From 6d64bceb97a1c93b3cc2131f7e023ef2f9cf33f2 Mon Sep 17 00:00:00 2001 From: Nicolas Frattaroli Date: Mon, 21 Jul 2025 11:17:34 +0200 Subject: [PATCH] arm64: dts: rockchip: add pd_npu label for RK3588 power domains The NPU of the RK3588 has an external supply. This supply also affects the power domain of the NPU, not just the NPU device nodes themselves. Since correctly modelled boards will want the power domain to be aware of the regulator so that it doesn't always have to be on, add a label to the NPU power domain node so board files can reference it.
