Subject: [PATCH] arm64: dts: rockchip: Enable the NPU on rk3588-rock-5-itx
Date: Tue, 14 Apr 2026 00:52:49 +0300	[thread overview]
Message-ID: <20260413215301.4656-1-stensilver@gmail.com> (raw)

This commit enables the NPU on Radxa Rock 5 ITX board.
The regulator vdd_npu_s0 was already in place and since the NPUs
power domain supply is now described remove the always-on property
from the regulator.
