2019-09-05habanalabs: rename user_ctx as compute_ctxOded Gabbay
This patch renames the "user_ctx" field in the device structure to "compute_ctx". This better reflects the meaning of this context. In addition, we also check in the ctx_fini() that the debug mode should be disabled only if the context being destroyed is the compute context. This has no effect right now as we only have a single process and a single context, but this makes the code more ready for multiple process support.

2019-09-05habanalabs: show the process context dram usageOded Gabbay
When the user query the dram usage of a context, show it the dram usage of its context, not the user context that is currently running on the device. This has no effect right now as we only have a single process and a single context, but this makes the code more ready for multiple process support.

2019-09-05habanalabs: kill user process after CS rollbackOded Gabbay
This patch calls the kill user process function after we rollback the in-flight CSs. This is because the user process can't be closed while there are open CSs. Therefore, there is no point of sending it a SIGKILL before we do the rollback CS part. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The ability of setting power management properties by the system administrator (through sysfs properties) is only relevant for the GOYA ASIC. Therefore, move the relevant sysfs properties to the GOYA sysfs specific file, to make the properties appear in sysfs only for GOYA cards.

2019-09-05habanalabs: cap simulator timeoutOded Gabbay
In the driver timeout functions, we give the simulator a factor of 10 in the timeout. This was necessary when the requested timeout is small but if it was a few seconds, this can result in a very large timeout which is unnecessary. This patch caps the maximum timeout of the simulator to 10 seconds, which is our largest timeout in the code. That is more then enough for anything the simulator is doing.

2019-09-05gianfar: use DT more consistently when selecting PHY connection typeArseny Solokha
Historically, gianfar only used phy-connection-type DT property when connected to PHY in the rgmii-id mode. It ignored the property otherwise, relying on the connection type auto-detection carried out by MAC and providing that reconstructed mode to of_phy_connect(). It also did not consider alternative phy-mode property at all. Make the driver properly query DT node for PHY connection type first and use an obtained value if it was specified there. Otherwise, if a particular DT relies on connection type auto-detection, fall back to reconstructing the value from MAC registers, as before.

They clean up the names of variables , structs and struct members, convert can_rx_register() to use max() instead of open coding it and remove unneeded code from the can_pernet_exit() callback. The next three patches are also by me and they introduce and make use of the CAN midlayer private structure. It is used to hold protocol specific per device data structures. The next patch is by Oleksij Rempel, switches the &net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that it can be used from NAPI (soft IRQ) context. The next 4 patches are by Kurt Van Dijck, he first updates his email address via mailmap and then extends sockaddr_can to include j1939 members. The final patch is the collective effort of many entities (The j1939 authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the CAN networking stack. SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world.
