Hi,

Question for rob+dt:

Given that a number of txt documents still are in need for YAML
conversion. Which is a bit beyond the author of this serie.
The core rk3568.dtsi is needed for other series to base on.

To speed things up a bit and reduce the work load:
Is it possible to add the grf compatibles in use first and do the rest
of the subnodes for various SoCs later?

Is it possible to add for now to reduce notification output:

additionalProperties: true

and then later:

additionalProperties: false

Example for rk3399:

	grf: syscon@...70000 {
		compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";

		io_domains: io-domains {
			compatible = "rockchip,rk3399-io-voltage-domain"; //
rockchip-io-domain.txt
		};

		mipi_dphy_rx0: mipi-dphy-rx0 {
			compatible = "rockchip,rk3399-mipi-dphy-rx0"; //
rockchip-mipi-dphy-rx0.yaml
		};

		u2phy0: usb2-phy@...0 {
			compatible = "rockchip,rk3399-usb2phy"; // phy-rockchip-inno-usb2.yaml
		};

		u2phy1: usb2-phy@...0 {
			compatible = "rockchip,rk3399-usb2phy"; // phy-rockchip-inno-usb2.yaml
		};

		emmc_phy: phy@...0 {
			compatible = "rockchip,rk3399-emmc-phy"; // rockchip-emmc-phy.txt
		};

		pcie_phy: pcie-phy {
			compatible = "rockchip,rk3399-pcie-phy"; // rockchip-pcie-phy.txt
		};
	};
