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
