Please use name for all fixed regulators which matches current format
recommendation: 'regulator-[0-9]+v[0-9]+'

Did you mean that vreg_sd_vdd should be updated according to the
suggested format because vreg_sd_vccb is not a fixed regulator?

Yeah, it should be about sd-vdd, but then this one should be named as
