Subject: [PATCH] arm: dts: mediatek: mt6589: Add Arm Generic Timer node
Date: Wed, 25 Mar 2026 23:45:00 +0900 [thread overview]
Message-ID: <20260325144500.667385-1-akkun11.open@gmail.com> (raw)
Add the Arm Generic Timer node to the MT6589 SoC.
"arm,cpu-registers-not-fw-configured;" is required
because the bootloader does not initialize the Arm Generic Timer.
