From a764ff77d697a4a13e69b3379cc613f7409c6b9a Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Wed, 24 Nov 2021 09:17:13 +0200 Subject: regulator: irq_helper: Provide helper for trivial IRQ notifications Provide a generic map_event helper for regulators which have a notification IRQ with single, well defined purpose. Eg, IRQ always indicates exactly one event for exactly one regulator device. For such IRQs the mapping is trivial.
