    gpu: drm: omapdrm: dss-of: add missing of_node_put after calling of_parse_phandle

The of_get_next_parent will drop refcount on the passed node, so the reverted
patch is wrong, thanks for Tomi Valkeinen points it.

Merge remote-tracking branch 'airlied/drm-next' into topic/drm-misc

2016-07-19T07:27:29+00:00

Backmerge drm-next to be able to apply Chris' connector_unregister_all
cleanup (need latest i915 and sun4i state for that).

Also there's a trivial conflict in ttm_bo.c that git rerere fails to
remember.

of_node_put needs to be called when the device node which is got
from of_parse_phandle has finished using.

Linux 4.7-rc5

The fsl-dcu pull needs -rc3 so go to -rc5 for now.

drm/omapdrm: Workaround for errata i734 (LCD1 Gamma) in DSS dispc

2016-06-07T14:10:49+00:00

Workaround for errata i734 in DSS dispc
 - LCD1 Gamma Correction Is Not Working When GFX Pipe Is Disabled

For gamma tables to work on LCD1 the GFX plane has to be used at least
once after DSS HW has come out of reset. The workaround sets up a
minimal LCD setup with GFX plane and waits for one vertical sync irq
before disabling the setup and continuing with the context
restore. The physical outputs are gated during the operation.

For details see:
OMAP543x Multimedia Device Silicon Revision 2.0 Silicon Errata
Literature Number: SWPZ037E
Or some other relevant errata document for the DSS IP version.

drm/omapdrm: Add gamma table support to DSS dispc

2016-06-07T14:10:49+00:00

Add gamma table support to DSS dispc.

DSS driver initializes the default gamma table at component bind time
and holds a copy of all gamma tables in its internal data structure.

Each call to dispc_mgr_set_gamma() updates the internal table and
triggers write to the HW, if it is enabled. The tables are restored to
HW in PM resume callback. The drivers internal data structure match
the HW tables in size and in number of significant bits per color
component. The dispc_mgr_set_gamma() converts the size of any given
table for the internal data structure using linear interpolation.
Default gamma table is restored if NULL is given in place of gamma
lut.

dispc_mgr_gamma_size() gives HW gamma table size for the channel and
returns 0 if gamma table is not supported by the HW or the DSS driver.

Merge omapdss header refactoring

2016-06-07T09:42:58+00:00

Merge omapdss public header refactoring, which separates the public
header into omapdrm and omapfb parts.

Merge branch '4.8/omapdrm-pll' (omapdrm PLL work)

2016-06-06T07:16:51+00:00

Merge omapdrm PLL work, which makes it possible to use the DSS PLLs in a
versatile manner, for example, HDMI PLL can be used for LCDs.

drm/omap: Remove the video/omapdss.h and move it's content to local header file

2016-06-03T13:06:40+00:00

Move the contents of the video/omapdss.h header file to omapdrm/dss local
header file and remove the original global header. The omapfb stach is
using video/omapfb_dss.h so this change will complete the separation of the
two driver implementation.
