Among the "static" instantiation methods the "board file" method is
described first. Move it as last, since it is being replaced by the other
methods.Also fix subsubsection heading syntax and remove the "Method 1[abc]"
prefix as the subsubsection structure clarifies the logical hierarchy.Signed-off-by: Luca Ceresoli

This section, partly dating back to the pre-git era, is somewhat
unclear and partly incorrect. Rewrite it almost completely including a
reference figure, concise but precise definition of each term and the
paths where drivers are found. Particular care has been put in clarifying
the relation between adapter and algorithm, which has no correspondence
in the I2C spec terminology.Signed-off-by: Luca Ceresoli

The justification of a light version of the parport driver was less
overhead for embedded systems. Well, today, even if an embedded system
still has a parport, it surely can handle the fully-fledged parport
driver. Remove it to reduce the maintenance burden.Signed-off-by: Wolfram Sang

Pull Documentation updates from Jonathan Corbet:
"Here are the main documentation changes for 5.5:- Various kerneldoc script enhancements.
- More RST conversions; those are slowing down as we run out of
things to convert, but we're a ways from done still.- Dan's "maintainer profile entry" work landed at last. Now we just
need to get maintainers to fill in the profiles...- A reworking of the parallel build setup to work better with a
variety of systems (and to not take over huge systems entirely in
particular).- The MAINTAINERS file is now converted to RST during the build.
Hopefully nobody ever tries to print this thing, or they will need
to load a lot of paper.- A script and documentation making it easy for maintainers to add
Link: tags at commit time.Also included is the removal of a bunch of spurious CR characters"

In the general move to have i2c_new_*_device functions which return
ERR_PTR instead of NULL, this patch converts i2c_new_probed_device().There are only few users, so this patch converts the I2C core and all
users in one go. The function gets renamed to i2c_new_scanned_device()
so out-of-tree users will get a build failure to understand they need to
adapt their error checking code.Signed-off-by: Wolfram Sang

* Mention disable_features flag 0x20.
* The i2c_ec driver has been removed from the kernel long ago. Driver
i2c-scmi serves the same purpose for more recent hardware.
