Subject: [PATCH v6 1/2] regulator: dt-bindings: Add Allwinner D1 system LDOs
Date: Thu, 9 May 2024 23:31:06 +0800 [thread overview]
Message-ID: <20240509153107.438220-2-wens@kernel.org> (raw)
In-Reply-To: <20240509153107.438220-1-wens@kernel.org>
From: Samuel Holland <samuel@sholland.org>
The Allwinner D1 SoC contains two pairs of in-package LDOs. The pair of
"system" LDOs is for general purpose use. LDOA generally powers the
board's 1.8 V rail. LDOB powers the in-package DRAM, where applicable.
