depends on SYSFS
help
- Say Y here to add a sysfs interface for GPIOs.
+ Say Y here to add the legacy sysfs interface for GPIOs.
- This is mostly useful to work around omissions in a system's
- kernel support. Those are common in custom and semicustom
- hardware assembled using standard kernels with a minimum of
- custom patches. In those cases, userspace code may import
- a given GPIO from the kernel, if no kernel driver requested it.
-
- Kernel drivers may also request that a particular GPIO be
- exported to userspace; this can be useful when debugging.
+ This ABI is deprecated. If you want to use GPIO from userspace,
+ use the character device /dev/gpiochipN with the appropriate
+ ioctl() operations instead. The character device is always
+ available.

+ This driver supports internal booster (3V3) embedded in some
+ STMicroelectronics STM32 chips. It can be used to supply ADC analog
+ input switches when vdda supply is below 2.7V.
+
+ This driver can also be built as a module. If so, the module
+ will be called stm32-booster.
