    MIPS: JZ4740: A320: Updated quickstart documentation.

    Mention the new ILI9338.
    Removed the instructions to change the kernel command line for 64 MB RAM
    on A330, since that is autodetected now if the 64 MB boot loader is used.

    MIPS: JZ4740: A320: Debounce microswitch buttons.

    On the microswitch buttons of the Dingoo A320 (L/R/select/start), it often
    happens that multiple presses are detected for one actual button press.
    Specifying a 5 ms debounce interval fixes that issue. I am not sure what
    the optimum interval length would be, but 5 ms is short enough to not cause
    problems for gamers and long enough to filter out the glitches.

    MIPS: JZ4740: reset: Initialize hibernate wakeup counters.

    In hibernation mode only the wakeup logic and the RTC are left running,
    so this is what users perceive as power down.
    
    If the counters are not initialized, the corresponding pin (typically
    connected to the power button) has to be asserted for two seconds
    before the device wakes up. Most users expect a shorter wakeup time.
    
    I took the timing values of 100 ms and 60 ms from BouKiCHi's patch for
    the Dingoo A320 kernel.

    MIPS: JZ4740: A320: defconfig: Enabled suspend.

    With the addition of cpufreq support in the MMC driver, we can come out
    of suspend without getting I/O errors from the SD card.

    MIPS: JZ4740: cpufreq: select CPU_FREQ_TABLE

    The driver calls cpufreq_frequency_table_target() unconditionally.
    Also changed the indentation to tabs, which seems to be the norm.

    MIPS: JZ4740: A320: defconfig: Re-enabled cpufreq driver.

    With recent changes the SD card access is reliable again when changing
    the CPU frequency.

    MMC: JZ4740: Added support for CPU frequency changing.

    The MSC device clock is stopped before the frequency change.
    After the change a new divider is computed and the clock is restarted.
    Also the frequency change is postponed if an I/O operation is in progress.

    MIPS: JZ4740: cpufreq: Set CE bit after PLL freq change.

    This fixes I/O errors when reading from SD card.
    I guess this is a hardware quirk: I even tried writing the current value
    with the same routine and that had no effect, so it is not some side effect
    that avoids the I/O errors, it is actually the CE bit that matters.

    MIPS: JZ4740: A320: defconfig: Disable CPU frequency scaling for now.

    I get I/O errors reading from the SD card when the cpufreq driver is
    used. In earlier kernels we had SD problems with cpufreq and suspend,
    but in 2.6.39 it also shows up under normal use. Until this problem
    is fixed in the cpufreq driver, it's better to disable it.

    MIPS: JZ4740: USB: Fix packet read/write functions.

    The read_packet() and write_packet() functions were recently converted
    to use memcpy_fromio() and memcpy_toio(). However, the FIFO register
    is only a single address while memcpy increases the address. Fixed by
    using readsl() and writesl() instead.

    MTD: NAND: JZ4740: Multi-bank support with autodetection

    The platform data can now specify which external memory banks to probe
    for NAND chips, and in which order. Banks that contain a NAND are used
    and the other banks are freed.

    MIPS: JZ4740: setup: Autodetect physical memory.

    Assume that the boot loader knows the physical memory of the system and
    deduce that information from the contents of the SDRAM control register.
    It is still possible to override with with the "mem=" parameter, but we
    have a sensible default now.

    MIPS: Implement flush_kernel_dcache_page().

    This is just a quick fix: a real fix would implement flush_kernel_vmap_range() and invalidate_kernel_vmap_range() as well, but those are only used in XFS for which we have no need on the Dingoo.

    /dev/mem: Add kernel config option to omit this device.

    Omitting this device prevents software from accessing the hardware directly, which can cause trouble if the kernel accesses the same hardware.

    mtd: cc_ftl: New FTL driver for media players using China Chip firmware.

    Tested on Dingoo A320: the FAT partition on the NAND is mounted successfully.
    Read-only for now.
    Not robust against bad FTL admin data yet: the driver won't crash, but it might return unnecessary I/O errors.

    PM: Remove sysdev suspend, resume and shutdown operations

    Since suspend, resume and shutdown operations in struct sysdev_class
    and struct sysdev_driver are not used any more, remove them.  Also
    drop sysdev_suspend(), sysdev_resume() and sysdev_shutdown() used
    for executing those operations and modify all of their users
    accordingly.  This reduces kernel code size quite a bit and reduces
    its complexity.

    PM / MIPS: Use struct syscore_ops instead of sysdevs for PM

    Convert some MIPS architecture's code to using struct syscore_ops
    objects for power management instead of sysdev classes and sysdevs.
    
    This simplifies the code and reduces the kernel's memory footprint.
    It also is necessary for removing sysdevs from the kernel entirely in
    the future.

    gpio-charger: Add gpio_charger_resume

    Gpio charger should notify if the gpio state had changed
    during suspend. This will send a CHANGED event each time
    the system resumes, ensuring a plug/unplug of the charger
    is not missed.

    NAND: Optimize reading the eec data for the JZ4740 (evil hack)

    We know that the ecc data is continuous, this allows us to only read the ecc
    data instead of the whole oob section, which slightly improves performance.
    
    Note that this is an evil hack, which will break platforms where the ecc data is
    non-continuous.
