From 5d0efaf47ee90ac60efae790acee3a3ed99ebf80 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 10 Mar 2026 12:25:52 +0800 Subject: regulator: pca9450: Correct interrupt type Kernel warning on i.MX8MP-EVK when doing module test: irq: type mismatch, failed to map hwirq-3 for gpio@30200000! Per PCA945[X] specification: The IRQ_B pin is pulled low when any unmasked interrupt bit status is changed and it is released high once application processor read INT1 register. So the interrupt should be configured as IRQF_TRIGGER_LOW, not IRQF_TRIGGER_FALLING.

Introduce a type_name and set it per device type so the probed message matches the actual PMIC. While here, make the PCA9451A case explicit. No functional changes.
