There's also the issue of documentation. Datasheets for embedded SoCs are
often not publicly available. Even when out-of-tree code exists, the lack of
documentation makes it more difficult to understand it and port it to
mainline. I've seen many such cases in practice for camera sensor drivers that
are often provided by vendors with a small set (or even a single) hardcoded
configurations, using large register address/value tables. Porting such a
driver to the mainline APIs often require computing register values from
parameters received through the subsystem API, which requires a good
understanding of the hardware.
