From 06a6a774f6b8ed94aefcf60caa56fe92d3a18e17 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Sat, 9 Apr 2022 21:55:46 +0200 Subject: dt-bindings: gpio: realtek-otto: Add rtl9300 compatible Add the "realtek,rlt9300-gpio", "realtek,otto-gpio" compatible for GPIO nodes on the RTL930x SoC series. This SoC requires an extra register range, defining the interrupt CPU mapping registers.
