Improve the Kconfig help text of the follwing i2c drivers: * busses/i2c-pca-isa.c * chips/pcf8574.c * chips/pcf8591.c These are hard to detect and building them into the kernel results in long delays at boot.

DS1337 and DS1339 real-time clock chips.
|
|
|
|
This driver can also be built as a module. If so, the module

The ISP1301 is used in products including H2 and H3 development
|
|
boards for Texas Instruments OMAP processors.
|
|
|
|
This driver can also be built as a module. If so, the module

help
|
|
If you say yes here you get support for the Maxim MAX6875
|
|
EEPROM-programmable, quad power-supply sequencer/supervisor.
|
|
|
|
This provides an interface to program the EEPROM and reset the chip.
|
|
|
|
This driver also supports the Maxim MAX6874 hex power-supply
|
|
sequencer/supervisor if found at a compatible address.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called max6875.
