mfd: wm8994: Emulate level triggered interrupts if required
The interrupt controller on the wm8994 series of devices requires a level triggered parent. If one is not available but a GPIO is available for the interrupt then emulate. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
