From 2d85ecd6fb0eb2fee0ffa040ec1ddea57b09bc38 Mon Sep 17 00:00:00 2001 From: Franz Schnyder Date: Wed, 18 Feb 2026 11:25:14 +0100 Subject: [PATCH] regulator: pf9453: Respect IRQ trigger settings from firmware 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.
