From d67ef24adf3c3fbaed62c31551d6e36f24fece16 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 13 Feb 2020 15:15:24 +0100 Subject: [PATCH] ARM: dts: Add devicetree for Integrator/AP with IM-PD1 This adds a device tree for the Integrator/AP with the IM-PD1 logic module mounted, using the new logic module bindings.
