How is the device accessed with no registers?

Sorry, missed. dts use fsl,imx8qxp-mipi-cphy at 8qm, so I have not found it
by DTB_CHECK.

8ulp boudle other function's register.

csr_regs: csr@2dad0000 {
	compatible = "8upl-csr", "syscon", "simple-mfd";
        reg = <0x2dad0000 0x10000>;
        clocks = <&pcc5 IMX8ULP_CLK_CSI_REGS>;

        csr_regs_rst: reset-controller {
        	compatible = "nxp,imx8ulp-csr-regs-reset";
		...
        };

	mipi-phy {
		compatible = "fsl,imx8ulp-mipi-cphy";
		...
	};
};

I have not 8ulp to do test now and this serial are already quite big. I
plan update later.

Just put a fsl,imx8ulp-mipi-cphy here, because it is quite similar with
fsl,imx8qxp-mipi-cphy
