With commit c334bc1 (ARM: make mach/io.h include optional), PCMCIA was
broken. PCMCIA depends on __io() returning a valid i/o address, and most
ARM platforms require IO_SPACE_LIMIT be set to 0xffffffff for PCMCIA. This
needs a better fix with a fixed i/o address mapping, but for now we just
restore things to the previous behavior.
This fixes at91, omap1, pxa and sa11xx. pxa needs io.h if PCI is enabled,
but PCMCIA is not. sa11xx already has IO_SPACE_LIMIT set to 0xffffffff,
so it doesn't need an io.h.

Say Y if you want to enable SmartReflex.
|
|
|
|
SmartReflex can perform continuous dynamic voltage
|
|
scaling around the nominal operating point voltage
|
|
according to silicon characteristics and operating
|
|
conditions. Enabling SmartReflex reduces power
|
|
consumption.
|
|
|
|
Please note, that by default SmartReflex is only
|
|
initialized. To enable the automatic voltage
|
|
compensation for vdd mpu and vdd core from user space,
|
|
user must write 1 to
|
|
/debug/voltage/vdd_<X>/smartreflex/autocomp,
|
|
where X is mpu or core for OMAP3.
|
|
Optionally autocompensation can be enabled in the kernel
|
|
by default during system init via the enable_on_init flag
|
|
which an be passed as platform data to the smartreflex driver.

Say Y if you want to reset unused clocks during boot.

This option saves power, but assumes all drivers are

using the clock framework. Broken drivers that do not

yet use clock framework may not work with this option.
|
|
If you are booting from another operating system, you
|

probably do not want this option enabled until your

device drivers work properly.
