[PATCH v1 0/2] regulator: pf9453: Fix IRQ trigger and allow sharing

[Franz Schnyder <fra.schnyder@gmail.com>]

From: Franz Schnyder <franz.schnyder@toradex.com>

The IRQ_B pin is an open-drain output. The datasheet specifies, that the
IRQ_B pin is pulled low when any unmasked interrupt bit status          
is changed, and it is released high once the application processor reads
the INT1 register. As it specifies a level-low behavior, it should not  
force a falling-edge interrupt.                                         
                                                                        
Remove the IRQF_TRIGGER_FALLING to not force the falling-edge interrupt 
and instead rely on the flag from the device tree.                      
Set the IRQF_SHARED to be able to share the interrupt line with         
other devices.
