In the schematics of document UM1907, the power supply for the micro SD card is the same 3v3 voltage that is used to power other devices on the board. By generalizing the name of the voltage regulator, it can be referenced by other nodes in the device tree without creating misunderstandings. This patch is preparatory for future developments.

This commit introduces Power over Data Line (PoDL) Power Source Equipment (PSE) regulator nodes to the PRTT1C devicetree. The addition of these nodes enables support for PoDL in PRTT1C devices, allowing power delivery and data transmission over a single twisted pair. The new PoDL PSE regulator nodes provide voltage capability information of the current board design, which can be used as a hint for system administrators when configuring and managing power settings. This update enhances the versatility and simplifies the power management of PRTT1C devices while ensuring compatibility with connected Powered Devices (PDs). After applying this patch, the power delivery can be controlled from user space with a patched [1] ethtool version using the following commands: ethtool --set-pse t1l2 podl-pse-admin-control enable to enable power delivery, and ethtool --show-pse t1l2 to display the PoDL PSE settings. By integrating PoDL PSE support into the PRTT1C devicetree, users can benefit from streamlined power and data connections in their deployments, improving overall system efficiency and reducing cabling complexity.

The revert commit 36a6418b ("Revert "ARM: dts: stm32: add CAN support on stm32f746"") prevented parsing errors due to the lack of CAN3 binding. Now that the binding definition for CAN3 is available in the mainline thanks to commit 8f3ef556 ("dt-bindings: mfd: stm32f7: Add binding definition for CAN3"), we can re-add the CAN support and make the driver usable again.

All boards using the DSI node duplicate the same pattern common pattern in board DTs, that pattern is ports with endpoint labels and the same in-SoC regulator connection. Move that common pattern into stm32mp157.dtsi instead. The two boards which do define panel@0 directly in the DSI bridge node now have #address-cells/#size-cells in their board DT instead of it being in stm32mp157.dtsi and activated incorrectly for all boards, even the ones which use e.g. another DSI-to-something bridge.

The Linux Automation Test Automation Controller (LXA TAC)[1] is an embedded software development tool built around the Octavo Systems OSD32MP15x SiP. The device contains an eMMC for storage, a DSA-capable on board ethernet switch with two external ports, dual CAN busses, a power switch to turn a device under test on or off and some other I/O. As of now there are two STM32MP157 based hardware generations (Gen 1 and Gen 2) that have most of their hardware config in common. In the future there will also be a STM32MP153 based hardware generation. [1]: https://www.linux-automation.com/en/products/lxa-tac.htmlSigned-off-by:

To be compatible with this configuration and the next OP-TEE versions, this patch removes in the STM32MP15 SCMI device tree the SHMEM used by OP-TEE SCMI and the associated reserved memory in the last 4KByte page of SRAM.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair. Repeats: 80e62bc8 ("MAINTAINERS: re-sort all entries and fields") Signed-off-by:

Suren Baghdasaryan authored
When forking a child process, the parent write-protects anonymous pages and COW-shares them with the child being forked using copy_present_pte(). We must not take any concurrent page faults on the source vma's as they are being processed, as we expect both the vma and the pte's behind it to be stable. For example, the anon_vma_fork() expects the parents vma->anon_vma to not change during the vma copy. A concurrent page fault on a page newly marked read-only by the page copy might trigger wp_page_copy() and a anon_vma_prepare(vma) on the source vma, defeating the anon_vma_clone() that wasn't done because the parent vma originally didn't have an anon_vma, but we now might end up copying a pte entry for a page that has one. Before the per-vma lock based changes, the mmap_lock guaranteed exclusion with concurrent page faults. But now we need to do a vma_start_write() to make sure no concurrent faults happen on this vma while it is being processed. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~5% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic.
