net: phy: Add gmiitorgmii converter support

2019-10-08T07:41:27Z

This patch adds support for gmiitorgmii converter. This converter sits between the MAC and the external phy MAC <==> GMII2RGMII <==> RGMII_PHY. The ethernet driver probes this bridge and this bridge driver probes real phy driver and invokes the real phy functionalities as requested. This bridge just needs to be configured based on real phy negotiated speed and duplex. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek

net: phy: Define init routine and register generic phy driver

2019-10-08T07:41:27Z

This patch define init routine for generic phy driver and registers it using phy_register as this generic phy driver also needs to be relocated incase of manual reloc. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek

drivers: net: phy: Ignore PHY ID 0 during PHY probing

2019-07-18T21:37:13Z

Current code fails to probe some C45 PHYs that also respond to C22 reads. This is the case for PHYs like Aquantia AQR112, Marvell 88X2242 (as previously posted on the u-boot list). If the PHY ID reads all 0s just ignore it and try the next devad. Signed-off-by: Alex Marginean Reviewed-By: Ramon Fried Reviewed-by: Bin Meng Acked-by: Joe Hershberger

net: phy: Fix return value check phy_probe

2019-05-08T22:27:00Z

Don't ignore return value of phy_probe() call as the probe may fail and it needs to be reported. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek Acked-by: Joe Hershberger

net: phy: Reloc next and prev pointers inside phy_drivers

2019-05-08T22:27:00Z

This patch relocates the pointers inside phy_drivers incase of manual reloc. Without this reloc, these points to invalid pre relocation address and hence causes exception or hang. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek Acked-by: Joe Hershberger

net: phy: Add generic helpers to access MMD PHY registers

2019-05-07T19:51:55Z

Two new helper functions (phy_read_mmd() and phy_write_mmd()) are added to allow access to the MMD PHY registers. The MMD PHY registers can be accessed by several means: 1. Using two new MMD access function hooks in the PHY driver. These functions can be implemented when the PHY driver does not support the standard IEEE Compatible clause 45 access mechanism described in clause 22 or if the PHY uses its own non-standard access mechanism. 2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable DEVADs. 3. The standard clause 45 access extensions to the MMD registers through the indirection registers (clause 22) in all the other cases. Signed-off-by: Carlo Caione Acked-by: Joe Hershberger

net: phy: implement fallback mechanism for negative phy adresses

2019-04-08T00:31:16Z

Negative phy-addresses can occour if the caller function was not able to determine a valid phy address (from device-tree for example). In this case we catch this here and search for ANY phy device on the given mdio- bus. Signed-off-by: Hannes Schmelzer Tested-by: Michal Simek Tested-by: Lukasz Majewski

net: phy: Add clause 45 identifier to phy_device

2019-01-24T17:35:26Z

The phy devices can be accessed via clause 22 or via clause 45. This information can be deduced when we read phy id. if the phy id is read without giving any MDIO Manageable Device Address (MMD), then it conforms to clause 22. otherwise it conforms to clause 45.

net: phy: Move fixed link code to separate routine

2019-01-24T09:03:43Z

This patch moves fixed-link functionality code to a separate routine inorder to make it more modular and cleaner. Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek Acked-by: Joe Hershberger
