Configure PHY to appropriate mode depending on the -type of SFP inserted. On SFP removal configure PHY to the RGMII-copper -mode so RJ-45 port can still work. - -Signed-off-by: Ivan Bornyakov <i.bornyakov@metrotek.ru> -Link: https://lore.kernel.org/r/20210812134256.2436-1-i.bornyakov@metrotek.ru -Signed-off-by: Jakub Kicinski <kuba@kernel.org> ---- - drivers/net/phy/marvell.c | 105 +++++++++++++++++++++++++++++++++++++- - 1 file changed, 104 insertions(+), 1 deletion(-) - ---- a/drivers/net/phy/marvell.c -+++ b/drivers/net/phy/marvell.c -@@ -32,6 +32,7 @@ - #include <linux/marvell_phy.h> - #include <linux/bitfield.h> - #include <linux/of.h> -+#include <linux/sfp.h> - - #include <linux/io.h> - #include <asm/irq.h> -@@ -46,6 +47,7 @@ - #define MII_MARVELL_MISC_TEST_PAGE 0x06 - #define MII_MARVELL_VCT7_PAGE 0x07 - #define MII_MARVELL_WOL_PAGE 0x11 -+#define MII_MARVELL_MODE_PAGE 0x12 - - #define MII_M1011_IEVENT 0x13 - #define MII_M1011_IEVENT_CLEAR 0x0000 -@@ -162,7 +164,14 @@ - - #define MII_88E1510_GEN_CTRL_REG_1 0x14 - #define MII_88E1510_GEN_CTRL_REG_1_MODE_MASK 0x7 -+#define MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII 0x0 /* RGMII to copper */ - #define MII_88E1510_GEN_CTRL_REG_1_MODE_SGMII 0x1 /* SGMII to copper */ -+/* RGMII to 1000BASE-X */ -+#define MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_1000X 0x2 -+/* RGMII to 100BASE-FX */ -+#define MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_100FX 0x3 -+/* RGMII to SGMII */ -+#define MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_SGMII 0x4 - #define MII_88E1510_GEN_CTRL_REG_1_RESET 0x8000 /* Soft reset */ - - #define MII_VCT5_TX_RX_MDI0_COUPLING 0x10 -@@ -2505,6 +2514,100 @@ static int marvell_probe(struct phy_devi - return marvell_hwmon_probe(phydev); - } - -+static int m88e1510_sfp_insert(void *upstream, const struct sfp_eeprom_id *id) -+{ -+ struct phy_device *phydev = upstream; -+ phy_interface_t interface; -+ struct device *dev; -+ int oldpage; -+ int ret = 0; -+ u16 mode; -+ -+ __ETHTOOL_DECLARE_LINK_MODE_MASK(supported) = { 0, }; -+ -+ dev = &phydev->mdio.dev; -+ -+ sfp_parse_support(phydev->sfp_bus, id, supported); -+ interface = sfp_select_interface(phydev->sfp_bus, supported); -+ -+ dev_info(dev, "%s SFP module inserted\n", phy_modes(interface)); -+ -+ switch (interface) { -+ case PHY_INTERFACE_MODE_1000BASEX: -+ mode = MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_1000X; -+ -+ break; -+ case PHY_INTERFACE_MODE_100BASEX: -+ mode = MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_100FX; -+ -+ break; -+ case PHY_INTERFACE_MODE_SGMII: -+ mode = MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII_SGMII; -+ -+ break; -+ default: -+ dev_err(dev, "Incompatible SFP module inserted\n"); -+ -+ return -EINVAL; -+ } -+ -+ oldpage = phy_select_page(phydev, MII_MARVELL_MODE_PAGE); -+ if (oldpage < 0) -+ goto error; -+ -+ ret = __phy_modify(phydev, MII_88E1510_GEN_CTRL_REG_1, -+ MII_88E1510_GEN_CTRL_REG_1_MODE_MASK, mode); -+ if (ret < 0) -+ goto error; -+ -+ ret = __phy_set_bits(phydev, MII_88E1510_GEN_CTRL_REG_1, -+ MII_88E1510_GEN_CTRL_REG_1_RESET); -+ -+error: -+ return phy_restore_page(phydev, oldpage, ret); -+} -+ -+static void m88e1510_sfp_remove(void *upstream) -+{ -+ struct phy_device *phydev = upstream; -+ int oldpage; -+ int ret = 0; -+ -+ oldpage = phy_select_page(phydev, MII_MARVELL_MODE_PAGE); -+ if (oldpage < 0) -+ goto error; -+ -+ ret = __phy_modify(phydev, MII_88E1510_GEN_CTRL_REG_1, -+ MII_88E1510_GEN_CTRL_REG_1_MODE_MASK, -+ MII_88E1510_GEN_CTRL_REG_1_MODE_RGMII); -+ if (ret < 0) -+ goto error; -+ -+ ret = __phy_set_bits(phydev, MII_88E1510_GEN_CTRL_REG_1, -+ MII_88E1510_GEN_CTRL_REG_1_RESET); -+ -+error: -+ phy_restore_page(phydev, oldpage, ret); -+} -+ -+static const struct sfp_upstream_ops m88e1510_sfp_ops = { -+ .module_insert = m88e1510_sfp_insert, -+ .module_remove = m88e1510_sfp_remove, -+ .attach = phy_sfp_attach, -+ .detach = phy_sfp_detach, -+}; -+ -+static int m88e1510_probe(struct phy_device *phydev) -+{ -+ int err; -+ -+ err = marvell_probe(phydev); -+ if (err) -+ return err; -+ -+ return phy_sfp_probe(phydev, &m88e1510_sfp_ops); -+} -+ - static struct phy_driver marvell_drivers[] = { - { - .phy_id = MARVELL_PHY_ID_88E1101, -@@ -2711,7 +2814,7 @@ static struct phy_driver marvell_drivers - .driver_data = DEF_MARVELL_HWMON_OPS(m88e1510_hwmon_ops), - .features = PHY_GBIT_FIBRE_FEATURES, - .flags = PHY_POLL_CABLE_TEST, -- .probe = marvell_probe, -+ .probe = m88e1510_probe, - .config_init = m88e1510_config_init, - .config_aneg = m88e1510_config_aneg, - .read_status = marvell_read_status, |
