From f27ed55359f6446541e8a3b926d7e13adf7e5950 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sun, 21 Jul 2024 13:49:31 +0200 Subject: [PATCH v3 11/14] arm64: dts: rockchip: define cpu-supply on the Qnap-TS433 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The TS433 seems to use a silergy,syr827 regulator for the cpu supply. At least that is the compatible used in the vendor devicetree, though it could very well also be another fan53555 clone. Define the needed regulator node and hook up the cpu-supply to the cpu cores.
