Re: [PATCH 0/2][resend] gpio: pcf857x: enable gpio_to_irq()

[Kuninori Morimoto]

These patches add gpio_to_irq() support for gpio-pcf857x.

Kuninori Morimoto (2):
       gpio: pcf857x: share 8/16 bit access functions
       gpio: pcf857x: enable gpio_to_irq() support
 
I'm using pcf857x, and gpio_keys_polled driver, since pcf857x didn't support irq.
pcf857x has some pins, but interrupt is only 1 pin.
So, these patches add irq demux support on pcf857x driver,
and enabled gpio_to_irq().
Now, I can use both gpio_keys / gpio_keys_polled

These patches are based on latest linus/master branch
