net: mdio: Move MDIO drivers into a new subdirectory

2020-08-27T13:55:50+00:00

Move all the MDIO drivers and multiplexers into drivers/net/mdio. The mdio core is however left in the phy directory, due to mutual dependencies between the MDIO core and the PHY core. Take this opportunity to sort the Kconfig based on the menuconfig strings, and move the multiplexers to the end with a separating comment. v2: Fix typo in commit message Acked-by: Florian Fainelli Signed-off-by: Andrew Lunn Signed-off-by: David S.

net: phy: add a Kconfig option for mdio_devres

2020-07-07T22:37:02+00:00

If phylib is built as a module and CONFIG_MDIO_DEVICE is 'y', the mdio_device and mdio_bus code will be in the phylib module, not in the kernel image. Meanwhile we build mdio_devres depending on the CONFIG_MDIO_DEVICE symbol, so if it's 'y', it will go into the kernel and we'll hit the following linker error: ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_alloc_size': >> drivers/net/phy/mdio_devres.c:38: undefined reference to `mdiobus_alloc_size' ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_free': >> drivers/net/phy/mdio_devres.c:16: undefined reference to `mdiobus_free' ld: drivers/net/phy/mdio_devres.o: in function `__devm_mdiobus_register': >> drivers/net/phy/mdio_devres.c:87: undefined reference to `__mdiobus_register' ld: drivers/net/phy/mdio_devres.o: in function `devm_mdiobus_unregister': >> drivers/net/phy/mdio_devres.c:53: undefined reference to `mdiobus_unregister' ld: drivers/net/phy/mdio_devres.o: in function `devm_of_mdiobus_register': >> drivers/net/phy/mdio_devres.c:120: undefined reference to `of_mdiobus_register' Add a hidden Kconfig option for MDIO_DEVRES which will be currently selected by CONFIG_PHYLIB as there are no non-phylib users of these helpers.

net: phy: mscc: avoid skcipher API for single block AES encryption

2020-06-25T19:16:14+00:00

The skcipher API dynamically instantiates the transformation object on request that implements the requested algorithm optimally on the given platform. This notion of optimality only matters for cases like bulk network or disk encryption, where performance can be a bottleneck, or in cases where the algorithm itself is not known at compile time. In the mscc case, we are dealing with AES encryption of a single block, and so neither concern applies, and we are better off using the AES library interface, which is lightweight and safe for this kind of use. Note that the scatterlist API does not permit references to buffers that are located on the stack, so the existing code is incorrect in any case, but avoiding the skcipher and scatterlist APIs entirely is the most straight-forward approach to fixing this.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

net: phy: mscc-miim: read poll when high resolution timers are disabled

2020-05-26T22:33:56+00:00

The driver uses a read polling mechanism to check the status of the MDIO bus, to know if it is ready to accept next commands. This polling mechanism uses usleep_delay() under the hood between reads which is fine as long as high resolution timers are enabled. Otherwise the delays will end up to be much longer than expected. This patch fixes this by using udelay() under the hood when CONFIG_HIGH_RES_TIMERS isn't enabled. This increases CPU usage.
