From e2414b289c2b68afab361def612ca3791cd70d12 Mon Sep 17 00:00:00 2001 From: "Christophe Leroy (CS GROUP)" Date: Thu, 30 Jul 2026 14:29:36 +0200 Subject: [PATCH] soc: fsl: qe: properly scan GPIO nodes at startup Before commit 156460811def ("soc: fsl: qe: Change GPIO driver to a proper platform driver") qe_add_gpiochips() was walking the device tree to find all nodes with compatible "fsl,mpc8323-qe-pario-bank". After that commit the discovery is handled by the platform core, therefore it is necessary to call of_platform_default_populate() on the par_io node.
