2020-11-05gpiolib: fix sysfs when cdev is not selectedKent Gibson1-15/+0
In gpiochip_setup_dev() the call to gpiolib_cdev_register() indirectly calls device_add(). This is still required for the sysfs even when CONFIG_GPIO_CDEV is not selected in the build. Replace the stubbed functions in gpiolib-cdev.h with macros in gpiolib.c that perform the required device_add() and device_del() when CONFIG_GPIO_CDEV is not selected.

2020-10-08gpiolib: Update header block in gpiolib-cdev.hAndy Shevchenko1-1/+3
The dev_t is defined in types.h while struct gpio_device forward declaration is missed. Take into account above and update header block in gpiolib-cdev.h.

2020-09-30gpiolib: make cdev a build optionKent Gibson1-0/+15
Make the gpiolib-cdev module a build option. This allows the CDEV interface to be removed from the kernel to reduce kernel size in applications where is it not required, and provides the parent for other CDEV interface specific build options to follow.

2020-06-20gpiolib: split character device into gpiolib-cdevKent Gibson1-0/+11
Split the cdev specific functionality out of gpiolib.c and into gpiolib-cdev.c. This improves the readability and maintainability of both the cdev and core gpiolib code.
