-From: Eduardo Valentin <eduardo.valentin@indt.org.br>
-
-This patch transform mcbsp code into a very initial
-implementation of a platform driver.
-
-It also gets ride of ifdefs on mcbsp.c code.
-To do it, a platform data structure was defined.
-
-Platform devices are located in arch/arm/plat-omap/devices.c
-

+Subject: [PATCH 1/3] ARM: OMAP: SmartReflex driver, reference source and header files
+Date: Mon, 2 Jun 2008 14:30:12 +0300
+
+The following patch set integrates TI's SmartReflex driver. SmartReflex is a
+module that adjusts OMAP3 VDD1 and VDD2 operating voltages around the nominal
+values of current operating point depending on silicon characteristics and
+operating conditions.
+
+The driver creates two sysfs entries into /sys/power/ named "sr_vdd1_autocomp"
+and "sr_vdd2_autocomp" which can be used to activate SmartReflex modules 1 and
+2.
+
+Use the following commands to enable SmartReflex:
+
+echo -n 1 > /sys/power/sr_vdd1_autocomp
+echo -n 1 > /sys/power/sr_vdd2_autocomp
+
+To disable:
+
+echo -n 0 > /sys/power/sr_vdd1_autocomp
+echo -n 0 > /sys/power/sr_vdd2_autocomp
+
+This particular patch adds the TI reference source and header files for
+SmartReflex. Only modifications include minor styling to pass checkpatch.pl
+test.

+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.
