Subject: [PATCH 7/7] arm64: dts: realtek: Add RTD1395 and BPi-M4
Date: Mon, 11 Nov 2019 04:04:34 +0100 [thread overview]
Message-ID: <20191111030434.29977-8-afaerber@suse.de> (raw)
In-Reply-To: <20191111030434.29977-1-afaerber@suse.de>
Add Device Trees for Realtek RTD1395 SoC and Banana Pi BPi-M4 SBC.
For now reuse RTD1295 reset constants.
