- 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.
