The LDB driver changes the attached display interface's input clock mux
to the LDB_DI clock reference. Change it back again when disabling the
LVDS display. Changing back to the PLL5 for example allows to configure
the same DI for HDMI output later.

This patch allows to optionally attach the lvds-channel to a panel
supported by a drm_panel driver using of-graph bindings, instead of
supplying the modes via display-timings in the device tree.
This depends on of_graph_get_port_by_id and uses the OF graph to
link the optional DRM panel to the LDB lvds-channel. The output
port number is 1 on devices without the 4-port input multiplexer
(i.MX5) and 4 on devices with the mux (i.MX6).
Before:
ldb {
...
lvds-channel@0 {
...
display-timings {
native-timing = <&timing1>;
timing1: etm0700g0dh6 {
hactive = <800>;
vactive = <480>;
clock-frequency = <33260000>;
hsync-len = <128>;
hback-porch = <88>;
hfront-porch = <40>;
vsync-len = <2>;
vback-porch = <33>;
vfront-porch = <10>;
hsync-active = <0>;
vsync-active = <0>;
...
};
};
...
};
};
After:
ldb {
...
lvds-channel@0 {
...
port@4 {
reg = <4>;
lvds_out: endpoint {
remote_endpoint = <&panel_in>;
};
};
};
};
panel {
compatible = "edt,etm0700g0dh6", "simple-panel";
...
port {

This patch consolidates the different interface_pix_fmt, pixel_fmt, pix_fmt,
and pixfmt variables to a common name "bus_format" wherever they describe the
pixel format on the bus between display controller and encoder hardware.
At the same time, it renames imx_drm_panel_format to imx_drm_set_bus_format.

imx-drm internally misused the V4L2_PIX_FMT constants, which are supposed to
describe the pixel format of frame buffers in memory, to describe the pixel
format on the bus between the display controller and the encoder hardware.
Now that MEDIA_BUS_FMT constants are available to drm drivers, use those
instead.

for-next
Pull of-graph helpers from Philipp Zabel:
of: Add of-graph helpers to loop over endpoints and find ports by id
This series converts of_graph_get_next_endpoint to decrement the refcount of
the passed prev parameter. This allows to add a for_each_endpoint_of_node
helper macro to loop over all endpoints in a device tree node.
The of_graph_get_port_by_id function is added to retrieve a port by its known
port id (contained in the reg property) from the device tree.

Decrementing the reference count of the previous endpoint node allows to
use the of_graph_get_next_endpoint function in a for_each_... style macro.
All current users of this function that pass a non-NULL prev parameter
(that is, soc_camera and imx-drm) are changed to not decrement the passed
prev argument's refcount themselves.

After adding display power domain for Exynos5250 in commit
2d2c9a8d0a4f ("ARM: dts: add display power domain for exynos5250") the
display on Chromebook Snow and others stopped working after boot.
The reason for this suggested Andrzej Hajda: the DP clock was disabled.
This clock is required by Display Port and is enabled by bootloader.
However when FIMD driver probing was deferred, the display power domain
was turned off. This effectively reset the value of DP clock enable
register.
When exynos-dp is later probed, the clock is not enabled and display is
not properly configured:
exynos-dp 145b0000.dp-controller: Timeout of video streamclk ok
exynos-dp 145b0000.dp-controller: unable to config video

Because the helper function which calls this callback checks whether

So it would be better to remove the function for clarity.

While the VP (video processor) supports arbitrary scaling
of its input, the mixer just supports a simple 2x (line
doubling) scaling. Expose this functionality and exit
early when an unsupported scaling configuration is
encountered.
This was tested with modetest's DRM plane test (from
the libdrm test suite) on an Odroid-X2 (Exynos4412).

As for now there is no validation of incoming buffer
enqueue request as far as the gem buffers are being
concerned. This might lead to some undesired cases
when the driver tries to operate on invalid buffers
(wiht no valid gem object handle i.e.).
Add some basic checks to rule out those potential issues.

The goal of the change is to make sure we send the vblank event on the
current vblank. My hope is to fix any races that might be causing flicker.
After this change I only see a flicker in the transition plymouth and
X11.
Simplified the code by tracking vblank events on a per-crtc basis. This
allowed me to remove all error paths from the callback. It also allowed
me to remove the vblank wait from the callback.

The only extra operation on exynos_plane_destroy() was a call to
exynos_plane_disable() but the plane is already disabled by a earlier call
to drm_framebuffer_remove().

We already set each plane zpos at init, after that changes to zpos are
not expected. This patch turns zpos into a read-only property so now it is
impossible to set zpos.

Usually userspace don't want to have two overlay planes on the same zpos
so this change assign a different zpos for each plane. Before this change
a zpos of value zero was created for all planes so the userspace had to
set up the zpos of every plane it wanted to use.
Also all places that were storing zpos positions are now unsigned int.

struct {fimd,mixer,vidi}_win_data was just keeping the same data
as struct exynos_drm_plane thus get ride of it and use exynos_drm_plane
directly.
It changes how planes are created and remove .win_mode_set() callback
that was only filling all *_win_data structs.

XR24 planes were not shown properly, so now set the right registers
to correctly enable displaying these planes.
It also moves the alpha register settings to fimd_win_set_pixfmt()
to keep all pixel format stuff together.

The legcy colorkey ioctls are only implemented for sprite planes, so
reject the ioctl for primary/cursor planes. If we want to support
colorkeying with these planes (assuming we have hw support of course)
we should just move ahead with the colorkey property conversion.

Here's a single drm core fix, cc: stable, that affects i915
users.
* tag 'topic/drm-fixes-2015-04-02' of git://anongit.freedesktop.org/drm-intel:
drm/edid: set ELD for firmware and debugfs override EDIDs

| | | | | | | | |
| | | | | | | | |
| | | | | | | | | |
If the user supplies EDID through firmware or debugfs override, the
driver callbacks are bypassed and the connector ELD does not get
updated, and audio fails. Set ELD for firmware and debugfs EDIDs too.
There should be no harm in gratuitously doing this for non HDMI/DP
connectors, as it's still up to the driver to use the ELD, if any.
