Allwinner R329 SoC has two pin controllers similar to ones on previous
SoCs, one in CPUX power domain and another in CPUS.
This patch adds support for the CPUX domain pin controller.

No use of these.

Missed headers:

Thanks for these.
In addition, how to decide what header should be included? The code
works properly because of_device.h includes mod_devicetable.h.

The best approach is usually learnt with experience — the more you
code, the more you get. One of the rules is to avoid too many
inclusions and at the same time reduce indirect inclusions, so that
the headers which are guaranteed to be included by others shouldn't
appear. Another rule is that, for the headers (*.h files) the forward
declarations are preferable over the inclusion in case if the opaque
pointers are in use.

Forgot to put in the first place this:
The rule of thumb is Include headers that the header or C module is
direct user of. Additional information is located in the sections
below.
