Subject: [PATCH v2 0/7] include: add setbits32/clrbits32/clrsetbits32/setbits64/clrbits64/clrsetbits64
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 and the powerpc arch already have thoses pattern them as functions. (like ahci_sunxi.c or dwmac-meson8b)
The first patch rename some powerpc funtions for being consistent with
the new name convention.
The second patch adds the header with all setbits functions.
The third patch is a try to implement a coccinelle semantic patch to
find all place where xxxbits function could be used.
It should not be merged since it is un-finalized.
For the moment, the "add setbits.h header" is not working and need a future
coccinelle version.
The four last patch are example of some drivers convertion.
Thoses patchs give an example of the reduction of code won by using xxxbits32.
I would like to thanks Julia Lawall for her help on the coccinelle
patch.
Regards
Changes since v1:
- renamed LE functions to _leXX
- updated coccinnelle patch with JLawall's comments
