Re: [PATCH] input: keyboard: gpio-keys: Try to parse IRQ from device tree

Hi Tomasz,

On modern platforms using device tree and non-legacy IRQ domains there
is usually no way to perform direct translation between GPIO and IRQ,
because the IRQ of interest is not mapped yet into sparse IRQ namespace.

This patch modifies the gpio_keys driver to parse IRQ from device tree
and use gpio_to_irq only as a fallback.

This means that this change would need to be applied to every driver
that currently maps gpio to IRQ. Why can't gpio_to_irq() be fixed
instead?

Thanks.
