From b1cc215d276855a0ec910e953e6b49cfe0721719 Mon Sep 17 00:00:00 2001 From: Sergey Ryazanov Date: Wed, 7 Jun 2017 01:49:37 +0300 Subject: [PATCH] ath25: 4.9: fix Ethernet tiny issues Few tiny fixes for issues caused by changes in the upstream: - do not touch PHY IRQ array (core code initializes it itself now) - add missed SET_NETDEV_DEV() invocation (causes segfault during phy connection) - use phy API inside the MDIO probe function instead of direct field access (consider phy structure changes in upstream and prevent similar issues in the future) Signed-off-by: Sergey Ryazanov --- .../patches-4.9/110-ar2313_ethernet.patch | 22 ++++++------------- 1 file changed, 7 insertions(+), 15 deletions(-) diff --git a/target/linux/ath25/patches-4.9/110-ar2313_ethernet.patch b/target/linux/ath25/patches-4.9/110-ar2313_ethernet.patch index 9b1286c075f1..ed3dcb491cf5 100644 --- a/target/linux/ath25/patches-4.9/110-ar2313_ethernet.patch +++ b/target/linux/ath25/patches-4.9/110-ar2313_ethernet.patch @@ -33,7 +33,7 @@ +obj-$(CONFIG_NET_AR231X) += ar231x.o --- /dev/null +++ b/drivers/net/ethernet/atheros/ar231x/ar231x.c -@@ -0,0 +1,1206 @@ +@@ -0,0 +1,1198 @@ +/* + * ar231x.c: Linux driver for the Atheros AR231x Ethernet device. + * @@ -221,6 +221,8 @@ + + platform_set_drvdata(pdev, dev); + ++ SET_NETDEV_DEV(dev, &pdev->dev); ++ + sp = netdev_priv(dev); + sp->dev = dev; + sp->cfg = pdev->dev.platform_data; @@ -304,8 +306,6 @@ + sp->mii_bus->reset = ar231x_mdiobus_reset; + sp->mii_bus->name = "ar231x_eth_mii"; + snprintf(sp->mii_bus->id, MII_BUS_ID_SIZE, "%d", pdev->id); -+ sp->mii_bus->irq = kmalloc(sizeof(int), GFP_KERNEL); -+ *sp->mii_bus->irq = PHY_POLL; + + mdiobus_register(sp->mii_bus); + @@ -1192,28 +1192,19 @@ +{ + struct ar231x_private *const sp = netdev_priv(dev); + struct phy_device *phydev = NULL; -+ int phy_addr; + + /* find the first (lowest address) PHY on the current MAC's MII bus */ -+ for (phy_addr = 0; phy_addr < PHY_MAX_ADDR; phy_addr++) -+ if (sp->mii_bus->phy_map[phy_addr]) { -+ phydev = sp->mii_bus->phy_map[phy_addr]; -+ sp->phy = phy_addr; -+ break; /* break out with first one found */ -+ } -+ ++ phydev = phy_find_first(sp->mii_bus); + if (!phydev) { + printk(KERN_ERR "ar231x: %s: no PHY found\n", dev->name); + return -1; + } + + /* now we are supposed to have a proper phydev, to attach to... */ -+ BUG_ON(!phydev); + BUG_ON(phydev->attached_dev); + -+ phydev = phy_connect(dev, dev_name(&phydev->dev), &ar231x_adjust_link, ++ phydev = phy_connect(dev, phydev_name(phydev), &ar231x_adjust_link, + PHY_INTERFACE_MODE_MII); -+ + if (IS_ERR(phydev)) { + printk(KERN_ERR "%s: Could not attach to PHY\n", dev->name); + return PTR_ERR(phydev); @@ -1233,9 +1224,10 @@ + + sp->oldduplex = -1; + sp->phy_dev = phydev; ++ sp->phy = phydev->mdio.addr; + + printk(KERN_INFO "%s: attached PHY driver [%s] (mii_bus:phy_addr=%s)\n", -+ dev->name, phydev->drv->name, dev_name(&phydev->dev)); ++ dev->name, phydev->drv->name, phydev_name(phydev)); + + return 0; +} -- 2.30.2
