The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.
If GPIOLIB=n and asm-generic/gpio.h is not used:
drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_detect_cable’:
drivers/extcon/extcon-usb-gpio.c:63: error: implicit declaration of function ‘gpiod_get_value_cansleep’
drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_probe’:
drivers/extcon/extcon-usb-gpio.c:116: error: implicit declaration of function ‘devm_gpiod_get’
drivers/extcon/extcon-usb-gpio.c:116: warning: assignment makes pointer from integer without a cast
drivers/extcon/extcon-usb-gpio.c:122: error: implicit declaration of function ‘gpiod_set_debounce’
drivers/extcon/extcon-usb-gpio.c:129: error: implicit declaration of function ‘gpiod_to_irq’
Add the missing #include <linux/gpio/consumer.h> to fix this.

help
|
|
Say Y here to enable external connector class (extcon) support.
|
|
This allows monitoring external connectors by userspace
|
|
via sysfs and uevent and supports external connectors with
|
|
multiple states; i.e., an extcon that may have multiple
|
|
cables attached. For example, an external connector of a device
|
|
may be used to connect an HDMI cable and a AC adaptor, and to
|
|
host USB ports. Many of 30-pin connectors including PDMI are
|
|
also good examples.
