2021-11-22Documentation: dmaengine: Correctly describe dmatest with channel unsetDaniel Thompson1-3/+4
Currently the documentation states that channels must be configured before running the dmatest. This has not been true since commit 6b41030fdc79 ("dmaengine: dmatest: Restore default for channel").

2021-11-22Documentation: dmaengine: Add a description of what dmatest doesDaniel Thompson1-0/+10
Currently it can difficult to determine what dmatest does without reading the source code. Let's add a description. The description is taken mostly from the patch header of commit 4a776f0aa922 ("dmatest: Simple DMA memcpy test client"). It has been edited and updated slightly. Nevertheless the new text was largely written by Haarvard Skinnemoen and was copied from another patch, already committed to the kernel, which has Haarvard's SoB: attached to it.

2021-11-22dt-bindings: pinctrl: uniphier: Add child node definitions to describe pin mux and configurationKunihiko Hayashi1-2/+36
In arch/arm/boot/dts/uniphier-pinctrl.dtsi, there are child nodes of pinctrl that defines pinmux and pincfg, however, there are no rules about that in dt-bindings. 'make dtbs_check' results an error with the following message: pinctrl: 'ain1', 'ain2', 'ainiec1', 'aout', 'aout1', 'aout2', ... ... 'usb2', 'usb3' do not match any of the regexes: 'pinctrl-[0-9]+' To avoid the issue, add the rules of pinmux and pincfg in each child node and grandchild node.

2021-11-17bpf, docs: Fix ordering of bpf documentationDave Tucker9-86/+80
This commit fixes the display of the BPF documentation in the sidebar when rendered as HTML. Before this patch, the sidebar would render as follows for some sections: | BPF Documentation |- BPF Type Format (BTF) |- BPF Type Format (BTF) This was due to creating a heading in index.rst followed by a sphinx toctree, where the file referenced carries the same title as the section heading. To fix this I applied a pattern that has been established in other subfolders of Documentation: 1. Re-wrote index.rst to have a single toctree 2. Split the sections out in to their own files Additionally maps.rst and programs.rst make use of a glob pattern to include map_* or prog_* rst files in their toctree, meaning future map or program type documentation will be automatically included.
