net: mdiobus: add reset-post-delay-us handling

2020-08-03T22:01:02Z

Load new "reset-post-delay-us" value from MDIO properties, and if configured to a greater then zero delay do a flexible sleeping delay after MDIO bus reset deassert. This allows devices to exit reset state before start bus communication. Signed-off-by: Bruno Thomsen Reviewed-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: Uninline PHY ethtool statistics operations

2020-07-08T19:39:05Z

Now that we have moved the PHY ethtool statistics to be dynamically registered, we no longer need to inline those for ethtool. This used to be done to avoid cross symbol referencing and allow ethtool to be decoupled from PHYLIB entirely. Signed-off-by: Florian Fainelli Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: Properly define genphy_c45_driver

2020-07-07T19:47:10Z

Avoid the W=1 warning that symbol 'genphy_c45_driver' was not declared. Should it be static? Declare it on the phy header file. Reviewed-by: Florian Fainelli Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: don't abuse devres in devm_mdiobus_register()

2020-06-30T22:57:34Z

We currently have two managed helpers for mdiobus - devm_mdiobus_alloc() and devm_mdiobus_register(). The idea behind devres is that the release callback releases whatever resource the devm function allocates. In the mdiobus case however there's no devres associated with the device by devm_mdiobus_register(). Instead the release callback for devm_mdiobus_alloc(): _devm_mdiobus_free() unregisters the device if it is marked as managed. This all seems wrong. The managed structure shouldn't need to know or care about whether it's managed or not - and this is the case now for struct mii_bus. The devres wrapper should be opaque to the managed resource. This changeset makes devm_mdiobus_alloc() and devm_mdiobus_register() conform to common devres standards: devm_mdiobus_alloc() allocates a devres structure and registers a callback that will call mdiobus_free(). __devm_mdiobus_register() allocated another devres and registers a callback that will unregister the bus.

phy: un-inline devm_mdiobus_register()

2020-06-30T22:57:34Z

Functions should only be static inline if they're very short. This devres helper is already over 10 lines and it will grow soon as we'll be improving upon its approach. Pull it into mdio_devres.c. Signed-off-by: Bartosz Golaszewski Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: Add a helper to return the index for of the internal delay

2020-06-25T23:05:21Z

Add a helper function that will return the index in the array for the passed in internal delay value. The helper requires the array, size and delay value. The helper will then return the index for the exact match or return the index for the index to the closest smaller value. Signed-off-by: Dan Murphy Signed-off-by: David S. Miller

net: phy: make phy_disable_interrupts() non-static

2020-06-24T21:52:49Z

We face an issue with rtl8211f, a pin is shared between INTB and PMEB, and the PHY Register Accessible Interrupt is enabled by default, so the INTB/PMEB pin is always active in polling mode case. As Heiner pointed out "I was thinking about calling phy_disable_interrupts() in phy_init_hw(), to have a defined init state as we don't know in which state the PHY is if the PHY driver is loaded. We shouldn't assume that it's the chip power-on defaults, BIOS or boot loader could have changed this. Or in case of dual-boot systems the other OS could leave the PHY in whatever state." Make phy_disable_interrupts() non-static so that it could be used in phy_init_hw() to have a defined init state. Suggested-by: Heiner Kallweit Signed-off-by: Jisheng Zhang Signed-off-by: David S.

net: phy: add support for a common probe between shared PHYs

2020-06-24T21:33:16Z

Shared PHYs (PHYs in the same hardware package) may have shared registers and their drivers would usually need to share information. There is currently a way to have a shared (part of the) init, by using phy_package_init_once(). This patch extends the logic to share parts of the probe to allow sharing the initialization of locks or resources retrieval.

net: phy: Allow mdio buses to auto-probe c45 devices

2020-06-24T03:35:15Z

The mdiobus_scan logic is currently hardcoded to only work with c22 devices. This works fairly well in most cases, but its possible that a c45 device doesn't respond despite being a standard phy. If the parent hardware is capable, it makes sense to scan for c22 devices before falling back to c45. As we want this to reflect the capabilities of the STA, lets add a field to the mii_bus structure to represent the capability. That way devices can opt into the extended scanning. Existing users should continue to default to c22 only scanning as long as they are zero'ing the structure before use.
