Subject: gpio: Move irq_default_type to struct gpio_irq_chip
X-Git-Tag: v5.15~10024^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3634eeb0fe9176e453c99834749dce21ea1305c1;p=platform%2Fkernel%2Flinux-starfive.git

gpio: Move irq_default_type to struct gpio_irq_chip

In order to consolidate the multiple ways to associate an IRQ chip with
a GPIO chip, move more fields into the new struct gpio_irq_chip.
