From 0a7565e53653f3e5a3448ef892b414187b8abba2 Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Fri, 31 Dec 2021 12:18:05 +0100 Subject: [PATCH] realtek: Update rtl839x.dtsi for realtek,rtl-intc, new gpio controller remove RTL8231 node Update the IRQ configuration to work with the new rtl-intc controller. Also change all KSEG1 addresses in reg = <> of the devics to physical addresses. Use the new gpio-otto controller instead of the legacy driver. Also remove the memory node as this is better put into a device .dts. Also remove the RTL8231 GPIO controller node from this base file since the chip might not be found in all Realtek RTL839x devices.
