From fd7a0ecf4e715c5f68a2a219fe774e1de730d0b7 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Tue, 19 Sep 2023 11:39:12 +0100 Subject: dt-bindings: mfd: x-powers,axp152: Make interrupt optional for more chips All X-Powers PMICs described by this binding have an IRQ pin, and so far (almost) all boards connected this to some NMI pin or GPIO on the SoC they are connected to. However we start to see boards that omit this connection, and technically the IRQ pin is not essential to the basic PMIC operation. The existing Linux driver allows skipping the IRQ pin setup for two chips already, so update the binding to also make the DT property optional for the missing chip. And while we are at it, add the AXP313a to that list, as they are actually boards out there not connecting the IRQ pin. This allows to have DTs correctly describing those boards not wiring up the interrupt.
