Hello
This patchset adds a new set of functions which are open-coded in lot of
place.
Basicly the pattern is always the same, "read, modify a bit, write"
some driver already have thoses pattern them as functions. (like ahci_sunxi.c or dwmac-meson8b)
The first patch rename some powerpc funtions which already use the same name (xxxbits32)
but with only bigendian values.
The second patch adds the header.
The third patch is an ugly try to implement a coccinelle semantic patch to
find all place where xxxbits function could be used.
Probably this spatch could be better written and I didnt found an easy way to add the "linux/setbits" header.
The two last patch are example of convertion of two drivers.
Thoses patchs give an example of the reduction of code won by using xxxbits32.
This patchset is tested with the ahci_sunxi and dwmac-sun8i drivers.
Regards

Since setbits32/clrbits32 work on be32, it's better to remove ambiguity on
the used data type.

So now setbits32/clrbits32 is implicitly little-endian? Introducing new
implicit-endian accessors is probably a bad thing in general, but doing it
with a name that until this patchset was implicitly big-endian (at least on
powerpc) seems worse. Why not setbits32_le()?

What's the use case for setclrbits? I don't see it used anywhere in this
patchset (not even in the coccinelle patterns), it doesn't seem like it would
be a common pattern, and it could easily get confused with clrsetbits.

If you are going to do this, please add for_each_set_bit64() and similar.
For example, see:

Wouldn't it be better to call them setbits_be32() / clrbits_be32() to
have something looking similar to in_be32() / ou_be32() ?

So you changed the name of setbits32() ... to setbits32_be() and now you
are adding new functions called setbits32() ... which do something
different ?
What will happen if any file has been forgotten during the conversion,
or if anybody has outoftree drivers and missed this change ?
They will silently successfully compile without any error or warning,
and the result will be crap buggy.
And why would it be more legitim to have setbits32() be implicitely LE
instead of implicitely BE ?
I really think those new functions should be called something like
setbits_le32() ...

The same name as what ?

But the second patch adds functions with the same name as the powerpc
ones but doing something different. Why consider that setbits32() should
be LE and not BE ?

I believed that writel/readl was endian agnostic, but It seems that I was wrong.
So I will use _le32.

It is absent from the coccinelle script due to copy/paste error.
And absent from patchset since it is only two possible example that I can test.
If you run the next fixed coccinelle script, you will find some setclrbits.
Since I fear that mask and set could have some common bits sometimes, I prefer to keep separate clrsetbits and setclrbits.
