drm/msm/mdp5: no scaling support on RGBn pipes for 8x16

2016-11-02T14:49:43+00:00

Looks like cut/paste error from the other device cfgs (which do support
scaling on RGBn pipes).

drm/msm/mdp5: handle non-fullscreen base plane case

2016-11-02T14:49:33+00:00

If the bottom-most layer is not fullscreen, we need to use the BASE
mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT).  The
blend_setup() code pretty much handled this already, we just had to
figure this out in _atomic_check() and assign the stages appropriately.

Also fix the case where there are zero enabled planes, where we also
need to enable BORDER_OUT.

drm/msm/mdp5: Set rotation property initial value to DRM_ROTATE_0 insted of 0

2016-09-15T21:21:12+00:00

0 isn't a valid rotation property value, so let's set the initial value
of the property to DRM_ROTATE_0 instead.

In the same vein, we must always have at leat one angle as part of set
of supported rotation bits, so let's include DRM_ROTATE_0 in there.

drm/msm/mdp4: mark symbols static where possible

2016-09-15T21:21:11+00:00

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/msm/mdp/mdp4/mdp4_lcdc_encoder.c:96:23: warning: no previous prototype for 'get_connector' [-Wmissing-prototypes]
drivers/gpu/drm/msm/mdp/mdp4/mdp4_plane.c:84:5: warning: no previous prototype for 'mdp4_plane_set_property' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

drm/msm/mdp4: Fix issue with LCDC/LVDS port parsing

2016-09-15T16:53:37+00:00

The LVDS port is the first in the list of the output ports in MDP4.
The driver assumed that if the port and its corresponding endpoint
is defined, then there should be a panel node too. This isn't
necessary since boards may not really use a LVDS panel. Don't fail
if there isn't a panel node available.

While we're at it, use of_graph_get_endpoint_by_regs instead of
of_graph_get_next_endpoint to make it more explicit that the LVDS
output is at port 0.

drm: Allow drivers to modify plane_state in prepare_fb/cleanup_fb

2016-08-19T08:58:55+00:00

The drivers have to modify the atomic plane state during the prepare_fb
callback so they track allocations, reservations and dependencies for
this atomic operation involving this fb. In particular, how else do we
set the plane->fence from the framebuffer!

drm: BIT(DRM_ROTATE_?) -> DRM_ROTATE_?

2016-08-08T18:17:56+00:00

Only property creation uses the rotation as an index, so convert the
to figure the index when needed.

drm/msm: Delete unnecessary checks before drm_gem_object_unreference_unlocked()

2016-07-16T14:29:34+00:00

The drm_gem_object_unreference_unlocked() function tests whether
its argument is NULL and then returns immediately.
Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

drm/msm: Replace drm_fb_get_bpp_depth() with drm_format_plane_cpp()

2016-07-16T14:29:29+00:00

The driver needs the number of bytes per pixel, not the bpp and depth
info meant for fbdev compatibility. Use the right API.
