  • 2e6769013   ARM OMAP2+ GPMC: calculate GPMCFCLKDIVIDER based on WAITMONITORINGTIME ... Browse Code »

    The WAITMONITORINGTIME is expressed as a number of GPMC_CLK clock cycles,
    even though the access is defined as asynchronous, and no GPMC_CLK clock
    is provided to the external device. Still, GPMCFCLKDIVIDER is used as a divider
    for the GPMC clock, so it must be programmed to define the
    correct WAITMONITORINGTIME delay.

    Calculate GPMCFCLKDIVIDER independent of gpmc,sync-clk-ps in DT for
    pure asynchronous accesses, i.e. both read and write asynchronous.

  • e639cd5bf   ARM: OMAP2+: Prepare to move GPMC to drivers by platform data header ... Browse Code »

    We still need to support platform data for omap3 until it's booting
    in device tree only mode. So let's add platform_data/omap-gpmc.h for
    that, and a minimal linux/omap-gpmc.h for the save and restore used
    by the PM code.

    Let's also keep a minimal mach-omap2/gpmc.h still around to avoid
    churn on the board-*.c files. Once omap3 boots in device tree only
    mode, we can drop mach-omap2/gpmc.h and we can make the data
    structures in platform_data/omap-gpmc.h private to the GPMC driver.

    Note that we can now also remove gpmc-nand.h and gpmc-onenand.h.
