-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 2/3] ARM: OMAP: SmartReflex driver: added required register and bit definitions.
-Date: Fri, 6 Jun 2008 12:49:48 +0300
-
-Added new register and bit definitions to enable Smartreflex driver integration.
-Also PRM_VC_SMPS_SA bit definitions' naming was changed to match the naming of
-other similar bit definitions.

-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.
-

-+ SmartReflex can perform continuous dynamic voltage

-+ Please note, that by default SmartReflex is only
