If there are braces for the "if", then there shall also be braces for
the "else" ("Use braces in both branches.")

Ditto. Please fix globally.

Indeed they should.  Why don't you autogenerate these, then?

We have all the tools in place, use them.

Why has this not been converted into a C struct?

Note: the following remark is a question, NOT a change request:

Would it not be possible to reduce all these terrible lists?  As far
as I can tell, the list is built sequentially, with both arguments to
_MXC_BUILD_NON_GPIO_PIN() being incremented by 4 for the next
register.  This begs for automatic code generation, doesn't it?

Mmmhh...checkpatch says:

total: 0 errors, 8 warnings, 2109 lines checked

0001-Add-support-for-MX35-processor.patch has style problems, please
review.  If any of these errors
are false positives report them to the maintainer, see

Warnings are only related to typedef ("do not add typedef"), so I do not
know where the errors are coming from. Do you use the --no-tree option
as I usually set?

checkpatch (and generally accepted in linux, as I can see) requires that
single statements must not be surrounded by braces. checkpatch returns a
warning, explaining that braces are not needed.

I see in the past some comments requiring to remove braces, but it you
prefer to add them. IMHO it is better to follow the same codestyle as
linux, using the same tools as checkpatch. I do not know why we have two
different results from checkpatch, I try to investigate. I had prefer to
use always braces in if statement, to avoid possible errors if some code
is added, but since checkpatch complains about it I was convinced to
remove them.

See my previous comment. I would prefer to not have a different rule in
u-boot, and not go against some provided tool (we use both checkpatch)
if not strictly required.

I will see how to use them.

I will check, I think I do not require anymore. NAND driver is in
mainline and does not require them. Probably I can remove them. In the
code I post now I do not use them at all, so probably I can remove them
without problems.

I do not know if it helps. The list follows exactly the description in
user manual, and, if you can see a rule for MX35_PIN_A*, it is not so
simply to find one for other pins, specially for the MXC_BUILD_GPIO_PIN.
At least, the list is at the moment coherent for all i.MX processors
(ok, ugly for all). The name of the pin cannot be generated, and it is
the name found in manual. Miore as generated, the list is sorted....

generate _NO_ warnings with checkpatch.


I feel that when the "single statement" is split across several lines,
