The implementation of each helper depends on the architecture, but they are all equivalent to regular I/O functions of similar names. So use regular functions instead and move all helpers into The first two patch are driver cleanups. Until now, contained an include of . As this will go away, patches 3 to 5 prepare include statements in the various drivers. Source files that use regular I/O helpers, such as readl(), now include . Source files that use framebuffer I/O helpers, such as fb_readl(), now include . Patch 6 replaces the architecture-based if-else branching in by helpers in . All helpers use Linux' existing I/O functions. Patch 7 harmonizes naming among fbdev and existing I/O functions. The patchset has been built for a variety of platforms, such as x86-64, arm, aarch64, ppc64, parisc, m64k, mips and sparc. v7: * fix hitfb build warnings (kernel test robot) v6: * fix build on 64-bit mips (kernel test robot) * update fb_io_fops.c v5: * fix build on s390 v4: * keep fb_mem*() as-is on ia64, loongarch, sparc64 (Arnd) * don't include (Sam) v3: * add the new helpers in * support reordering and native byte order (Geert, Arnd) v2: * use Linux I/O helpers (Sam, Arnd) Thomas Zimmermann (7): fbdev/hitfb: Cast I/O offset to address fbdev/matrox: Remove trailing whitespaces ipu-v3: Include fbdev: Include in various drivers fbdev: Include instead of fbdev: Move framebuffer I/O helpers into fbdev: Rename fb_mem*() helpers arch/ia64/include/asm/fb.h | 20 ++++ arch/loongarch/include/asm/fb.h | 21 ++++ arch/mips/include/asm/fb.h | 22 ++++ arch/parisc/video/fbdev.c | 3 +- arch/sparc/include/asm/fb.h | 20 ++++ arch/sparc/video/fbdev.c | 1 - arch/x86/video/fbdev.c | 2 - drivers/gpu/ipu-v3/ipu-prv.h | 1 + drivers/staging/sm750fb/sm750.c | 2 +- drivers/video/fbdev/arcfb.c | 1 + drivers/video/fbdev/aty/atyfb.h | 2 + drivers/video/fbdev/aty/mach64_cursor.c | 2 +- drivers/video/fbdev/chipsfb.c | 2 +- drivers/video/fbdev/core/fb_io_fops.c | 4 +- drivers/video/fbdev/core/fbcon.c | 1 - drivers/video/fbdev/core/fbmem.c | 2 - drivers/video/fbdev/hitfb.c | 122 +++++++++++--------- drivers/video/fbdev/kyro/fbdev.c | 2 +- drivers/video/fbdev/matrox/matroxfb_accel.c | 6 +- drivers/video/fbdev/matrox/matroxfb_base.h | 4 +- drivers/video/fbdev/pvr2fb.c | 2 +- drivers/video/fbdev/sstfb.c | 2 +- drivers/video/fbdev/stifb.c | 4 +- drivers/video/fbdev/tdfxfb.c | 2 +- drivers/video/fbdev/wmt_ge_rops.c | 2 + include/asm-generic/fb.h | 102 ++++++++++++++++ include/linux/fb.h | 55 +-------- 27 files changed, 279 insertions(+), 130 deletions(-)
