Not sure this change is correct. In phy-qcom-qmp driver, sm8350_usb3phy_cfg
has qmp_phy_vreg_l assignment.
static const char * const qmp_phy_vreg_l[] = {
"vdda-phy", "vdda-pll",
};
static const struct qmp_phy_cfg sm8350_usb3phy_cfg = {
.vreg_list = qmp_phy_vreg_l,
.num_vregs = ARRAY_SIZE(qmp_phy_vreg_l),
};
That means for "qcom,sm8350-qmp-usb3-phy" device, these two supplied are
required. The sony-xperia-sagami-pdx215 may work only because
devm_regulator_bulk_get() call in qcom_qmp_phy_vreg_init() doesn't fail
because of dummy regulator support.
