Subject: [PATCH 00/13] drm/kms/mode: using helper func
 drm_display_mode_to/from_videomode for calculating timing parameters

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
