Subject: [PATCH 06/13] arm64: dts: mediatek: mt8192-asurada: Add CPU power supplies
Date: Fri, 20 Mar 2026 16:43:38 +0800	[thread overview]
Message-ID: <20260320084351.2461060-7-wenst@chromium.org> (raw)
In-Reply-To: <20260320084351.2461060-1-wenst@chromium.org>

The device tree for the MT8192 Asurada is missing power supplies for all
the CPU cores.

Add supplies to the CPU cores. The big and little clusters each have
their own regulator.
