The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> --- drivers/gpu/drm/aspeed/aspeed_gfx_crtc.c | 4 +- drivers/gpu/drm/drm_gem_atomic_helper.c | 96 +++++++++++++++++++- drivers/gpu/drm/drm_gem_framebuffer_helper.c | 63 ------------- drivers/gpu/drm/drm_gem_vram_helper.c | 4 +- drivers/gpu/drm/imx/dcss/dcss-plane.c | 4 +- drivers/gpu/drm/imx/ipuv3-plane.c | 4 +- drivers/gpu/drm/ingenic/ingenic-drm-drv.c | 3 +- drivers/gpu/drm/ingenic/ingenic-ipu.c | 4 +- drivers/gpu/drm/mcde/mcde_display.c | 4 +- drivers/gpu/drm/mediatek/mtk_drm_plane.c | 6 +- drivers/gpu/drm/meson/meson_overlay.c | 8 +- drivers/gpu/drm/meson/meson_plane.c | 4 +- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 4 +- drivers/gpu/drm/msm/msm_atomic.c | 4 +- drivers/gpu/drm/mxsfb/mxsfb_kms.c | 6 +- drivers/gpu/drm/pl111/pl111_display.c | 4 +- drivers/gpu/drm/rcar-du/rcar_du_vsp.c | 4 +- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 3 +- drivers/gpu/drm/stm/ltdc.c | 4 +- drivers/gpu/drm/sun4i/sun4i_layer.c | 4 +- drivers/gpu/drm/sun4i/sun8i_ui_layer.c | 4 +- drivers/gpu/drm/sun4i/sun8i_vi_layer.c | 4 +- drivers/gpu/drm/tegra/plane.c | 4 +- drivers/gpu/drm/tidss/tidss_plane.c | 4 +- drivers/gpu/drm/tiny/hx8357d.c | 4 +- drivers/gpu/drm/tiny/ili9225.c | 4 +- drivers/gpu/drm/tiny/ili9341.c | 4 +- drivers/gpu/drm/tiny/ili9486.c | 4 +- drivers/gpu/drm/tiny/mi0283qt.c | 4 +- drivers/gpu/drm/tiny/repaper.c | 3 +- drivers/gpu/drm/tiny/st7586.c | 4 +- drivers/gpu/drm/tiny/st7735r.c | 4 +- drivers/gpu/drm/tve200/tve200_display.c | 4 +- drivers/gpu/drm/vc4/vc4_plane.c | 4 +- drivers/gpu/drm/vkms/vkms_plane.c | 3 +- drivers/gpu/drm/xen/xen_drm_front_kms.c | 3 +- include/drm/drm_gem_atomic_helper.h | 8 ++ include/drm/drm_gem_framebuffer_helper.h | 6 +- include/drm/drm_modeset_helper_vtables.h | 2 +- include/drm/drm_plane.h | 4 +- include/drm/drm_simple_kms_helper.h | 2 +- 41 files changed, 178 insertions(+), 142 deletions(-) -- 2.30.0
