1.There is a function in drm-core to calculate display timing parameters: horizontal front porch, back porch, sync length, vertical front porch, back porch, sync length and clock in Hz. However, some drivers are still calculating these parameters themselves. Therefore, there is a duplication of the code. This patch series replaces this redundant code with the function drm_display_mode_to_videomode. This removes nearly 100 redundant lines from the related drivers. 2.For some drivers (sun4i) the reverse helper drm_display_mode_from_videomode is used. 3.For some drivers it replaces arithmatic operators (*, /) with shifting operators (>>, <<). 4.For some drivers DRM_MODE_FLAG_* are replaced with DISPLAY_FLAGS_* flags. 5.These changes apply to following crtc and encoder drivers: atmel-hlcdc bridge-tc358767 exynos-dsi fsl-dcu gma500-mdfld_dsi_dpi hisilicon-kirin_dsi, ade meson-encoder pl111-display sun4i-tv ti lcdc tegra dc mediatek dpi dsi bridge-adv7533 Satendra Singh Thakur (13): drm/kms/mode/atmel-hlcdc: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/bridge-tc358767: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/exynos-dsi: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/fsl-dcu: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/gma500-mdfld_dsi_dpi: using helper function drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/hisilicon-kirin-dsi-ade: using helper function drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/meson-encoder: using helper function drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/pl111-display: using helper function drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/sun4i-tv: using helper func drm_display_mode_from_videomode for calculating timing parameters drm/kms/mode/ti-lcdc: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/tegra: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/mtk_dpi_dsi: using helper func drm_display_mode_to_videomode for calculating timing parameters drm/kms/mode/bridge-adv7533: using helper func drm_display_mode_to_videomode for calculating timing parameters drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c | 28 +++-- drivers/gpu/drm/bridge/adv7511/adv7533.c | 35 +++--- drivers/gpu/drm/bridge/tc358767.c | 42 +++---- drivers/gpu/drm/exynos/exynos_drm_dsi.c | 9 +- drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_crtc.c | 29 ++--- drivers/gpu/drm/gma500/mdfld_dsi_dpi.c | 28 ++--- drivers/gpu/drm/hisilicon/kirin/dw_drm_dsi.c | 42 ++++--- drivers/gpu/drm/hisilicon/kirin/kirin_drm_ade.c | 52 +++------ drivers/gpu/drm/mediatek/mtk_dpi.c | 60 +++++----- drivers/gpu/drm/mediatek/mtk_dsi.c | 14 +-- drivers/gpu/drm/meson/meson_venc.c | 149 +++++++++++------------- drivers/gpu/drm/pl111/pl111_display.c | 40 +++---- drivers/gpu/drm/sun4i/sun4i_tv.c | 67 ++++------- drivers/gpu/drm/tegra/dc.c | 15 ++- drivers/gpu/drm/tilcdc/tilcdc_crtc.c | 60 +++++----- 15 files changed, 280 insertions(+), 390 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
