Is this for the external phy? It doesn't seem like it from the board schematic I have... the regulator never makes it out of the black box that is the SIP/SOM if I'm reading right. My (poor) understanding was this was for the serdes phy that's doing the conversion to SGMII before hitting the board... good chance I'm wrong though. > > Signed-off-by: Bartosz Golaszewski > --- > drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c b/drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c > index 2f6b9b419601..21f329d2f7eb 100644 > --- a/drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c > +++ b/drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c > @@ -8,6 +8,7 @@ > #include > #include > #include > +#include > > #include "stmmac.h" > #include "stmmac_platform.h" > @@ -692,6 +693,10 @@ static int qcom_ethqos_probe(struct platform_device *pdev) > if (ret) > goto out_config_dt; > > + ret = devm_regulator_get_enable_optional(dev, "phy"); > + if (ret < 0 && ret != -ENODEV) > + goto out_config_dt; > + > ethqos->serdes_phy = devm_phy_optional_get(dev, "serdes"); > if (IS_ERR(ethqos->serdes_phy)) { > ret = PTR_ERR(ethqos->serdes_phy); > -- > 2.39.2 > _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
