-y-p samples which all read
    as zero. Since pressure value is zero, this set of samples is effectively
    ignored by userland.

    In the end, the driver just bounces between pen-down and bogus pen-up
    handling, generating no useful results. Fix this by giving the controller a
    bit more time before polling it for pen-up.

  • Problem reported by: Ted Kim :

    We have a case where a Linux system and a non-Linux system are
    trying to interoperate. The Linux host is the active side and
    starts the connection establishment, but later decides to not go
    through with the connection setup and does rdma_destroy_id().

    The rdma_destroy_id() eventually works its way down to cm_destroy_id()
    in core/cm.c, where a REJ is sent. The non-Linux system
    has some trouble recognizing the REJ because of:

    A. CM states which can't receive the REJ
    B. Some issues about REJ formatting (missing comm ID)

    ISSUE A: That part of the spec says, a Consumer Reject REJ can be
    sent for a connection abort, but it goes further
    and says: can send a REJ message with a "Consumer Reject"
    Reason code if they are in a CM state (i.e. REP
    Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows
    a REJ to be sent (lines 35-38).

    Of the states listed there in that sentence, it would
    seem to limit the active side to using the Consumer Reject
    (for the abort case) in just the REP-Rcvd and MRA-REP-Sent
    states. That is basically only after the active side
    sees a REP (or alternatively goes down the state transitions
    to timeout in which case a Timeout REJ is sent).

    As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case
    to the same as REQ-SENT. Essentially, make a REJ sent after
    getting an MRA on active side a timeout rather than Consumer-
    Reject, which is arguably more correct with the CM state
    diagrams previous to getting a REP.

  • This is an alternative way of fixing:
    commit db9683fb412d ("net: phy: Make sure PHY_RESUMING state change
    is always processed")

    When the PHY state transitions from PHY_HALTED to PHY_RESUMING, there are
    two things we need to do:
    1). Re-enable interrupts (and power up the physical link, if powered down)
    2). Update the PHY state and net-device based on the link status.

    There's no strict reason why #1 has to be done from within the main
    phy_state_machine() function. There is a risk that other changes to the
    PHY (e.g. setting speed/duplex, which calls phy_start_aneg()) could cause
    a subsequent state transition before phy_state_machine() has processed
    the PHY_RESUMING state change. This would leave the PHY with interrupts
    disabled and/or still in the BMCR_PDOWN/low-power mode.

    Moving enabling the interrupts and phy_resume() into phy_start() will
    guarantee this work always gets done. As the PHY is already in the HALTED
    state and interrupts are disabled, it shouldn't conflict with any work
    being done in phy_state_machine(). The downside of this change is that if
    the PHY_RESUMING state is ever entered from anywhere else, it'll also have
    to repeat this work.

  • We assumed all touch interfaces report touch data. But, Bamboo
    and Intuos non-touch devices report express keys on touch
    interface. We need to check touch_max before counting touches.

  • A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different
    VCPU than it is bound to. This can result in a race between
    handle_percpu_irq() and removing the action in __free_irq() because
    handle_percpu_irq() does not take desc->lock. The interrupt handler
    sees a NULL action and oopses.

    Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER).

  • The PWM hardware on Pistachio platform has a maximum timebase steps
    value to 255. To fix it, let's introduce a compatible-specific
    data structure to contain the SoC-specific details and use it to
    specify a maximum timebase.

    Also, let's limit the minimum timebase to 16 steps, to allow a sane
    range of duty cycle steps.

  • Don't pollute the dmesg with EDID read success message as an error.
    Printing as debug should be fine.

  • Remove the unused fields of struct exynos_drm_plane.

    v2: Remove index_color as well, also unused (thanks Joonyoung).

  • The index for the hardware layer is always >=0. Previous
    code that also used -1 as special index is now gone.

    Also apply this to 'ch_enabled' (decon/fimd), since the
    variable is on the same line (and is again always unsigned).
