2020-07-16docs: networking: timestamping: add section for stacked PHC devicesVladimir Oltean1-0/+165
The concept of timestamping DSA switches / Ethernet PHYs is becoming more and more popular, however the Linux kernel timestamping code has evolved quite organically and there's layers upon layers of new and old code that need to work together for things to behave as expected. Add this chapter to explain what the overall goals are. Loosely based upon this email discussion plus some more info: https://lkml.org/lkml/2020/7/6/481 Signed-off-by: Vladimir Oltean <olteanv@gmail.com> Reviewed-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

There are no non-standard bindings being used. However Felix is a PCI device and Seville is a platform device. So give an example of device tree for this switch and document its compatible string.

2020-07-10ethtool: add tunnel info interfaceJakub Kicinski1-0/+33
Add an interface to report offloaded UDP ports via ethtool netlink. Now that core takes care of tracking which UDP tunnel ports the NICs are aware of we can quite easily export this information out to user space. The responsibility of writing the netlink dumps is split between ethtool code and udp_tunnel_nic.c - since udp_tunnel module may not always be loaded, yet we should always report the capabilities of the NIC. $ ethtool --show-tunnels eth0 Tunnel information for eth0: UDP port table 0: Size: 4 Types: vxlan No entries UDP port table 1: Size: 4 Types: geneve, vxlan-gpe Entries (1): port 1230, vxlan-gpe v4: - back to v2, build fix is now directly in udp_tunnel.h v3: - don't compile ETHTOOL_MSG_TUNNEL_INFO_GET in if CONFIG_INET not set. v2: - fix string set count, - reorder enums in the uAPI, - fix type of ETHTOOL_A_TUNNEL_UDP_TABLE_TYPES to bitset in docs and comments.

2020-07-10debugfs: make sure we can remove u32_array files cleanlyJakub Kicinski1-4/+8
debugfs_create_u32_array() allocates a small structure to wrap the data and size information about the array. If users ever try to remove the file this leads to a leak since nothing ever frees this wrapper. That said there are no upstream users of debugfs_create_u32_array() that'd remove a u32 array file (we only have one u32 array user in CMA), so there is no real bug here. Make callers pass a wrapper they allocated. This way the lifetime management of the wrapper is on the caller, and we can avoid the potential leak in debugfs.

Implement a managed variant of of_mdiobus_register(). We need to make mdio_devres into its own module because otherwise we'd hit circular sumbol dependencies between phylib and of_mdio.

2020-07-01net: phy: don't abuse devres in devm_mdiobus_register()Bartosz Golaszewski1-1/+0
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.

2020-06-30dt-bindings: copy process-schema-examples.yaml to process-schema.yamlMasahiro Yamada1-8/+20
There are two processed schema files: - processed-schema-examples.yaml Used for 'make dt_binding_check'. This is always a full schema. - processed-schema.yaml Used for 'make dtbs_check'. This may be a full schema, or a smaller subset if DT_SCHEMA_FILES is given by a user. If DT_SCHEMA_FILES is not specified, they are the same. You can copy the former to the latter instead of running dt-mk-schema twice. This saves the cpu time a lot when you do 'make dt_binding_check dtbs_check' because building the full schema takes a couple of seconds. If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated based on the specified yaml files.

2020-06-30dt-bindings: fix error in 'make clean' after 'make dt_binding_check'Masahiro Yamada1-0/+5
We are having more and more schema files. Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit calling dt-mk-schema") fixed the 'Argument list too long' error of the schema checks, but the same error happens while cleaning too. 'make clean' after 'make dt_binding_check' fails as follows: $ make dt_binding_check [ snip ] $ make clean make[2]: execvp: /bin/sh: Argument list too long make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127 make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2 make: *** [Makefile:1763: _clean_Documentation] Error 2 'make dt_binding_check' generates so many .example.dts, .dt.yaml files, which are passed to the 'rm' command when you run 'make clean'.
