  • b6338bdc8   ARM: 6649/1: omap: use fncpy to copy the PM code functions to SRAM ... Browse Code »

    The new fncpy API is better suited* for copying some
    code to SRAM at runtime. This patch changes the ad-hoc
    code to the more generic fncpy API.

    *: 1. fncpy ensures that the thumb mode bit is propagated,
    2. fncpy provides the security of type safety between the
    original function and the sram function pointer.

    Tested OK on OMAP3 in low power modes (RET/OFF)
    using omap2plus_defconfig with !CONFIG_THUMB2_KERNEL.
    Compile tested on OMAP1/2 using omap1_defconfig.

    Boot tested on OMAP1 & OMAP2
    Tested OK with suspend/resume on OMAP2420/n810

    Boots fine on osk5912 and n800

  • ce491cf85   omap: headers: Move remaining headers from include/mach to include/plat ... Browse Code »

    Move the remaining headers under plat-omap/include/mach
    to plat-omap/include/plat. Also search and replace the
    files using these headers to include using the right path.

    This was done with:

    #!/bin/bash
    mach_dir_old="arch/arm/plat-omap/include/mach"
    plat_dir_new="arch/arm/plat-omap/include/plat"
    headers=$(cd $mach_dir_old && ls *.h)
    omap_dirs="arch/arm/*omap*/ \
    drivers/video/omap \
    sound/soc/omap"
    other_files="drivers/leds/leds-ams-delta.c \
    drivers/mfd/menelaus.c \
    drivers/mfd/twl4030-core.c \
    drivers/mtd/nand/ams-delta.c"

    for header in $headers; do
    old="#include

  • 8bd229492   OMAP2/3: PM: push core PM code from linux-omap ... Browse Code »

    This patch is to sync the core linux-omap PM code with mainline. This
    code has evolved and been used for a while the linux-omap tree, but
    the attempt here is to finally get this into mainline.

    Following this will be a series of patches from the 'PM branch' of the
    linux-omap tree to add full PM hardware support from the linux-omap
    tree.

    Much of this PM core code was written by Jouni Hogander with
    significant contributions from Paul Walmsley as well as many others
    from Nokia, Texas Instruments and linux-omap community.

  • 0dc23d704   ARM: OMAP: fix fault in enter_full_retention() ... Browse Code »

    In omap24xx_cpu_suspend assembly routine, the r2 register which holds
    the address of the SDRC_POWER reg is set to zero before the value is
    written back triggering a fault due to writing to address zero.

    It's hard to tell where this change was introduced since this file
    has been moved and merged.

    While this fix prevents a crash, suspend on my n810 is broken with
    current kernels. I never come out of suspend.

  • 1835f1d72   ARM: OMAP2: Move sleep.S into sleep24xx.S ... Browse Code »

    Some register offsets are different for 242x and 243x. This
    will allow compiling sleep code for both chips into the same
    kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the
    omap24xx_cpu_suspend instead of loading the values since the only.

    Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL
    instead of the address as that's what omap24xx_cpu_suspend expects to
    determine between DDR and SDR. This bug has not been noticed as
    the boards seem to have DDR instead of SDR.

    Note that some PM patches are still missing. The PM patches will
    be added later on once the base files are in sync with linux-omap
    tree.
