| |
2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Igor Grinberg <grinberg@compulab.co.il>
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.
