-         Some thinkpad models benefit from NVRAM polling to detect a few of
-         the hot key press events.  If you know your ThinkPad model does not
-         need to do NVRAM polling to support any of the hot keys you use,
-         unselecting this option will save about 1kB of memory.

+       help
+         This option enables device driver support for the PWM channels
+         on the Cirrus EP93xx processors.  The EP9307 chip only has one
+         PWM channel all the others have two, the second channel is an
+         alternate function of the EGPIO14 pin.  A sysfs interface is
+         provided to control the PWM channels.

 
 

-         ThinkPads T40 and newer, R52 and newer, and X31 and newer are
-         unlikely to need NVRAM polling in their latest BIOS versions.
+         To compile this driver as a module, choose M here: the module will
+         be called ep93xx_pwm.

 
 

-         NVRAM polling can detect at most the following keys: ThinkPad/Access
-         IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
-         Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

-         If you are not sure, say Y here.  The driver enables polling only if
-         it is strictly necessary to do so.
+         This driver can also be built as a module.  If so, the module
