arm64: dts: rockchip: use gated-fixed-clock for
From: Heiko Stuebner <heiko.stuebner@...> Date: Mon, 8 Jul 2024 01:01:52 +0200
Commit-Message
Using a combination of fixed clock and gpio-gate clock works but does not describe the actual hardware. Use the gated-fixed-clock binding to describe this in a nicer way. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
