net: phy: move at803x PHY driver to dedicated directory

2024-02-01T00:25:16+00:00

In preparation for addition of other Qcom PHY and to tidy things up, move the at803x PHY driver to dedicated directory. The same order in the Kconfig selection is saved.

net: phy: at803x: add LED support for qca808x

2024-01-27T05:03:31+00:00

Add LED support for QCA8081 PHY. Documentation for this LEDs PHY is very scarce even with NDA access to Documentation for OEMs. Only the blink pattern are documented and are very confusing most of the time. No documentation is present about forcing the LED on/off or to always blink. Those settings were reversed by poking the regs and trying to find the correct bits to trigger these modes. Some bits mode are not clear and maybe the documentation option are not 100% correct. For the sake of LED support the reversed option are enough to add support for current LED APIs. Supported HW control modes are: - tx - rx - link_10 - link_100 - link_1000 - link_2500 - half_duplex - full_duplex Also add support for LED polarity set to set LED polarity to active high or low. QSDK sets this value to high by default but PHY reset value doesn't have this enabled by default. QSDK also sets 2 additional bits but their usage is not clear, info about this is added in the header. It was verified that for correct function of the LED if active high is needed, only BIT 6 is needed.

net: phy: at803x: make read_status more generic

2024-01-07T16:23:22+00:00

Make read_status more generic in preparation on moving it to shared library as other PHY Family Driver will have the exact same implementation. The only specific part was a check for AR8031/33 if 1000basex was used. The check is moved to a dedicated function specific for those PHYs.

net: phy: at803x: add support for cdt cross short test for qca808x

2024-01-07T16:23:22+00:00

QCA808x PHY Family supports Cable Diagnostic Test also for Cross Pair Short. Add all the define to make enable and support these additional tests. Cross Short test was previously disabled by default, this is now changed and enabled by default. In this mode, the mask changed a bit and length is shifted based on the fault condition.

net: phy: at803x: refactor qca808x cable test get status function

2024-01-07T16:23:21+00:00

Refactor qca808x cable test get status function to remove code duplication and clean things up. The same logic is applied to each pair hence it can be generalized and moved to a common function. Signed-off-by: Christian Marangi Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: phy: add helpers to handle sfp phy connect/disconnect

2024-01-01T18:38:56+00:00

There are a few PHY drivers that can handle SFP modules through their sfp_upstream_ops. Introduce Phylib helpers to keep track of connected SFP PHYs in a netdevice's namespace, by adding the SFP PHY to the upstream PHY's netdev's namespace. By doing so, these SFP PHYs can be enumerated and exposed to users, which will be able to use their capabilities. Signed-off-by: Maxime Chevallier Signed-off-by: David S. Miller
