Subject: [PATCH 7/9] arm64: dts: allwinner: pinebook: Add GPIO port regulators
Date: Sun, 19 Jan 2020 10:31:02 -0600	[thread overview]
Message-ID: <20200119163104.13274-7-samuel@sholland.org> (raw)
In-Reply-To: <20200119163104.13274-1-samuel@sholland.org>

Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL.

VCC-PC and VCC-PG are supplied by ELDO1 at 1.8v.
VCC-PD is supplied by DCDC1 (VCC-IO) at 3.3v.
VCC-PE is supplied by ALDO1, and is unused.

VCC-PL creates a circular dependency, so it is omitted for now.
