TPS65910: IRQ: Add interrupt controller
This module controls the interrupt handling for the tps chip. The interrupt sources are the following: - GPIO falling/rising edge detection - Battery voltage below/above threshold - PWRON signal - PWRHOLD signal - Temperature detection - RTC alarm and periodic event Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk> Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
