Subject: [PATCH 2/3] arm64: dts: rockchip: rk3399: rock960: Add 12V DCIN regulator
Date: Mon, 11 Mar 2019 20:33:31 +0530	[thread overview]
Message-ID: <20190311150332.19492-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190311150332.19492-1-jagan@amarulasolutions.com>

12V DCIN regulator is root source supply for the rest of regulators
in Rock960 power diagram.

Add support for it and attach same to supply vcc5v0_sys.
