-+ help
-+ Select which GPIO pin to use for the CompactFlash CD
-+ signal. This is specified as a hexadecimal number and should
-+ be defined as 0x20 * gpio_port + pin.
-+
-+ The default is 0x3e, which is pin 30 on PIOB, aka GPIO15.
-+
-+config BOARD_ATSTK100X_ENABLE_PSIF
-+ bool "Enable PSIF peripheral (PS/2 support)"
-+ default n
-+ help
-+ Select this if you want to use the PSIF peripheral to hook up PS/2
-+ devices to your STK1000. This will require a hardware modification to
-+ work correctly, since PS/2 devices require 5 volt power and signals,
-+ while the STK1000 only provides 3.3 volt.
-+
-+ Say N if you have not modified the hardware to boost the voltage, say
-+ Y if you have level convertion hardware or a PS/2 device capable of
-+ operating on 3.3 volt.

-+ * NOTE: see warning above about repeated starts; this driver is falsely
-+ * claiming to support "combined" transfers. The mid-message STOPs mean
-+ * some slaves will never work with this driver. (Use i2c-gpio...)
++ * - Two channels combine to create a free-running 32 bit counter
++ * with a base rate of 5+ MHz, packaged as a clocksource (with
++ * resolution better than 200 nsec).
++ *
++ * - The third channel may be used to provide a 16-bit clockevent
++ * source, used in either periodic or oneshot mode. This runs
++ * at 32 KiHZ, and can handle delays of up to two seconds.
++ *
++ * A boot clocksource and clockevent source are also currently needed,
++ * unless the relevant platforms (ARM/AT91, AVR32/AT32) are changed so
++ * this code can be used when init_timers() is called, well before most
++ * devices are set up. (Some low end AT91 parts, which can run uClinux,
++ * have only the timers in one TC block... they currently don't support
++ * the tclib code, because of that initialization issue.)
++ *
++ * REVISIT behavior during system suspend states... we should disable
++ * all clocks and save the power. Easily done for clockevent devices,
++ * but clocksources won't necessarily get the needed notifications.
++ * For deeper system sleep states, this will be mandatory...
