    Subject[PATCH AUTOSEL for-4.4 06/39] ARM: dts: Fix omap3 off mode pull defines
    Date
    From: Tony Lindgren <tony@atomide.com>

    [ Upstream commit d97556c8012015901a3ce77f46960078139cd79d ]

    We need to also have OFFPULLUDENABLE bit set to use the off mode pull values.
    Otherwise the line is pulled down internally if no external pull exists.

    This is has some documentation at:

    http://processors.wiki.ti.com/index.php/Optimizing_OMAP35x_and_AM/DM37x_OFF_mode_PAD_configuration

    Note that the value is still glitchy during off mode transitions as documented
    in spz319f.pdf "Advisory 1.45". It's best to use external pulls instead of
    relying on the internal ones for off mode and even then anything pulled up
    will get driven down momentarily on off mode restore for GPIO banks other
    than bank1.
