+ - irq-gpios : GPIO specifier for the GPIO connected to /IRQ
The platform data this is providing is essentially a workaround for the
lack of an irq_to_gpio() function and the use of it is a workaround for
the lack of level triggered IRQ emulation in genirq... do we really
want this in the ABI (especially as a generic thing)?
Personally I would rather not add this to the DT unless we really
had to.
Also are you sure this is necessary on your system? Specifically
you only need this entry if the CODEC is connected to an IRQ line
that only supports edge triggered IRQs.
Mark, Charles, thanks for pointing me to this information.
I don't have this specific constraint on my system and could finally
also have it working using the regular interrupts / interrup-parent
properties.
So this new binding is not required for my case. I suppose we can forget
about it.
