Subject: arm64: dts: rockchip: Enable the NPU on Turing RK1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5360ad495b7bf1e3ea95f0e47961d5447a829f8e;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: rockchip: Enable the NPU on Turing RK1

Enable the NPU on Turing RK1.
The regulator vdd_npu_s0 was already in place; since
the NPU power domain supply is now described, remove the
regulator's always-on.
