The Corsair digital power supplies of the series RMi, HXi and AXi include
a small micro-controller with a lot of sensors attached. The sensors can
be accessed by an USB connector from the outside.
This micro-controller provides the data by a simple proprietary USB HID
protocol. The data consist of temperatures, current and voltage levels,
power usage, uptimes, fan speed and some more. It is also possible to
configure the PSU (fan mode, mono/multi-rail, over current protection).
This driver provides access to the sensors/statistics of the RMi and HXi
series power supplies. It does not support configuring these devices,
because there would be many ways to misconfigure or even damage the PSU.

- hwmon driver corsair-psu
- hwmon documentation

Update bindings for the Dialog Semiconductor DA9121 voltage regulator to
add device variants.
Because several variants have multiple regulators, and to regard potential
to add GPIO support in future, the 'regulators' sub-node is added,
following the precedent set by other multi-regulator devices, including
the DA9211 family. This breaks compatibility with the original submission
by Vincent Whitchurch - but as this is still in for-next, the alignment
could be made before upstreaming occurs.

each C domain type/function declaration is put inside the namespace that

Add support for automatic cross-referencing inside C namespaces by
checking whether the corresponding source file had a C namespace Sphinx

This assumes there's only one namespace (if any) per rst file.
