net: Kconfig: move the CAN device menu to the "Device Drivers" section

2022-06-11T15:11:02Z

The devices are meant to be under the "Device Drivers" category of the menuconfig. The CAN subsystem is currently one of the rare exception with all of its devices under the "Networking support" category. The CAN_DEV menuentry gets moved to fix this discrepancy. The CAN menu is added just before MCTP in order to be consistent with the current order under the "Networking support" menu. A dependency on CAN is added to CAN_DEV so that the CAN devices only show up if the CAN subsystem is enabled.

net: remove redundant 'depends on NET'

2021-01-28T01:04:12Z

These Kconfig files are included from net/Kconfig, inside the if NET ... endif. Remove 'depends on NET', which we know it is already met. Signed-off-by: Masahiro Yamada Link: https://lore.kernel.org/r/20210125232026.106855-1-masahiroy@kernel.org Signed-off-by: Jakub Kicinski

can: isotp: Explain PDU in CAN_ISOTP help text

2020-11-03T21:30:31Z

The help text for the CAN_ISOTP config symbol uses the acronym "PDU". However, this acronym is not explained here, nor in Documentation/networking/can.rst. Expand the acronym to make it easier for users to decide if they need to enable the CAN_ISOTP option or not.

As pointed out by Jakub Kicinski here: http://lore.kernel.org/r/20201009175751.5c54097f@kicinski-fedora-pc1c0hjn.dhcp.thefacebook.com this patch addresses the remarked issues: - remove empty line in comment - remove default=y for CAN_ISOTP in Kconfig - make use of pr_notice_once() - use GFP_ATOMIC instead of gfp_any() in soft hrtimer context The version strings in the CAN subsystem are removed by a separate patch.

can: add ISO 15765-2:2016 transport protocol

2020-10-07T21:18:33Z

CAN Transport Protocols offer support for segmented Point-to-Point communication between CAN nodes via two defined CAN Identifiers. As CAN frames can only transport a small amount of data bytes (max. 8 bytes for 'classic' CAN and max. 64 bytes for CAN FD) this segmentation is needed to transport longer PDUs as needed e.g. for vehicle diagnosis (UDS, ISO 14229) or IP-over-CAN traffic. This protocol driver implements data transfers according to ISO 15765-2:2016 for 'classic' CAN and CAN FD frame types.

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

2020-06-13T16:57:21Z

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

can: add support of SAE J1939 protocol

2019-09-04T12:22:33Z

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. J1939, ISO 11783 and NMEA 2000 all share the same high level protocol. SAE J1939 can be considered the replacement for the older SAE J1708 and SAE J1587 specifications.
