[PATCH v2 1/4] arm64: dts: rockchip: use gated-fixed-clock for pcie-refclk on rk3588-jaguar

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner at cherry.de>

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.
