  • 1754aab9b   mtd: ATMEL, AVR32: inline nand partition table access ... Browse Code »
    43

    Currently atmel_nand driver used by AT91 and AVR32 calls a special callback
    which return nand partition table and number of partitions. However in all
    boards this callback returns just static data. So drop this callback and
    make atmel_nand use partition table provided statically via platform_data.

    Nicolas Ferre: I am in favor for a mainline inclusion through linux-mtd tree.
    Hans-Christian Egtvedt: I'm fine by sending the changes for AVR32 through linux-mtd

  • 64393b3ae   AT91: Change nand buswidth logic to match hardware default configuration ... Browse Code »

    The recently modified nand buswitth configuration is not aligned with
    board reality: the double footprint on boards is always populated with 8bits
    buswidth nand flashes.
    So we have to consider that without particular configuration the 8bits
    buswidth is selected by default.
    Moreover, the previous logic was always using !board_have_nand_8bit(), we
    change it to a simpler: board_have_nand_16bit().

    Since we're now using addruart to establish the debug mapping, we can
    remove the io_pg_offst and phys_io members of struct machine_desc.

    The various declarations were removed using the following script:

  • f6ed6f78d   Fix rename of at91_nand -> atmel_nand ... Browse Code »

    Structs called at91_nand_data where renamed to atmel_nand_data
    and configs called *MTD_NAND_AT91* where renamed to
    *MTD_NAND_ATMEL*. This was unfortunately not done consistently,
    causing NAND chips not being initialised on several ARM boards.

    I am aware that the author of the original change did not rename
    MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
    All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
    to keep naming consistency.

    This patch was only tested on a MACH_SAM9_L9260, as this is the
    only ARM board I have to my disposal.

    Before this patch:

    $ git-ls-files |xargs grep atmel_nand |wc -l
    105
    $ git-ls-files |xargs grep at91_nand |wc -l
    4
    $ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l
    8
    $ git-ls-files |xargs grep MTD_NAND_AT91 |wc -l
    47

    After this patch:

    $ git-ls-files |xargs grep atmel_nand |wc -l
    109
    $ git-ls-files |xargs grep at91_nand |wc -l
    0
    $ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l

  • a9a84c37d   atmel_lcdfb: backlight control ... Browse Code »

    On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
    the LCD controller. It's controlled by "contrast" registers though.

    This patch lets boards declare that they have that kind of backlight
    control. The driver can then export this control, letting screenblank and
    other operations actually take effect ... reducing the typically
    substantial power drain from the backlight.

    Note that it's not fully cooked
    - doesn't force backlight off during system suspend
    - the "power" and "blank" events may not be done right
    This should be easily added in the future.

    The Atmel AT91SAM9263 processor includes many more integrated
    peripherals than Atmel's previous ARM9-based AT91 processors, so this
    has necessitated a few changes to the core AT91 support.

    These changes are:
    * The system peripheral I/O region we remap has increased from
    0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
    * The increased I/O region forces changes to entry-macro.S and
    debug-macro.S due to ARM's limited immediate offset addressing
    modes.
    * Maximum number of GPIO banks increases to 5.
    * 2 MMC controllers so the board-setup code needs to specify which
    controller it wishes to use when calling at91_add_device_mmc().

    Original patch from Nicolas Ferre.
