Subject: [PATCH 2/2] arm64: dts: allwinner: Transpeed 8K618-T: add WiFi nodes
Date: Sun,  4 Feb 2024 10:32:55 +0100	[thread overview]
Message-ID: <20240204093255.148972-3-andre.przywara@arm.com> (raw)
In-Reply-To: <20240204093255.148972-1-andre.przywara@arm.com>

In contrast to other devices using Allwinner SoCs, the Transpeed 8K618-T
TV box uses a mainline supported WiFi chip: it's a Broadcom 4335
compatible, packaged by a company called Murata.
It works nicely with the Linux driver, when providing the respective
firmware files.

Add the required DT nodes to let the kernel find the SDIO device.
