Linus Walleij 8b29450437 gpio: siox: Use devm_ managed gpiochip
By using devm_gpiochip_add_data() we can get rid of the
remove() callback. As this driver doesn't use the
gpiochip data pointer we simply pass in NULL.

Linus Walleij b25e10f8f9 gpio: siox: Pass irqchip when adding gpiochip
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip.

For chained irqchips this is a pretty straight-forward
conversion.

Linus Walleij 8df9d7f70f gpio: siox: Switch to IRQ_TYPE_NONE
The siox driver is hardcoding a default type of
IRQ_TYPE_EDGE_RISING to the irq helper, but this should only
be applicable to old boardfiles and odd device tree irqchips
with just onecell irq (no flags). I doubt this is the case
with the siox, I think all consumers specify the flags they
use in the device tree.

Linus Walleij 4c0a8899d9 gpio: siox: Do not call gpiochip_remove() on errorpath
gpiochip_remove() was called on the errorpath if
gpiochip_add() failed: this is wrong, if the chip failed
to add it is not there so it should not be removed.

Uwe Kleine-König be8c8facc7 gpio: new driver to work with a 8x12 siox
This driver controls a SIOX device that provides 20 I/O lines. The first
twelve are fixed inputs, the remaining eight are outputs.
