AFAIU, the power-source here should be 0, which selects VPH_PWR which is 3.3V. In that case I think we can avoid explicitly setting it. > > I'm not sure which one would be suitable here.

In that case I think we can avoid explicitly setting it. The firmware uses 1.8 V here in fact, but it seems like 3.3 V would work as well. > > I'm not sure which one would be suitable here.

Add the missing HID supplies to avoid relying on other consumers to keep them on. This also avoids the following warnings on boot: i2c_hid_of 0-0010: supply vdd not found, using dummy regulator i2c_hid_of 0-0010: supply vddl not found, using dummy regulator i2c_hid_of 1-0015: supply vdd not found, using dummy regulator i2c_hid_of 1-0015: supply vddl not found, using dummy regulator i2c_hid_of 1-003a: supply vdd not found, using dummy regulator i2c_hid_of 1-003a: supply vddl not found, using dummy regulator Note that VREG_MISC_3P3 is also used for things like the fingerprint reader which are not yet fully described so mark the regulator as always on for now.
