I'm working on developing a driver for the max15301/15303 linear supply. I eventually want to push this upstream. The regulator driver for the supply has been created and loads properly. What I would like to do now is regression test the driver from userspace. I noticed that there are two different userspace drivers already present in the regulator framework. The first is the userpsace-consumer driver. The second is the virtual regulator driver. Both seem to create sysfs hooks for regulators. I have enabled the userspace-consumer and virtual driver in the kernel config. I can see that the modules are listed in the modules.builtin file. What seems to confuse me is how to bind the consumer driver to the regulator. Typically I would think this can be done in the device tree but the userspace-consumer driver doesn't support device tree. My question is, what is a good method to bind the userspace-consumer driver to the regulator under test? Would it be more appropriate to use the userspace-consumer driver or virtual driver? Thank you, Daniel
