+To: linux-omap@vger.kernel.org
+Cc: Kalle Jokiniemi <ext-kalle.jokiniemi@nokia.com>
+Subject: [PATCH 3/3] ARM: OMAP: SmartReflex driver: integration to linux-omap
+Date: Fri, 6 Jun 2008 12:49:49 +0300
+Message-Id: <1212745789-13926-3-git-send-email-ext-kalle.jokiniemi@nokia.com>
+
+- Changed register accesses to use prm_{read,write}_mod_reg and
+ prm_{set,clear,rmw}_mod_reg_bits() functions instread of
+ "REG_X = REG_Y" type accesses.
+
+- Changed direct register clock enables/disables to clockframework calls.
+
+- replaced cpu-related #ifdefs with if (cpu_is_xxxx()) calls.
+
+- Added E-fuse support: Use silicon characteristics parameters from E-fuse
+
+- added smartreflex_disable/enable calls to pm34xx.c suspend function.
+
+- Added "SmartReflex support" entry into Kconfig under "System type->TI OMAP
+ Implementations". It depends on ARCH_OMAP34XX and TWL4030_CORE.
+
+- Added "SmartReflex testing support" Kconfig option for using hard coded
+ software parameters instead of E-fuse parameters.
+
+Signed-off-by: Kalle Jokiniemi <ext-kalle.jokiniemi@nokia.com>
