Subject: [PATCH v2 4/4] arm64: dts: ti: sa67: set the GPU clock to 800MHz
Date: Tue, 23 Dec 2025 13:47:16 +0100 [thread overview]
Message-ID: <20251223124729.2482877-5-mwalle@kernel.org> (raw)
In-Reply-To: <20251223124729.2482877-1-mwalle@kernel.org>
The board is running with a core voltage of 0.85V and therefore we can
clock the GPU at 800MHz.
