when the VIR_LDO1 regulator supplier is it's brother,
we can't find the supplier.
example code :
&vir_regulator {
ldo0_vir: ldo0-virtual {
regulator-compatible = "VIR_LDO0";
regulator-name= "VIR_LDO0";
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <2000000>;
};
ldo1_vir: ldo1-virtual {
regulator-compatible = "VIR_LDO1";
regulator-name= "VIR_LDO1";
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <3000000>;
ldo1-supply = <&ldo0_vir>;
};
...
}
so we add the child ptah to find the suppier.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
