gpio: grgpio: Add device driver for GRGPIO cores
gpio: grgpio: Add irq support
.../devicetree/bindings/gpio/gpio-grgpio.txt | 26 +
drivers/gpio/Kconfig
The drivers sets up an irq domain and hands out unique irqs to irq
capable gpio lines regardless of how underlying irq maps to gpio
lines. Any gpio line can map to any one or none of the irqs of the
core, independently of each other.

Changes since v5
would be good
if of_gpiochip_reserve_irq_lines is just an empty dummy or something
like that when !defined(CONFIG_OF_IRQ).

the users of that function are fixed up to correctly handle a negative
return value.

For gpiolib-of.c, of_gpi
GPIO line should not be used for the given spi_device.
This sets the default value of cs_gpio in struct spi_device and entries
of cs_gpios in struct spi_master to -ENOENT. Thus, -ENOENT is the only
value used to indicate that no GPIO line should be used.

To be appl
used it is important that
failure to read a broken "cs-gpios" property does not silently fail
leading to the spi controller to use an unintended chipselect.

Just wonder, is it safe to pass null

Changes since v3:
- Add Reveiwed-by
- Fix pointed out style issues
- Use np->full_name directly instead of kstrdup'ing it as it is a const char*
- Call gpiochip_remove in grgpio_remove
