      drm/exynos: make wait_for_vblank a manager op · f74085a9
      由 Prathyush K 提交于 
      Changelog v2:
remove unnecessay wait_for_vblank call.
- with this patch, wait_for_vblank callback is moved from
  overlay ops to manager ops so it should be removed and
  it doesn't need to wait vblank signal at plane disable.

Changelog v1:
The wait_for_vblank callback is moved from overlay ops to manager ops
of exynos drm driver. Also, the check for DPMS OFF of encoder is
removed before calling wait_for_vblank.

      drm/exynos: make sure that overlay data are updated · 1daa892c
      由 Inki Dae 提交于 
      Changelog v2:
fix a little bit performance issue to previous patch.
- When drm framebuffer is destroyed, make sure that overlay
  data are updated to real hardwrae for all encoders
  instead of waiting for vblank every page flip request.
  For this, it adds a new function,
  exynos_drm_encoder_complete_scanout function.

Changelog v1:
This patch removes wait_for_vblank call from
exynos_drm_encoder_plane_disable function and move it to
exynos_drm_encoder_plane_commit function.

Disabling dma channel to each plane doens't need vblank
signal to update data to real hardware. But updating
overlay data to real hardware does need vblank signal.

      drm/exynos: fix display on issue · 44c91697
      由 Inki Dae 提交于 
      When crtc_funcs->dpms callback is called, exynos_crtc->dpms
and exynos_encoder->dpms are changed to new mode. But if user
requests dpms mode operation, OFF -> ON, when crtc's dpms callback
is called, exynos_encoder->dpms is also changed to ON. This
makes encoder's dpms callback call be ignored so display power
couldn't become on again.

This patch removes exynos_encoder->dpms changing and adds 'updated'
variable to exynos_drm_encoder structure to avoid duplicated overlay
updating.

      drm/exynos: fix display power call issue. · 58f6aad7
      由 Inki Dae 提交于 
      Changelog v3:
make exynos_drm_display_power function use exynos_drm_best_encoder
function instead of connector->encoder to get a valid encoder.
connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB
request, connector->encoder is NULL so fix this issue.

Changelog v2:
remove static prefix so that exynos_drm_best_encoder function
could be called by other modules.

Changelog v1:
this patch fixes the issue that display power callback isn't called.
with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL
so display_ops->power_on() wouldn't be called so this patch makes
exynos_drm_best_encoder function to be used to get a valid encoder
of each connector.

      drm/exynos: Disable plane when released · bcf4cef9
      由 Inki Dae 提交于 
      this patch ensures that each plane connected to encoder is disabled
when released, by adding disable callback function of encoder helper

we had faced with one issue that invalid memory is accessed by dma
once drm is released and then the dma is turned on again. actually,
in our case, page fault was incurred with iommu. the reason is that
a gem buffer accessed by the dma is also released once drm is released.

so this patch would fix this issue ensuring the dma is disabled
when released.

      drm/exynos: update crtc to plane safely · 1b85a071
      由 Inki Dae 提交于 
      if old_crtc isn't same as encoder->crtc then it means that
user changed crtc id to another one so a plane to old_crtc
should be disabled so that current plane can be updated safely
and plane->crtc should be set to new crtc(encoder->crtc)

      drm/exynos: fixed duplicated mode setting. · 50caf25c
      由 Inki Dae 提交于 
      this patch fixes that when drm_crtc_helper_set_mode() is called,
mode data for hardware overlay and conntroller are updated two times.
for example, in case that drm_crtc_helper_set_mode() is called,
overlay_ops->commit() and manager_ops->commit() callbacks can be called
two times, first at drm_crtc_helper_set_mode() and second
at drm_helper_connector_dpms().
