The imx-drm driver was put into staging mostly for the following reasons,
all of which have been addressed or superseded:
- convert the irq driver to use linear irq domains
- work out the device tree bindings, this lead to the common of_graph
bindings being used
- factor out common helper functions, this mostly resulted in the
component framework and drm of_graph helpers.
Before adding new fixes, and certainly before adding new features,
move it into its proper place below drivers/gpu/drm.

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.
v2: Fix #include ordering for tegra, reported by 0-day builder.
v3: Include required headers, reported by Thierry.

HDMI currently stops working after a system suspend/resume cycle. The
cause is that the mode setting states in hardware gets lost and isn't
restored across the suspend/resume cycle.
The patch adds a very basic suspend/resume support to imx-drm driver,
and calls drm_helper_resume_force_mode() in .resume hook to restore the
mode setting states, so that HDMI can continue working after a system
suspend/resume cycle.
Since the suspend/resume hook can be called with drm_device pointer
being NULL from driver data, we need a check on the pointer in the
hooks. And to avoid using a stale pointer from driver data, it also
clears driver data in .unload hook.

One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

This reverts commit 48ba813701eb14b3008edefef4a0789b328e278c.
Thanks to Chris:
"drm_file->is_master is not synomous with having drm_file->master ==
drm_file->minor->master. This is because drm_file->master is the same
for all drm_files of the same generation and so when there is a master,
every drm_file believes itself to be the master. Confusion ensues and
things go pear shaped when one file is closed and there is no master
anymore."

The drm_file->is_master field is redundant as it's equivalent to:
drm_file->master && drm_file->master == drm_file->minor->master
1) "=>"
Whenever we set drm_file->is_master, we also set:
drm_file->minor->master = drm_file->master;
Whenever we clear drm_file->is_master, we also call:
drm_master_put(&drm_file->minor->master);
which implicitly clears it to NULL.
2) "<="
minor->master cannot be set if it is non-NULL. Therefore, it stays as
is unless a file drops it.
If minor->master is NULL, it is only set by places that also adjust
drm_file->is_master.
Therefore, we can safely drop is_master and replace it by an inline helper
that matches:
drm_file->master && drm_file->master == drm_file->minor->master

In a board setup which disables LDB device node completely by changing
status to 'disabled', and only enables HDMI device, we're running into
the problem that imx-drm master never succeeds in binding, and hence
HDMI does not come up either.
&ldb {
status = "disabled";
lvds-channel@1 {
...
status = "okay";
};
};
The imx-drm-core should really skip the LVDS channels no matter what
lvds-channel's status is, if LDB device is disabled. Let's consider
such setup a misconfiguration, give a warning in there and not add the
component.

into staging-next
Russell writes:
This set of changes reorganises imx-drm's DT bindings by re-using the OF
graph parsing code which was located in drivers/media, removing the
temporary bindings.
The result is that more TODO entries are now removed. While we're not
quite done with this yet as there's a few straggling updates to imx-ldb
to come, but leaving these out is not detrimental at this point in time
- they are more an enhancement.
However, this pull has the additional complication that we're sharing
seven commits with Mauro's V4L git tree, which move the OF graph parsing
code out of drivers/media into drivers/of. Philipp's imx-drm changes
depend on these and my previously committed round of imx-drm commits.
Hence, the diffstat below is from a test merge with your tree head
(17b02809cfa7).
Mauro merged those seven commits earlier today as a git pull, so both
trees will be sharing exactly the same commit IDs.
I've given these changes a spin here on both my Hummingboard and Cubox-i4
(one is iMX6Solo, the other is iMX6Quad based), which includes Xorg using
the DRM device directly, and I find nothing wrong.
The diffstat does look a little scarey - this is because we're having to
update the ARM DT files along with this change, and obviously the
dependency on the OF graph parsing code.

between encoder and crtcs
This patch adds support to find the involved components connected to
the IPU display interface ports using the OF graph bindings documented
in Documentation/devicetree/bindings/media/video-interfaces.txt.
It makes use of the of_graph (formerly v4l2_of) parsing helpers and
thus depends on the patch that moves those out to drivers/of.
Each display interface needs to have an associated port node in the
device tree. We can associate this node with the crtc platform device
and use it to find the crtc corresponding to a given port node instead
of using a combination of parent device node and id number, as before.
Explicitly converting the void* cookie to the port device tree node
allows to get rid of the ipu_id and di_id fields. The multiplexer
setting on i.MX6 now can be obtained from the port id (reg property)
in the device tree.
The imx-drm node now needs a ports property that contains phandles
to each of the IPU display interface port nodes. From there, all
attached encoders are scanned and enabled encoders are added to a
waiting list.
The bind order makes sure that once all components are probed, crtcs
are bound before encoders, so that imx_drm_encoder_parse_of can be
called from the encoder bind callbacks.
For parsing the OF graph, temporary copies of the V4L2 OF graph
helpers are used, that can be removed again once those are available
at a generic place.

use this to get the imxdrm device, and also use it to register the CRTC

Address the following issues:
- imx_drm_encoder_get_mux_id() searches the CRTC list for the matching
CRTC, and returns the position within this list as the MUX programming
value for encoders. This is sub-optimal for two reasons:
1. It relies upon the CRTC list not changing during the lifetime of
the driver.
2. It is dependent on the initialisation order of the CRTCs.
We address (1) in this patch, leaving (2) until a better solution can
be found, as (2) requires larger changes.
- imx_drm_encoder is unused. Instead, pass the drm_encoder which is
slightly more useful; all callers pass encoder->crtc as the required
crtc, so move this inside the function.

We must not add more CRTCs than we have declared to the vblank
helpers, otherwise we overflow their arrays. Force failure if we
exceed the number of CRTCs.

imx_drm_crtc_register() doesn't clean up the CRTC upon failure, which
leaves the CRTC attached to the DRM device. Also, it does setup after
attaching the CRTC to the DRM device.
Fix this by reordering the function such that we do the setup before
drm_crtc_init(): this fixes both issues.

We must call drm_vblank_cleanup() on the error cleanup and unload paths
after we've had a successful call to drm_vblank_init(). Ensure that
the calls are in the reverse order to the initialisation order.

imx_drm_add_crtc() was kfree'ing the imx_drm_crtc structure while
leaving it on the list of CRTCs. Delete it from the list first.

commit b8d181e408af (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.
