This avoids the dependency on fbdev and makes the functionality available for non-fbdev code. Patch 1 replaces the variety of Kconfig options that control the Makefiles with CONFIG_VIDEO. More fine-grained control of the build can then be done within each video/ directory; see parisc for an example. Patch 2 replaces fb_is_primary_device() with video_is_primary_device(), which has no dependencies on fbdev. The implementation remains identical on all affected platforms. There's one minor change in fbcon, which is the only caller of fb_is_primary_device(). Patch 3 renames the source and header files from fbdev to video. v3: - arc, arm, arm64, sh, um: generate asm/video.h (Sam, Helge, Arnd) - fix typos (Sam) v2: - improve cover letter - rebase onto v6.9-rc1 Thomas Zimmermann (3): arch: Select fbdev helpers with CONFIG_VIDEO arch: Remove struct fb_info from video helpers arch: Rename fbdev header and source files arch/arc/include/asm/fb.h | 8 ------ arch/arm/include/asm/fb.h | 6 ----- arch/arm64/include/asm/fb.h | 10 -------- arch/loongarch/include/asm/{fb.h => video.h} | 8 +++--- arch/m68k/include/asm/{fb.h => video.h} | 8 +++--- arch/mips/include/asm/{fb.h => video.h} | 12 ++++----- arch/parisc/Makefile | 2 +- arch/parisc/include/asm/fb.h | 14 ----------- arch/parisc/include/asm/video.h | 16 ++++++++++++ arch/parisc/video/Makefile | 2 +- arch/parisc/video/{fbdev.c => video-sti.c} | 9 ++++--- arch/powerpc/include/asm/{fb.h => video.h} | 8 +++--- arch/powerpc/kernel/pci-common.c | 2 +- arch/sh/include/asm/fb.h | 7 ------ arch/sparc/Makefile | 4 +-- arch/sparc/include/asm/{fb.h => video.h} | 15 +++++------ arch/sparc/video/Makefile | 2 +- arch/sparc/video/fbdev.c | 26 -------------------- arch/sparc/video/video.c | 25 +++++++++++++++++++ arch/um/include/asm/Kbuild | 2 +- arch/x86/Makefile | 2 +- arch/x86/include/asm/fb.h | 19 -------------- arch/x86/include/asm/video.h | 21 ++++++++++++++++ arch/x86/video/Makefile | 3 ++- arch/x86/video/{fbdev.c => video.c} | 21 +++++++--------- drivers/video/fbdev/core/fbcon.c | 2 +- include/asm-generic/Kbuild | 2 +- include/asm-generic/{fb.h => video.h} | 17 +++++++------ include/linux/fb.h | 2 +- 29 files changed, 124 insertions(+), 151 deletions(-) delete mode 100644 arch/arc/include/asm/fb.h delete mode 100644 arch/arm/include/asm/fb.h delete mode 100644 arch/arm64/include/asm/fb.h rename arch/loongarch/include/asm/{fb.h => video.h} (86%) rename arch/m68k/include/asm/{fb.h => video.h} (86%) rename arch/mips/include/asm/{fb.h => video.h} (76%) delete mode 100644 arch/parisc/include/asm/fb.h create mode 100644 arch/parisc/include/asm/video.h rename arch/parisc/video/{fbdev.c => video-sti.c} (78%) rename arch/powerpc/include/asm/{fb.h => video.h} (76%) delete mode 100644 arch/sh/include/asm/fb.h rename arch/sparc/include/asm/{fb.h => video.h} (75%) delete mode 100644 arch/sparc/video/fbdev.c create mode 100644 arch/sparc/video/video.c delete mode 100644 arch/x86/include/asm/fb.h create mode 100644 arch/x86/include/asm/video.h rename arch/x86/video/{fbdev.c => video.c} (66%) rename include/asm-generic/{fb.h => video.h} (89%)
