[PATCH v7 0/3] greybus: gpio: Switch to the gpio descriptor interface

by Nishad Kamdar

This patch series converts uses of the old GPIO API to the GPIO descriptor API. It also converts the GPIO driver to use the GPIO irqchip library GPIOLIB_IRQCHIP instead of repimplementing the same. Chnages in v7: - Combine the three patches together. Changes in v6: - Patchset now contains two patches as the patch 1 has been accepted. - Changes mentioned in individual patches of the set. Changes in v5: - Drop the patch which uses gpiochip_get_data() in place of gpio_chip_to_gb_gpio_controller() as of now. - This is because it currently breaks the driver, since gpiochip_add() sets the data pointer to NULL. Changes in v4: - Changes mentioned in individual patches of the set. Changes in v3: - Combines the latest versions of the three greybus patches together in a patch series.
