The function should instead be generalized for any\nphy, at least as far as the ID registers are concerned. For the most\npart the read/write behaviour should be very similar across PHYs.\n\nThis patch renames tdk_{read,write,init}() to mdio_phy_*() so it can be\nused for any PHY.\n\nMore work definitely needs to be done here to make it easy to override\nthe default behaviour for specific PHYs, but this at least is a\nreasonable start.\n\nSigned-off-by: Grant Likely <grant.likely@arm.com>\nSigned-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>\n[PMD: just rebased]\n---\n include/hw/net/mdio.h | 2 +-\n hw/net/etraxfs_eth.c | 2 +-\n hw/net/mdio.c | 14 +++++++-------\n hw/net/xilinx_axienet.c | 2 +-\n 4 files changed, 10 insertions(+), 10 deletions(-)", "diff": "diff --git a/include/hw/net/mdio.h b/include/hw/net/mdio.h\nindex 7ffa4389b9..b3b4f497c0 100644\n--- a/include/hw/net/mdio.h\n+++ b/include/hw/net/mdio.h\n@@ -86,7 +86,7 @@ struct qemu_mdio {\n struct qemu_phy *devs[32];\n };\n \n-void tdk_init(struct qemu_phy *phy);\n+void mdio_phy_init(struct qemu_phy *phy, uint16_t id1, uint16_t id2);\n void mdio_attach(struct qemu_mdio *bus, struct qemu_phy *phy,\n unsigned int addr);\n uint16_t mdio_read_req(struct qemu_mdio *bus, uint8_t addr, uint8_t req);\ndiff --git a/hw/net/etraxfs_eth.c b/hw/net/etraxfs_eth.c\nindex f8d8f8441d..4c5415771f 100644\n--- a/hw/net/etraxfs_eth.c\n+++ b/hw/net/etraxfs_eth.c\n@@ -333,7 +333,7 @@ static int fs_eth_init(SysBusDevice *sbd)\n qemu_format_nic_info_str(qemu_get_queue(s->nic), s->conf.macaddr.a);\n \n \n- tdk_init(&s->phy);\n+ mdio_phy_init(&s->phy, 0x0300, 0xe400);\n mdio_attach(&s->mdio_bus, &s->phy, s->phyaddr);\n return 0;\n }\ndiff --git a/hw/net/mdio.c b/hw/net/mdio.c\nindex 3d70d99077..33bfbb4623 100644\n--- a/hw/net/mdio.c\n+++ b/hw/net/mdio.c\n@@ -43,7 +43,7 @@\n * linux driver (PHYID and Diagnostics reg).\n * TODO: Add friendly names for the register nums.\n */\n-static unsigned int tdk_read(struct qemu_phy *phy, unsigned int req)\n+static unsigned int mdio_phy_read(struct qemu_phy *phy, unsigned int req)\n {\n int regnum;\n unsigned r = 0;\n@@ -107,7 +107,7 @@ static unsigned int tdk_read(struct qemu_phy *phy, unsigned int req)\n return r;\n }\n \n-static void tdk_write(struct qemu_phy *phy, unsigned int req, unsigned int data)\n+static void mdio_phy_write(struct qemu_phy *phy, unsigned int req, unsigned int data)\n {\n int regnum;\n \n@@ -120,18 +120,18 @@ static void tdk_write(struct qemu_phy *phy, unsigned int req, unsigned int data)\n }\n }\n \n-void tdk_init(struct qemu_phy *phy)\n+void mdio_phy_init(struct qemu_phy *phy, uint16_t id1, uint16_t id2)\n {\n phy->regs[PHY_CTRL] = 0x3100;\n /* PHY Id. */\n- phy->regs[PHY_ID1] = 0x0300;\n- phy->regs[PHY_ID2] = 0xe400;\n+ phy->regs[PHY_ID1] = id1;\n+ phy->regs[PHY_ID2] = id2;\n /* Autonegotiation advertisement reg. */\n phy->regs[PHY_AUTONEG_ADV] = 0x01e1;\n phy->link = 1;\n \n- phy->read = tdk_read;\n- phy->write = tdk_write;\n+ phy->read = mdio_phy_read;\n+ phy->write = mdio_phy_write;\n }\n \n void mdio_attach(struct qemu_mdio *bus, struct qemu_phy *phy, unsigned int addr)\ndiff --git a/hw/net/xilinx_axienet.c b/hw/net/xilinx_axienet.c\nindex 1e859fdaae..408cd6e675 100644\n--- a/hw/net/xilinx_axienet.c\n+++ b/hw/net/xilinx_axienet.c\n@@ -791,7 +791,7 @@ static void xilinx_enet_realize(DeviceState *dev, Error **errp)\n object_get_typename(OBJECT(dev)), dev->id, s);\n qemu_format_nic_info_str(qemu_get_queue(s->nic), s->conf.macaddr.a);\n \n- tdk_init(&s->TEMAC.phy);\n+ mdio_phy_init(&s->TEMAC.phy, 0x0300, 0xe400);\n mdio_attach(&s->TEMAC.mdio_bus, &s->TEMAC.phy, s->c_phyaddr);\n \n s->TEMAC.parent = s;\n", "prefixes": [ "v5", "3/7" ] }
