    Subject[PATCH] [27/50] ARM: pxa/cm-x300: fix V3020 RTC functionality
    Date
    2.6.35-longterm review patch.  If anyone has any objections, please let me know.

    ------------------
    From: Igor Grinberg <grinberg@compulab.co.il>

    [ upstream commit 6c7b3ea52e345ab614edb91d3f0e9f3bb3713871 ]

    While in sleep mode the CS# and other V3020 RTC GPIOs must be driven
    high, otherwise V3020 RTC fails to keep the right time in sleep mode.
