[019/102] ARM: pxa/cm-x300: fix V3020 RTC functionality

From: Greg KH
Date: Wed Aug 03 2011 - 19:25:42 EST


3.0-stable review patch. If anyone has any objections, please let us know.

------------------

From: Igor Grinberg <grinberg@xxxxxxxxxxxxxx>

commit 6c7b3ea52e345ab614edb91d3f0e9f3bb3713871 upstream.

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.
