From 0ce4f0dbc2cb547077cbc903a53b4638ae0cac55 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 9 Aug 2006 14:16:41 -0700 Subject: sky2: phy power problem on 88e805x On the 88E805X chipsets (used in laptops), the PHY was not getting powered out of shutdown properly. The variable reg1 was getting reused incorrectly. This is probably the cause of the bug. http://bugzilla.kernel.org/show_bug.cgi?id=6471 Signed-off-by: Stephen Hemminger Signed-off-by: Greg Kroah-Hartman --- drivers/net/sky2.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/net/sky2.c b/drivers/net/sky2.c index a3cd0b37385..72ca553f8bc 100644 --- a/drivers/net/sky2.c +++ b/drivers/net/sky2.c @@ -233,6 +233,8 @@ static void sky2_set_power_state(struct sky2_hw *hw, pci_power_t state) if (hw->ports > 1) reg1 |= PCI_Y2_PHY2_COMA; } + sky2_pci_write32(hw, PCI_DEV_REG1, reg1); + udelay(100); if (hw->chip_id == CHIP_ID_YUKON_EC_U) { sky2_write16(hw, B0_CTST, Y2_HW_WOL_ON); @@ -243,8 +245,6 @@ static void sky2_set_power_state(struct sky2_hw *hw, pci_power_t state) sky2_pci_write32(hw, PCI_DEV_REG5, 0); } - sky2_pci_write32(hw, PCI_DEV_REG1, reg1); - break; case PCI_D3hot: -- cgit v1.2.3-18-g5258
