drm/exynos: use drm generic mmap interface

2014-09-19T16:00:13+00:00

This patch removes DRM_EXYNOS_GEM_MMAP ictrl feature specific
to Exynos drm and instead uses drm generic mmap.

We had used the interface specific to Exynos drm to do mmap directly,
not to use demand paging which maps each page with physical memory
at page fault handler. We don't need the specific mmap interface
because the drm generic mmap which uses vm offset manager stuff can
also do mmap directly.

This patch makes a userspace region to be mapped with whole physical
memory region allocated by userspace request when mmap system call is
requested.

Changelog v2:
- do not set VM_IO, VM_DONTEXPEND and VM_DONTDUMP. These flags were already
  set by drm_gem_mmap
- do not include , which isn't needed anymore.

drm/exynos/ipp: remove struct exynos_drm_ipp_private

2014-08-03T07:52:17+00:00

struct exynos_drm_ipp_private contains only one pointer so all occurrences
of the struct can be replaced by the pointer itself.

drm/exynos: add TE handler to support LCD I80 interface

2014-08-03T07:52:15+00:00

To support LCD I80 interface, the panel should generate
Tearing Effect synchronization signal between MCU and FB
to display video images.
And the display controller should trigger to transfer
video image at this signal.
So the panel receives the TE IRQ, then calls these handler
chains to notify it to the display controller.

drm/exynos: change zero to NULL for sparse

2014-06-24T02:11:54+00:00

We recently changed this function to return a pointer instead of an int
so we need to change this zero to a NULL or Sparse complains:

drm: Don't export internal module variables

2014-06-18T11:50:16+00:00

Drivers really have no business touching these. Noticed because
exynose _did_ touch the vblank off delay, which could potentially
affect other drivers.

drm_debug is an exception since it's used in macros and inline
functions.

Note that this reduces the timeout on exynos from 50s to 5s.
Apparently this was done to paper over a vblank get/put race in
exynos, but really should be fixed properly somewhere else. Spotted by
David.

v2: Drop bonghits changes. Note to self: Don't submit patches
before first coffee.

drm/exynos: consider deferred probe case

2014-06-02T05:29:39+00:00

This patch makes sure that exynos drm framework handles deferred
probe case correctly.

Sub drivers could be probed before resources, clock, regulator,
phy or panel, are ready for them so we should make sure that exynos
drm core waits until all resources are ready and sub drivers are
probed correctly.

Chagelog v2:
- Make sure that exynos drm core tries to bind sub drivers only in case that
  they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:
  drm/exynos: mipi-dsi: consider panel driver-deferred probe
- Return error type correctly.

drm/exynos: add component framework support

2014-06-01T17:07:04+00:00

This patch adds component framework support to resolve
the probe order issue.

Until now, exynos drm had used codes specific to exynos drm
to resolve that issue so with this patch, the specific codes
are removed.
