> This patch series aims to add USB2.0 host support for the RZ/G3L SMARC EVK. The RZ/G3L USB PHY block is
> similar to RZ/G3S, but each port has an OTG controller, unlike RZ/G3S, which has an OTG controller only
> on port 1. This series migrates regulator driver to use id-table so there is hard dependency between
> reset driver and regulator driver.

>   Patch #5,#6,#7 - PHY subsystem

>  * Collected the tag for reset binding patch.

> v1->v2:

>  * Passing pointer to an array of regulators to make it scalable.
>  * Dropped regulator1-vbus and added a regulators group node.
>  * Updated commit description for patch#1,#4,#6,#7,#8,#9 and #10.
>  * Added enum instead of const in the compatible section.
>  * Updated schema check.
>  * Collected tag for PHY binding patch.
>    in the regulator driver.
>  * Added regulators group node and its children in SoC dtsi.
