This supports -both copper and optical SFP modules, which require different Serdes -modes in order to properly negotiate the link. - -Optical SFP modules typically require the Serdes link to be talking -1000base-X mode - this is the gigabit ethernet mode defined by the -802.3 standard. - -Copper SFP modules typically integrate a PHY in the module to convert -from Serdes to copper, and the PHY will be configured by the vendor -to either present a 1000base-X Serdes link (for fixed 1000base-T) or -a SGMII Serdes link. However, this is vendor defined, so we instead -detect the PHY, switch the link to SGMII mode, and use traditional -PHY based negotiation. - -Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> - -- set port and port capability depending on connector type -- move autoneg mode setting to probe function -- set "supported" speed capabilities depending on reported ethernet - capabilities -- checks for short read -- dump eeprom base ID when checksum fails ---- - create mode 100644 drivers/net/phy/sfp.c - create mode 100644 include/linux/sfp.h - ---- a/drivers/net/phy/Kconfig -+++ b/drivers/net/phy/Kconfig -@@ -256,6 +256,11 @@ endif # RTL8366_SMI - - comment "MII PHY device drivers" - -+config SFP -+ tristate "SFP cage support" -+ depends on I2C && PHYLINK -+ select MDIO_I2C -+ - config AMD_PHY - tristate "AMD PHYs" - ---help--- ---- a/drivers/net/phy/Makefile -+++ b/drivers/net/phy/Makefile -@@ -41,6 +41,8 @@ obj-$(CONFIG_MDIO_SUN4I) += mdio-sun4i.o - obj-$(CONFIG_MDIO_THUNDER) += mdio-thunder.o - obj-$(CONFIG_MDIO_XGENE) += mdio-xgene.o - -+obj-$(CONFIG_SFP) += sfp.o -+ - obj-$(CONFIG_AMD_PHY) += amd.o - obj-$(CONFIG_AQUANTIA_PHY) += aquantia.o - obj-$(CONFIG_AT803X_PHY) += at803x.o ---- /dev/null -+++ b/drivers/net/phy/sfp.c -@@ -0,0 +1,1071 @@ -+#include <linux/delay.h> -+#include <linux/gpio.h> -+#include <linux/i2c.h> -+#include <linux/interrupt.h> -+#include <linux/jiffies.h> -+#include <linux/module.h> -+#include <linux/mutex.h> -+#include <linux/netdevice.h> -+#include <linux/of.h> -+#include <linux/of_net.h> -+#include <linux/phylink.h> -+#include <linux/platform_device.h> -+#include <linux/sfp.h> -+#include <linux/slab.h> -+#include <linux/workqueue.h> -+ -+#include "mdio-i2c.h" -+#include "swphy.h" -+ -+enum { -+ GPIO_MODDEF0, -+ GPIO_LOS, -+ GPIO_TX_FAULT, -+ GPIO_TX_DISABLE, -+ GPIO_RATE_SELECT, -+ GPIO_MAX, -+ -+ SFP_F_PRESENT = BIT(GPIO_MODDEF0), -+ SFP_F_LOS = BIT(GPIO_LOS), -+ SFP_F_TX_FAULT = BIT(GPIO_TX_FAULT), -+ SFP_F_TX_DISABLE = BIT(GPIO_TX_DISABLE), -+ SFP_F_RATE_SELECT = BIT(GPIO_RATE_SELECT), -+ -+ SFP_E_INSERT = 0, -+ SFP_E_REMOVE, -+ SFP_E_DEV_DOWN, -+ SFP_E_DEV_UP, -+ SFP_E_TX_FAULT, -+ SFP_E_TX_CLEAR, -+ SFP_E_LOS_HIGH, -+ SFP_E_LOS_LOW, -+ SFP_E_TIMEOUT, -+ -+ SFP_MOD_EMPTY = 0, -+ SFP_MOD_PROBE, -+ SFP_MOD_PRESENT, -+ SFP_MOD_ERROR, -+ -+ SFP_DEV_DOWN = 0, -+ SFP_DEV_UP, -+ -+ SFP_S_DOWN = 0, -+ SFP_S_INIT, -+ SFP_S_WAIT_LOS, -+ SFP_S_LINK_UP, -+ SFP_S_TX_FAULT, -+ SFP_S_REINIT, -+ SFP_S_TX_DISABLE, -+}; -+ -+static const char *gpio_of_names[] = { -+ "moddef0", -+ "los", -+ "tx-fault", -+ "tx-disable", -+ "rate-select", -+}; -+ -+static const enum gpiod_flags gpio_flags[] = { -+ GPIOD_IN, -+ GPIOD_IN, -+ GPIOD_IN, -+ GPIOD_ASIS, -+ GPIOD_ASIS, -+}; -+ -+#define T_INIT_JIFFIES msecs_to_jiffies(300) -+#define T_RESET_US 10 -+#define T_FAULT_RECOVER msecs_to_jiffies(1000) -+ -+/* SFP module presence detection is poor: the three MOD DEF signals are -+ * the same length on the PCB, which means it's possible for MOD DEF 0 to -+ * connect before the I2C bus on MOD DEF 1/2. -+ * -+ * The SFP MSA specifies 300ms as t_init (the time taken for TX_FAULT to -+ * be deasserted) but makes no mention of the earliest time before we can -+ * access the I2C EEPROM.
