This series removes the cxl and cxlflash drivers for IBM CAPI devices. CAPI devices have been out of production for some time, and we're not aware of any remaining users who are likely to want a modern kernel. There's almost certainly some remaining driver bugs and we don't have much hardware available to properly test the drivers any more. Removing these drivers will also mean we can get rid of a non-trivial amount of support code in arch/powerpc. Thanks to everyone who's worked on these drivers over the last decade. This series does not affect the OpenCAPI/ocxl driver, nor does it affect Compute Express Link (the other cxl, an amusing but unfortunate naming collision). v1: https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=436014&state=* v1->v2: rebase and update docs Andrew Donnellan (2): cxlflash: Remove driver cxl: Remove driver .../ABI/{obsolete => removed}/sysfs-class-cxl | 55 +- Documentation/arch/powerpc/cxl.rst | 469 -- Documentation/arch/powerpc/cxlflash.rst | 433 -- Documentation/arch/powerpc/index.rst | 2 -
