From 38623d532c99ebd926f4eebb7c7de19cb7e5aef4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 22 Aug 2025 17:46:28 +0200 Subject: [PATCH] gpio: mmio: Add compatible for the ixp4xx eb MMIO The IXP4xx expansion bus can have simple memory-mapped GPIO on it. Using the proper device tree bindings, support probing this directly from the device tree.
