    ASoC: core: Don't schedule deferred_resume_work twice

    commit 82e14e8bdd88b69018fe757192b01dd98582905e upstream.

    For cards that have two or more DAIs, snd_soc_resume's loop over all
    DAIs ends up calling schedule_work(deferred_resume_work) once per DAI.
    Since this is the same work item each time, the 2nd and subsequent
    calls return 0 (work item already queued), and trigger the dev_err
    message below stating that a work item may have been lost.

    Solve this by adjusting the loop to simply calculate whether to run the
    resume work immediately or defer it, and then call schedule work (or not)
    one time based on that.

    Note: This has not been tested in mainline, but only in chromeos-2.6.38;
    mainline doesn't support suspend/resume on Tegra, nor does the mainline
    Tegra ASoC driver contain multiple DAIs. It has been compile-checked in
    mainline.

ENGR00172374-5: GPIO: use chained_irq_enter/exit pair

commit 1a01753ed90a4fb84357b9b592e50564c07737f7
Author: Will Deacon <will.deacon@arm.com>
Date:   Wed Feb 9 12:01:12 2011 +0000

    ARM: gic: use handle_fasteoi_irq for SPIs

    Currently, the gic uses handle_level_irq for handling SPIs (Shared
    Peripheral Interrupts), requiring active interrupts to be masked at
    the distributor level during IRQ handling.

    On a virtualised system, only the CPU interfaces are virtualised in
    hardware. Accesses to the distributor must be trapped by the
    hypervisor, adding latency to the critical interrupt path in Linux.

    This patch modifies the GIC code to use handle_fasteoi_irq for handling
    interrupts, which only requires us to signal EOI to the CPU interface
    when handling is complete. Cascaded IRQ handling is also updated to use
    the chained IRQ enter/exit functions to honour the flow control of the
    parent chip.

    Note that commit 846afbd1 ("GIC: Dont disable INT in ack callback")
    broke cascading interrupts by forgetting to add IRQ masking. This is
    no longer an issue because the unmask call is now unnecessary.

    Tested on Versatile Express and Realview EB (1176 w/ cascaded GICs).

- Only 44.1Khz audio are supported at i.MX6q, since only 44.1Khz
local playback are supported at i.MX6q.

- Since there is no feedback at current usb audio framework,
it may have pop noise/no sound after play some minutes.

- About how to test: please refer Documentation/arm/imx/udc.txt

ENGR00170901-2 IMX/UART : add a wait queue for DMA RX in SMP

The DMA RX thread may run on another CPU, while the application
runs on one CPU.

The application will close the uart when it finishes the required reading.
But the DMA RX thread maybe still running in this situation.

So add a wait queue to synchronize the __TWO__ sides in the SMP.
