(was: fbdev: Move framebuffer I/O helpers to <asm/fb.h>) Fbdev provides helpers for framebuffer I/O, such as fb_readl(), fb_writel() or fb_memcpy_to_fb(). The implementation of each helper depends on the architecture, but they all come down to regular I/O functions of similar names. So use the regular functions instead. The first patch a simple whitespace cleanup. Until now, <linux/fb.h> contained an include of <asm/io.h>. As this will go away patches 2 to 4 prepare include statements in the various drivers. Source files that use regular I/O helpers, such as readl(), now include <linux/io.h>. Source files that use framebuffer I/O helpers, such as fb_readl(), also include <linux/io.h>. Patch 5 replaces the architecture-based if-else branching in <linux/fb.h> by define statements that map to Linux' I/O fucntions. After this change has been merged and included in a few release without complains, we can update the drivers to regular I/O functions and remove the fbdev-specific defines. The patchset has been built for a variety of platforms, such as x86-64, arm, aarch64, ppc64, parisc, m64k, mips and sparc. v2: * use Linux I/O helpers (Sam, Arnd) Thomas Zimmermann (5): fbdev/matrox: Remove trailing whitespaces ipu-v3: Include <linux/io.h> fbdev: Include <linux/io.h> in various drivers fbdev: Include <linux/io.h> in drivers fbdev: Define framebuffer I/O from Linux' I/O functions drivers/gpu/ipu-v3/ipu-prv.h | 1 + drivers/video/fbdev/arcfb.c | 1 + drivers/video/fbdev/arkfb.c | 1 + drivers/video/fbdev/aty/atyfb.h | 2 + drivers/video/fbdev/aty/mach64_cursor.c | 3 +- drivers/video/fbdev/chipsfb.c | 1 + drivers/video/fbdev/cirrusfb.c | 1 + drivers/video/fbdev/core/cfbcopyarea.c | 2 +- drivers/video/fbdev/core/cfbfillrect.c | 2 + drivers/video/fbdev/core/cfbimgblt.c | 2 + drivers/video/fbdev/core/fbmem.c | 1 + drivers/video/fbdev/core/svgalib.c | 2 +- drivers/video/fbdev/hgafb.c | 2 +- drivers/video/fbdev/hitfb.c | 2 +- drivers/video/fbdev/kyro/fbdev.c | 2 +- drivers/video/fbdev/matrox/matroxfb_accel.c | 8 ++- drivers/video/fbdev/matrox/matroxfb_base.h | 6 +- drivers/video/fbdev/pm2fb.c | 1 + drivers/video/fbdev/pm3fb.c | 1 + drivers/video/fbdev/pvr2fb.c | 1 + drivers/video/fbdev/s3fb.c | 1 + drivers/video/fbdev/sstfb.c | 2 +- drivers/video/fbdev/tdfxfb.c | 2 +- drivers/video/fbdev/tridentfb.c | 1 + drivers/video/fbdev/vga16fb.c | 2 +- drivers/video/fbdev/vt8623fb.c | 1 + drivers/video/fbdev/wmt_ge_rops.c | 2 + include/linux/fb.h | 63 +++++---------------- 28 files changed, 52 insertions(+), 64 deletions(-) -- 2.40.0
