Josh Boyer 9c74360f9a staging: imx-drm: Fix modular build of DRM_IMX_IPUV3
commit b8d181e408 (staging: drm/imx: add drm plane support) added a file
to the make target for DRM_IMX_IPUV3 but didn't adjust the objs required
to actually build that as a module.  Kbuild got confused and this lead to
link errors like:

ERROR: "ipu_plane_disable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
ERROR: "ipu_plane_enable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!

Additionally, it added a call to imx_drm_crtc_id which also fails with a
link error as above.  To fix this, we adjust the make target with the proper
objs, which will change the name of the resulting .ko.  We also add an
EXPORT_SYMBOL_GPL for imx_drm_crtc_id.

Philipp Zabel b8d181e408 staging: drm/imx: add drm plane support
This patch adds support for a drm overlay plane on DI0 using the DP.
In principle, the overlay plane could also be used on DI1, but to switch
the overlay plane between display interfaces, the base planes would have
to be exchanged transparently while both display interfaces are inactive.

Sascha Hauer ac4c1a9b33 staging: drm/imx: Add LDB support
This adds support for the LVDS Display Bridge contained
in i.MX5 and i.MX6 SoCs.

Bit mapping, data width, and video timings are configurable
via device tree. Dual-channel mode is supported for a single
high-resolution source.

Philipp Zabel fcbc51e54d staging: drm/imx: Add support for Television Encoder (TVEv2)
This driver adds support for the Television Encoder integrated
on i.MX53 SoCs (TVEv2).

Currently only the VGA output mode is supported, which only uses
the TVDAC to generate RGB levels. HSYNC and VSYNC signals are
routed directly from the IPU signal generator pins through IOMUXC.

Sascha Hauer f326f7995b staging: drm/imx: Add i.MX IPUv3 crtc support
This adds a i.MX51/53/6 IPU (Image Processing Unit) KMS driver. The
driver has been tested on the i.MX51 babbage board, the i.MX53 LOCO
board and the i.MX6q sabrelite board in different clone mode and dual
head setups.

Sascha Hauer aecfbdb180 staging: drm/imx: add i.MX IPUv3 base driver
The IPU is the Image Processing Unit found on i.MX51/53/6 SoCs. It
features several units for image processing, this patch adds support
for the units needed for Framebuffer support, namely:

- Display Controller (dc)
- Display Interface (di)
- Display Multi Fifo Controller (dmfc)
- Display Processor (dp)
- Image DMA Controller (idmac)

This patch is based on the Freescale driver, but follows a different
approach. The Freescale code implements logical idmac channels and
the handling of the subunits is hidden in common idmac code pathes
in big switch/case statements. This patch instead just provides code
and resource management for the different subunits. The user, in this
case the framebuffer driver, decides how the different units play
together.

The IPU has other units missing in this patch:

- CMOS Sensor Interface (csi)
- Video Deinterlacer (vdi)
- Sensor Multi FIFO Controler (smfc)
- Image Converter (ic)
- Image Rotator (irt)

Sascha Hauer 19022aaae6 staging: drm/imx: Add parallel display support
This adds support for parallel displays for i.MX. It consists
of a drm encoder/connector pair which eventually passes EDID
data from the devicetree to the drm core.
