From eff68845b7e387974e5fc81ec8b5a0c9ad754106 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 9 Feb 2024 11:57:59 +0000 Subject: [PATCH] arm64: dts: allwinner: Transpeed 8K618-T: add WiFi nodes In contrast to other devices using Allwinner SoCs, the Transpeed 8K618-T TV box uses a mainline supported WiFi chip: it's Broadcom 4335 compatible, packaged by Murata. Add the required DT nodes to let DT users know about the SDIO device. There is an otherwise empty MMC device node, to receive the MAC address, that firmware might want to write in there.
