Subject: [PATCH] powerpc/44x: Use platform resource helper for GPIO MMIO
Date: Fri, 15 May 2026 16:25:14 -0700 [thread overview]
Message-ID: <20260515232514.1155590-1-rosenp@gmail.com> (raw)
Map the PPC4xx GPIO register block through the platform device
resource instead of reparsing the firmware node directly.
The GPIO node now probes as a platform device, so use the
platform helper to keep resource handling aligned with the converted
driver model and to report mapping failures with the platform device
context.
