You don't need this. It should be selected and applied by the compatible
string matching.
Agreed, fix it in the next patch.

Make this a child of the below node and then you don't need this.
If there's a register address range associated with this, then add a reg
property.
Thanks for comments, I have defined herewith example
sysconf: chiptop@e0020000 {
compatible = "intel,syscon";
reg = <0xe0020000 0x100>;
emmc_phy: emmc_phy {
compatible = "intel,lgm-emmc-phy";
intel,syscon = <&sysconf>;
clocks = <&emmc>;
clock-names = "emmcclk";
#phy-cells = <0>;
};
};
Is this way need to add right?
+ clocks = <&sdxc>;
+ clock-names = "sdxcclk";
+ #phy-cells = <0>;
+ };

Nothing else in this h/w block? If there are other functions, then this
should not be in bindings/phy/.
Drop this one.

Needs to be more specific and reflect h/w blocks. 'syscon' is a Linux
thing to some extent.
Agreed, will drop it.
