Huang Shijie [Wed, 18 Jan 2012 02:51:40 +0000 (10:51 +0800)]
ENGR00173731-3 mxs-dma : rewrite the last parameter of mxs_dma_prep_slave_sg()

[1] Background :
    The GPMI does ECC read page operation with a DMA chain consist of three DMA
    Command Structures. The middle one of the chain is used to enable the BCH,
    and read out the NAND page.

    The WAIT4END(wait for command end) is a comunication signal between
    the GPMI and MXS-DMA.

[2] The current DMA code sets the WAIT4END bit at the last one, such as:

    +-----+               +-----+                      +-----+
    | cmd | ------------> | cmd | ------------------>  | cmd |
    +-----+               +-----+                      +-----+
                                                          ^
                                                          |
                                                          |
                                                     set WAIT4END here

    This chain works fine in the mx23/mx28.

[3] But in the new GPMI version (used in MX50/MX60), the WAIT4END bit should
    be set not only at the last DMA Command Structure,
    but also at the middle one, such as:

    +-----+               +-----+                      +-----+
    | cmd | ------------> | cmd | ------------------>  | cmd |
    +-----+               +-----+                      +-----+
                             ^                            ^
                             |                            |
                             |                            |
                        set WAIT4END here too        set WAIT4END here

    If we do not set WAIT4END, the BCH maybe stalls in "ECC reading page" state.
    In the next ECC write page operation, a DMA-timeout occurs.
    This has been catched in the MX6Q board.

[4] In order to fix the bug, rewrite the last parameter of
    mxs_dma_prep_slave_sg(), and use the dma_ctrl_flags:
    ---------------------------------------------------------
      DMA_PREP_INTERRUPT : append a new DMA Command Structrue.
      DMA_CTRL_ACK       : set the WAIT4END bit for this DMA Command Structure.
    ---------------------------------------------------------

[5] changes to the relative drivers:
    For gpmi-nand driver: use the new flags.

    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

Kernel oops when plug in/out sd card and throw out null pointer

this is due to: commit: 1a01753 ARM: gic: use handle_fasteoi_irq for SPIs

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).
