[PATCH v1 2/2] regulator: pf9453: Allow shared IRQ
From: Franz Schnyder
Date: Wed Feb 18 2026 - 05:38:16 EST
From: Franz Schnyder <franz.schnyder@xxxxxxxxxxx>
The PF9453 datasheet specifies the IRQ_B pin as an open drain output
with level-low behavior. This makes it capable to share the interrupt
line.
Set the IRQF_SHARED to be able to share the interrupt line with
other devices.
