Note that IGNORE is different from UNCONNECTED since setting UNCONNECTED type will disconnect the COMPHY in the COMPHY MUX which is a desired behaviour Signed-off-by: Yehuda Yitschak Signed-off-by: Stefan Roese Signed-off-by: Igal Liberman Reviewed-by: Stefan Roese --- diff --git a/drivers/phy/marvell/comphy_core.c b/drivers/phy/marvell/comphy_core.c index d8877e81e27..84f4e5f1895 100644 --- a/drivers/phy/marvell/comphy_core.c +++ b/drivers/phy/marvell/comphy_core.c @@ -37,7 +37,7 @@ static char *get_type_string(u32 type) "SGMII1", "SGMII2", "SGMII3", "QSGMII", "USB3_HOST0", "USB3_HOST1", "USB3_DEVICE", "XAUI0", "XAUI1", "XAUI2", "XAUI3", - "RXAUI0", "RXAUI1", "SFI"}; + "RXAUI0", "RXAUI1", "SFI", "IGNORE"}; if (type < 0 || type > PHY_TYPE_MAX) return "invalid"; diff --git a/drivers/phy/marvell/comphy_cp110.c b/drivers/phy/marvell/comphy_cp110.c index 8bec0abf75d..499aa683684 100644 --- a/drivers/phy/marvell/comphy_cp110.c +++ b/drivers/phy/marvell/comphy_cp110.c @@ -1663,6 +1663,7 @@ int comphy_cp110_init(struct chip_serdes_phy_config *ptr_chip_cfg, } switch (ptr_comphy_map->type) { case PHY_TYPE_UNCONNECTED: + case PHY_TYPE_IGNORE: continue; break; case PHY_TYPE_PEX0: diff --git a/drivers/phy/marvell/comphy_mux.c b/drivers/phy/marvell/comphy_mux.c index 1dc7426b638..b036fb13b9c 100644 --- a/drivers/phy/marvell/comphy_mux.c +++ b/drivers/phy/marvell/comphy_mux.c @@ -27,6 +27,10 @@ static void comphy_mux_check_config(struct comphy_mux_data *mux_data, for (lane = 0; lane < comphy_max_lanes; lane++, comphy_map_data++, mux_data++) { + /* Don't check ignored COMPHYs */ + if (comphy_map_data->type == PHY_TYPE_IGNORE) + continue; + mux_opt = mux_data->mux_values; for (opt = 0, valid = 0; opt < mux_data->max_lane_values; opt++, mux_opt++) { @@ -83,6 +87,9 @@ static void comphy_mux_reg_write(struct comphy_mux_data *mux_data, for (lane = 0; lane < comphy_max_lanes; lane++, comphy_map_data++, mux_data++) { + if (comphy_map_data->type == PHY_TYPE_IGNORE) + continue; + offset = lane * bitcount; mask = (((1 << bitcount) - 1) << offset); value = (comphy_mux_get_mux_value(mux_data, diff --git a/include/dt-bindings/comphy/comphy_data.h b/include/dt-bindings/comphy/comphy_data.h index d127388371b..5eb32ef6846 100644 --- a/include/dt-bindings/comphy/comphy_data.h +++ b/include/dt-bindings/comphy/comphy_data.h @@ -43,7 +43,8 @@ #define PHY_TYPE_RXAUI0 21 #define PHY_TYPE_RXAUI1 22 #define PHY_TYPE_SFI 23 -#define PHY_TYPE_MAX 24 +#define PHY_TYPE_IGNORE 24 +#define PHY_TYPE_MAX 25 #define PHY_TYPE_INVALID 0xff #define PHY_POLARITY_NO_INVERT 0
