Add an entry for erratum A011043: the MDIO_CFG[MDIO_RD_ER] bit may be falsely set when reading internal PCS registers. MDIO reads to internal PCS registers may result in having the MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and read data (MDIO_DATA[MDIO_DATA]) is correct. Software may get false read error when reading internal PCS registers through MDIO. As a workaround, all internal MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.

2020-01-17net: phy: Maintain MDIO device and bus statisticsFlorian Fainelli1-0/+63
We maintain global statistics for an entire MDIO bus, as well as broken down, per MDIO bus address statistics. Given that it is possible for MDIO devices such as switches to access MDIO bus addresses for which there is not a mdio_device instance created (therefore not a a corresponding device directory in sysfs either), we also maintain per-address statistics under the statistics folder. The layout looks like this: /sys/class/mdio_bus/../statistics/ transfers errrors writes reads transfers_<addr> errors_<addr> writes_<addr> reads_<addr> When a mdio_device instance is registered, a statistics/ folder is created with the tranfers, errors, writes and reads attributes which point to the appropriate MDIO bus statistics structure. Statistics are 64-bit unsigned quantities and maintained through the u64_stats_sync.h helper functions.

2020-01-10devlink: convert driver-specific files to reStructuredTextJacob Keller14-69/+221
Several drivers document what parameters they support in a devlink-params-*.txt file. This file is supposed to contain both the list of generic parameters implemented by the driver, as well as a list of driver-specific parameters and their descriptions. It would also be good if the driver documentation included other driver-specific implementations, such as info versions, devlink regions, and so forth. Convert all of these documentation files to reStructuredText, and rename them to just the driver name. Future changes will include other driver-specific implementations. Each file will contain a table for the generic parameters implemented, as well as a separate table for the driver-specific parameters. Future sections such as for devlink info versions will be added to these files. This avoids creating additional devlink-<feature>-<driver> files for each devlink feature, reducing clutter in the documentation folder.

2020-01-05net: phylink: add support for polling MAC PCSVladimir Oltean1-1/+2
Some MAC PCS blocks are unable to provide interrupts when their status changes. As we already have support in phylink for polling status, use this to provide a hook for MACs to enable polling mode. The patch idea was picked up from Russell King's suggestion on the macb phylink patch thread here [0] but the implementation was changed. Instead of introducing a new phylink_start_poll() function, which would make the implementation cumbersome for common PHYLINK implementations for multiple types of devices, like DSA, just add a boolean property to the phylink_config structure, which is just as backwards-compatible. https://lkml.org/lkml/2019/12/16/603 Suggested-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-01-05net: phy: add PHY_INTERFACE_MODE_10GBASERRussell King1-0/+18
Recent discussion has revealed that the use of PHY_INTERFACE_MODE_10GKR is incorrect. Add a 10GBASE-R definition, document both the -R and -KR versions, and the fact that 10GKR was used incorrectly.

2020-01-04Documentation: riscv: add patch acceptance guidelinesPaul Walmsley3-0/+37
Formalize, in kernel documentation, the patch acceptance policy for arch/riscv. In summary, it states that as maintainers, we plan to only accept patches for new modules or extensions that have been frozen or ratified by the RISC-V Foundation. We've been following these guidelines for the past few months. In the meantime, we've received quite a bit of feedback that it would be helpful to have these guidelines formally documented. Based on a suggestion from Matthew Wilcox, we also add a link to this file to Documentation/process/index.rst, to make this document easier to find. The format of this document has also been changed to align to the format outlined in the maintainer entry profiles, in accordance with comments from Jon Corbet and Dan Williams.

2020-01-04kcov: fix struct layout for kcov_remote_argAndrey Konovalov1-5/+5
Make the layout of kcov_remote_arg the same for 32-bit and 64-bit code. This makes it more convenient to write userspace apps that can be compiled into 32-bit or 64-bit binaries and still work with the same 64-bit kernel. Also use proper __u32 types in uapi headers instead of unsigned ints.
