commit: 6c7b3ea52e345ab614edb91d3f0e9f3bb3713871 From: Igor Grinberg <[email protected]> Date: Mon, 9 May 2011 14:41:46 +0300 Subject: [PATCH] ARM: pxa/cm-x300: fix V3020 RTC functionality
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.
