2020-12-11extcon: fsa9480: Rewrite bindings in YAML and extendLinus Walleij2-21/+52
This rewrites the FSA9480 DT bindings using YAML and extends them with the compatible TI TSU6111. I chose to name the file fcs,fsa880 since this is the first switch, later versions are improvements.

2020-12-10dt-bindings: net: nfc: s3fwrn5: Change I2C interrupt trigger typeBongsu Jeon1-1/+1
Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING for stable NFC I2C interrupt handling. Samsung's NFC Firmware sends an i2c frame as below. 1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c frame to send. 2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the GPIO low. NFC driver's i2c interrupt handler would be called in the abnormal case as the NFC FW task of number 2 is delayed because of other high priority tasks. In that case, NFC driver will try to receive the i2c frame but there isn't any i2c frame to send in NFC. It would cause an I2C communication problem. This case would hardly happen. But, I changed the interrupt as a defense code. If Driver uses the TRIGGER_RISING instead of the LEVEL trigger, there would be no problem even if the NFC FW task is delayed.

2020-12-08docs: Update documentation to reflect what TAINT_CPU_OUT_OF_SPEC meansMathieu Chouquet-Stringer2-6/+19
Here's a patch updating the meaning of TAINT_CPU_OUT_OF_SPEC after Borislav introduced changes in a7e1f67ed29f and upcoming patches in tip. TAINT_CPU_OUT_OF_SPEC now means a bit more what it implies as the flag isn't set just because of a CPU misconfiguration or mismatch. Historically it was for SMP kernel oops on an officially SMP incapable processor but now it also covers CPUs whose MSRs have been incorrectly poked at from userspace, drivers being used on non supported architectures, broken firmware, mismatched CPUs, ...

2020-12-08docs: Add a new text describing how to report bugsThorsten Leemhuis2-0/+1632
Add a mostly finished document describing how to report issues with the Linux kernel to its developers. It is designed to be a lot more straight forward and easier to follow than the current text about this (Documentation/admin-guide/reporting-bugs.rst); at the same time the new text should be more helpful for people unfamiliar with the topic, as it provides a lot more details, too. The main work on the text is done, but some polishing is still needed. The text also needs to be reviewed by more people and a few issues still might need some discussion. To make these tasks easier, it was decided ([1]) to add this document to the kernel sources in parallel to the existing text; the latter will be removed once this text is considered good enough(tm). This document is quite long and provides a lot of details, but was carefully crafted to make sure it's can also serve people that are in a hurry. That's mainly achieved by having a TDLR and a step-by-step guide, which should be good enough for quite a lot of people. Everybody that wants or need more explanations can find them in a reference section, which describes all the needed steps in detail. Thanks to this structure the text can work for kernel developers that just need to look something up, experienced FLOSS contributors that are unfamiliar with the kernel's bug reporting workflow, and users reporting something upstream for the first time. The text is thus a bit like the kernel itself, which works well for embedded machines, a typical desktop PC, cloud servers, and HPC. The document was written in the hope it will improve the quality of the bug reports, especially those that come from people unfamiliar with how Linux kernel development works. Sadly quite a few reports from this group are currently of poor quality and/or get submitted to the wrong place. Part of the problem is the old reporting-bugs document, as it makes its essence hard to grasp; it's and also inaccurate and slightly outdated in a few spots. Due to this quite a few valid reports are ignored in the end, which is annoying for those that compiled them and bad for the kernel's quality. The document near the top points out that it's still unfinished, but nevertheless ready for consumption. Those few areas in the text that might need some further discussion contain a note pointing this out. Besides lack of review from core developers there is only one major issue left: the section 'Decode failure message' is known to be outdated: it's waiting for someone familiar with the topic to write something up or give at least provide some hints and pointers what to write there. The new document is dual-licensed under GPL-2.0+ or CC-BY-4.0. The latter is way more liberal and makes it attractive to use this text as a base when writing about this topic on websites or in books. This hopefully increases the chances that such texts are accurate and stick to official way of doing things.

git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux Saeed Mahameed says: ==================== mlx5-next auxbus support This pull request is targeting net-next and rdma-next branches. This series provides mlx5 support for auxiliary bus devices. It starts with a merge commit of tag 'auxbus-5.11-rc1' from gregkh/driver-core into mlx5-next, then the mlx5 patches that will convert mlx5 ulp devices (netdev, rdma, vdpa) to use the proper auxbus infrastructure instead of the internal mlx5 device and interface management implementation, which Leon is deleting at the end of this patchset.

2020-12-07media: doc: pixfmt-packed-yuv: Express 4:4:4 formats in a more compact wayLaurent Pinchart1-217/+56
The 4:4:4 packed YUV formats are documented with a bit-level representation, which creates a wide table. Switch to a byte-oriented representation to make it more compact. This prepares for the addition of formats with more than 8 bits per component, that would make the table way too wide.

The pixfmt-packed-yuv.rst file documents packed YUV 4:4:4 formats, but is titled generically as "Packed YUV formats". 4:2:2 and 4:1:1 packed YUV formats are documented in separate files, which can be confusing.

2020-12-07media: doc: pixfmt-rgb: Clarify naming scheme for RGB formatsLaurent Pinchart1-78/+177
The naming scheme for the RGB pixel formats has been developed organically, and isn't consistent between formats using less than 8 bits per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666 that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored in 3 or 4 bytes). For the latter category, the names use a components order convention that is the opposite of the first category, and the opposite of DRM pixel formats. This has led to lots of confusion in the past, and would really benefit from being explained more precisely. Do so, which also prepares for the addition of additional RGB pixels formats.
