[PATCH v2 0/9] gpio: ep93xx: fixes series patch

[Nikita Shubin <nikita.shubin@xxxxxxxxxxx>]

Series of patches to fix ep93xx gpio driver to make IRQ's working.

The following are fix patches (these are enough to get gpio-ep93xx
working with modern kernel):

[PATCH v2 1/9] gpio: ep93xx: fix BUG_ON port F usage
[PATCH v2 2/9] gpio: ep93xx: Fix single irqchip with multi
 gpiochips
[PATCH v2 3/9] gpio: ep93xx: Fix wrong irq numbers in port F

The following are cleanup and style patches:

[PATCH v2 4/9] gpio: ep93xx: drop to_irq binding
[PATCH v2 5/9] gpio: ep93xx: Fix typo s/hierarchial/hierarchical
[PATCH v2 6/9] gpio: ep93xx: refactor ep93xx_gpio_add_bank
[PATCH v2 7/9] gpio: ep93xx: separate IRQ's setup
[PATCH v2 8/9] gpio: ep93xx: refactor base IRQ number
[PATCH v2 9/9] gpio: ep93xx: replace bools with idx for IRQ ports

The futher work can be done by removing ep93xx_gpio_port function
and, maybe, ep93xx_gpio_update_int_params. But i think it's better 
to be done in conjunction with converting ep93xx to DT support.
