drm exynos: use drm_fb_helper_set_par directly

2012-03-15T02:39:00+00:00

info->fix.visual already is correctly set from drm_fb_helper_fill_fix.
info->fix.line_length is also set from drm_fb_helper_fill_fix,
so drm_fb_helper_set_par directly instead of a custom
exynos_drm_fbdev_set_par.

drm/exynos: Fix fb_videomode <-> drm_mode_modeinfo conversion

2012-03-15T02:39:00+00:00

The fb_videomode structure stores the front porch and back porch in the
right_margin and left_margin fields respectively. right_margin should
thus be computed with hsync_start - hdisplay, and left_margin with
htotal - hsync_end. The same holds for the vertical direction.

       Region               Porch                           Porch

Fix the fb_videomode <-> drm_mode_modeinfo conversion functions
accordingly.

drm/exynos: fix runtime_pm fimd device state on probe

2012-03-15T02:38:59+00:00

A call to pm_runtime_set_active() forces device to be at the active
state and skips calling its runtime suspend/resume callbacks. This
results in a freeze with a new power domain code based on gen_pd. Fimd
driver does all required runtime power management calls, so this
pm_runtime_set_active call is buggy. This patch removes it and corrects
clock management in probe function (clocks are now enabled by
pm_runtime_get_sync() call).

drm/exynos: use correct 'exynos-drm' name for platform device

2012-03-15T02:38:59+00:00

Currently Exynos DRM driver uses DRIVER_NAME ('exynos') name for the
core platform device. This is confusing, because it doesn't refer to the
function the platform device is performing. This patch renames the
platform device to the 'exynos-drm', which matches the convention for
naming the platform devices. The name used inside DRM subsystem has not
been changed.

drm/exynos: removed pageflip_event_list init code when closed.

2012-02-15T01:29:11+00:00

if one process is terminated by ctrl-c while two processes are
using pageflip feature then for last pageflip event,
user can't get poll from kernel side so this patch fixes the problem.
