net: sfp: change quirks for Alcatel Lucent G-010S-P

2024-12-14T18:54:42+00:00

[ Upstream commit 90cb5f1776ba371478e2b08fbf7018c7bd781a8d ] Seems Alcatel Lucent G-010S-P also have the same problem that it uses TX_FAULT pin for SOC uart. So apply sfp_fixup_ignore_tx_fault to it.

net: phy: ti: add PHY_RST_AFTER_CLK_EN flag

2024-11-14T12:15:12+00:00

[ Upstream commit 256748d5480bb3c4b731236c6d6fc86a8e2815d8 ] DP83848 datasheet (section 4.7.2) indicates that the reset pin should be toggled after the clocks are running. Add the PHY_RST_AFTER_CLK_EN to make sure that this indication is respected. In my experience not having this flag enabled would lead to, on some boots, the wrong MII mode being selected if the PHY was initialized on the bootloader and was receiving data during Linux boot.

net: phy: dp83822: Fix reset pin definitions

2024-11-01T00:56:07+00:00

commit de96f6a3003513c796bbe4e23210a446913f5c00 upstream. This change fixes a rare issue where the PHY fails to detect a link due to incorrect reset behavior. The SW_RESET definition was incorrectly assigned to bit 14, which is the Digital Restart bit according to the datasheet. This commit corrects SW_RESET to bit 15 and assigns DIG_RESTART to bit 14 as per the datasheet specifications. The SW_RESET define is only used in the phy_reset function, which fully re-initializes the PHY after the reset is performed. The change in the bit definitions should not have any negative impact on the functionality of the PHY. v2: - added Fixes tag - improved commit message Cc: stable@vger.kernel.org Fixes: 5dc39fd5ef35 ("net: phy: DP83822: Add ability to advertise Fiber connection") Signed-off-by: Alex Michel Reviewed-by: Andrew Lunn Message-ID: Signed-off-by: Andrew Lunn Signed-off-by: Greg Kroah-Hartman

net: phy: dp83869: fix memory corruption when enabling fiber

2024-10-17T13:22:19+00:00

[ Upstream commit a842e443ca8184f2dc82ab307b43a8b38defd6a5 ] When configuring the fiber port, the DP83869 PHY driver incorrectly calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit number (10). This corrupts some other memory location -- in case of arm64 the priv pointer in the same structure. Since the advertising flags are updated from supported at the end of the function the incorrect line isn't needed at all and can be removed.
