This option enables device driver support for the PWM channels on certain Atmel processors. Pulse Width Modulation is used for purposes including software controlled power-efficient backlights on LCD displays, motor control, and waveform generation.
This driver exports functions to enable/disble/config/free Pulse Width Modulation in the Analog Baseband Chip AB8500. It is used by led and backlight driver to control the intensity.
Select this if you want a library to allocate the Timer/Counter blocks found on many Atmel processors. This facilitates using these blocks by different drivers despite processor differences.
Select this to get a high precision clocksource based on a TC block with a 5+ MHz base clock rate. Two timer channels are combined to make a single 32-bit timer. When GENERIC_CLOCKEVENTS is defined, the third timer channel may be used as a clock event device supporting oneshot mode (delays of up to two seconds) based on the 32 KiHz clock.
Some chips provide more than one TC block, so you have the choice of which one to use for the clock framework. The other TC can be used for other purposes, such as PWM generation and interval timing.
This option enables device driver support for in-band access to the IBM RSA (Condor) service processor in eServer xSeries systems. The ibmasm device driver allows user space application to access ASM (Advanced Systems Management) functions on the service processor. The driver is meant to be used in conjunction with a user space API. The ibmasm driver also enables the OS to use the UART on the service processor board as a regular serial port. To make use of this feature serial driver support (CONFIG_SERIAL_8250) must be enabled. WARNING: This software may not be supported or function correctly on your IBM server. Please consult the IBM ServerProven website <http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/> for information on the specific driver level and support statement for your IBM server.

The PTI (Parallel Trace Interface) driver directs trace data routed from various parts in the system out through an Intel Penwell PTI port and out of the mobile device for analysis with a debugging tool (Lauterbach or Fido). You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.
This option enables basic support for the IOC4 chip on certain SGI IO controller cards (IO9, IO10, and PCI-RT).

Otherwise say N.
If you want support for Texas Instruments(R) Flash Media adapters you should select this option and then also choose an appropriate host adapter, such as 'TI Flash Media PCI74xx/PCI76xx host adapter support', if you have a TI PCI74xx compatible card reader, for example. You will also have to select some flash card format drivers. MMC/SD cards are supported via 'MMC/SD Card support: TI Flash Media MMC/SD Interface support (MMC_TIFM_SD)'. To compile this driver as a module, choose M here: the module will be called tifm_core.
This option enables support for Texas Instruments(R) PCI74xx and PCI76xx families of Flash Media adapters, found in many laptops. To make actual use of the device, you will have to select some flash card format drivers, as outlined in the TIFM_CORE Help. To compile this driver as a module, choose M here: the module will be called tifm_7xx1.

This option enables device driver support for Atmel Synchronized Serial Communication peripheral (SSC). The SSC peripheral supports a wide variety of serial frame based communications, i.e. I2S, SPI, etc. If unsure, say N.
Provides support for intelligent enclosures (bays which contain storage devices). You also need either a host driver (SCSI/ATA) which supports enclosures or a SCSI enclosure device (SES) to use these services.
An SGI machine can be divided into multiple Single System Images which act independently of each other and have hardware based memory protection from the others. Enabling this feature will allow for direct communication between SSIs based on a network adapter and DMA messaging.
This driver provides access to MFGPT functionality for other drivers that need timers. MFGPTs are available in the CS5535 and CS5536 companion chips that are found in AMD Geode and several other platforms. They have a better resolution and max interval than the generic PIT, and are suitable for use as high-res timers. You probably don't want to enable this manually; other drivers that make use of it should enable it.
MFGPTs on the CS5535 require an interrupt. The selected IRQ can be overridden as a module option as well as by driver that use the cs5535_mfgpt_ API; however, different architectures might want to use a different IRQ by default. This is here for architectures to set as necessary.
This driver provides a clock event source based on the MFGPT timer(s) in the CS5535 and CS5536 companion chips. MFGPTs have a better resolution and max interval than the generic PIT, and are suitable for use as high-res timers.
The channel interface driver allows applications to communicate with iLO management processors present on HP ProLiant servers. Upon loading, the driver creates /dev/hpilo/dXccbN files, which can be used to gather data from the management processor, via read and write system calls. To compile this driver as a module, choose M here: the module will be called hpilo.
The GRU is a hardware resource located in the system chipset. The GRU contains memory that can be mmapped into the user address space. This memory is used to communicate with the GRU to perform functions such as load/store, scatter/gather, bcopy, AMOs, etc. The GRU is directly accessed by user instructions using user virtual addresses. GRU instructions (ex., bcopy) use user virtual addresses for operands. If you are not running on a SGI UV system, say N.
This option enables addition debugging code for the SGI GRU driver. If you are unsure, say N.
