[PATCH v2 6/7] gpio / ACPI: get rid of acpi_gpio.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that all users of acpi_gpio.h have been moved to user either the GPIO
descriptor interface or to the internal gpiolib.h we can get rid of
acpi_gpio.h entirely.

Once this is done the only interface to get GPIOs to drivers enumerated
from ACPI namespace is the descriptor based interface.
