arm64: dts: rockchip: use clock-generator for pcie-refclk
From: Heiko Stuebner <heiko@...> 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 new clock-generator binding to describe this in a nicer way. Signed-off-by: Heiko Stuebner <heiko@...>
