Subject: [PATCH 03/14] arm64: dts: realtek: rtd139x: Introduce CRT, iso and misc syscon
Date: Mon, 2 Dec 2019 19:21:53 +0100 [thread overview]
Message-ID: <20191202182205.14629-4-afaerber@suse.de> (raw)
In-Reply-To: <20191202182205.14629-1-afaerber@suse.de>
Group the non-iso reset controller nodes into a CRT syscon mfd node.
Group reset controller, watchdog and UART0 into an Isolation mfd node.
Group UART1 and UART2 into a Miscellaneous syscon mfd node.
