2021-12-08dt-bindings: net: can: add support for Allwinner R40 CAN controllerEvgeny Boger1-0/+24
Allwinner R40 (also known as A40i, T3, V40) has a CAN controller. The controller is the same as in earlier A10 and A20 SoCs, but needs reset line to be deasserted before use. This patch Introduces new compatible for R40 CAN controller with required resets property.

2021-11-29dt-bindings: net: Add schema for Qualcomm BAM-DMUXStephan Gerhold1-0/+92
The BAM Data Multiplexer provides access to the network data channels of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or MSM8974. It is built using a simple protocol layer on top of a DMA engine (Qualcomm BAM) and bidirectional interrupts to coordinate power control. The device tree node combines the incoming interrupt with the outgoing interrupts (smem-states) as well as the two DMA channels, which allows the BAM-DMUX driver to request all necessary resources.

Used to define a local endpoint to communicate with MCTP peripherals attached to an I2C bus. This I2C endpoint can communicate with remote MCTP devices on the I2C bus. In the example I2C topology below (matching the second yaml example) we have MCTP devices on busses i2c1 and i2c6. MCTP-supporting busses are indicated by the 'mctp-controller' DT property on an I2C bus node. A mctp-i2c-controller I2C client DT node is placed at the top of the mux topology, since only the root I2C adapter will support I2C slave functionality. .-------. |eeprom | .------------. .------. /'-------' | adapter | | mux --@0,i2c5------' | i2c1 ----.*| --@1,i2c6--.--. |............| \'------' \ \ ......... | mctp-i2c- | \ \ \ .mctpB . | controller | \ \ '.0x30 . | | \ ......... \ '.......' | 0x50 | \ .mctpA . \ .........

Commit f546ff0c0c07 ("Move our minimum Sphinx version to 1.7") raised the minimum version to 1.7. For pdfdocs, sphinx_pre_install says: note: If you want pdf, you need at least Sphinx 2.4.4. , and current requirements.txt installs Sphinx 2.4.4. Update Sphinx versions mentioned in docs and remove a note on earlier Sphinx versions. Update zh_CN and it_IT translations as well.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux fixes from Paul Moore: "Unfortunately I need to request a revert for two LSM/SELinux patches that came in via the network tree. The two patches in question add a new SCTP/LSM hook as well as an SELinux implementation of that LSM hook. The short version of "why?" is in the commit description of the revert patch, but I'll copy-n-paste the important bits below to save some time for the curious: ... Unfortunately these two patches were merged without proper review (the Reviewed-by and Tested-by tags from Richard Haines were for previous revisions of these patches that were significantly different) and there are outstanding objections from the SELinux maintainers regarding these patches. Work is currently ongoing to correct the problems identified in the reverted patches, as well as others that have come up during review, but it is unclear at this point in time when that work will be ready for inclusion in the mainline kernel. In the interest of not keeping objectionable code in the kernel for multiple weeks, and potentially a kernel release, we are reverting the two problematic patches. As usual with these things there is plenty of context to go with this and I'll try to do my best to provide that now. This effort started with a report of SCTP client side peel-offs not working correctly with SELinux, Ondrej Mosnacek put forth a patch which he believed properly addressed the problem but upon review by the netdev folks Xin Long described some additional issues and submitted an improved patchset for review. The SELinux folks reviewed Xin Long's initial patchset and suggested some changes which resulted in a second patchset (v2) from Xin Long; this is the patchset that is currently in your tree. Unfortunately this v2 patchset from Xin Long was merged before it had spent even just 24 hours on the mailing lists during the early days of the merge window, a time when many of us were busy doing verification of the newly released v5.15 kernel as well final review and testing of our v5.16 pull requests. Making matters worse, upon reviewing the v2 patchset there were both changes which were found objectionable by SELinux standards as well as additional outstanding SCTP/SELinux interaction problems. At this point we did two things: resumed working on a better fix for the SCTP/SELinux issue(s) - thank you Ondrej - and we asked the networking folks to revert the v2 patchset. The revert request was obviously rejected, but at the time I believed it was just going to be an issue for linux-next; I wasn't expecting something this significant that was merged into the networking tree during the merge window to make it into your tree in the same window, yet as of last night that is exactly what happened. While we continue to try and resolve the SCTP/SELinux problem I am asking once again to revert the v2 patches and not ship the current security_sctp_assoc_established() hook in a v5.16-rcX kernel. If I was confident that we could solve these issues in a week, maybe two, I would refrain from asking for the revert but our current estimate is for a minimum of two weeks for the next patch revision. With the likelihood of additional delays due to normal patch review follow-up and/or holidays it seems to me that the safest course of action is to revert the patch both to try and keep some objectionable code out of a release kernel and limit the chances of any new breakages from such a change. While the SCTP/SELinux code in v5.15 and earlier has problems, they are known problems, and I'd like to try and avoid creating new and different problems while we work to fix things properly. One final thing to mention: Xin Long's v2 patchset consisted of four patches, yet this revert is for only the last two. We see the first two patches as good, reasonable, and not likely to cause an issue. In an attempt to create a cleaner revert patch we suggest leaving the first two patches in the tree as they are currently" * tag 'selinux-pr-20211112' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: net,lsm,selinux: revert the security_sctp_assoc_established() hook
