Some Tegra drivers might be compiled as kernel modules, and they need the
fuse information for initialization. One example is the GK20A Nouveau
driver. It needs the GPU speedo value to calculate frequency-voltage
table. So export the tegra_sku_info.

The drm_get_edid() function performs direct I2C accesses to read EDID
blocks, assuming that the monitor DDC interface is directly connected to
the I2C bus. It can't thus be used with HDMI encoders that control the
DDC bus and expose EDID blocks through a different interface.
Refactor drm_do_get_edid() to take a block read callback function
instead of an I2C adapter, and export it for direct use by drivers.
As in the general case the DDC bus is accessible by the kernel at the
I2C level, drivers must make all reasonable efforts to expose it as an
I2C adapter and use drm_get_edid() instead of abusing this function.

DRM slave encoders require their associated struct drm_encoder instance
to be embedded in a struct drm_slave_encoder. This makes processing
encoders regardless of their types needlessly and painfully complex in
drivers that use a mix of slave encoders and custom encoders. Such a
driver will need to either create drm_slave_encoder instances that fake
their embedded encoder instance, or to turn all drm_encoder instances
into drm_slave_encoder instances.
Between the two evils, one must choose the lesser. Use drm_slave_encoder
everywhere.

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all of which have been addressed or superseded: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,

Registering the Exynos DRM subdevices platform drivers in the probe
function is causing an infinite loop. Fix this by moving it to the
exynos_drm_init() function to register the drivers on module init.
Registering drivers in the probe functions causes a deadlock in the parent
device lock. See Grant Likely explanation on the topic:
"I think the problem is that exynos_drm_init() is registering a normal
(non-OF) platform device, so the parent will be /sys/devices/platform.
It immediately gets bound against exynos_drm_platform_driver which
calls the exynos drm_platform_probe() hook. The driver core obtains
device_lock() on the device *and on the device parent*.
Inside the probe hook, additional platform_drivers get registered.
Each time one does, it tries to bind against every platform device in
the system, which includes the ones created by OF. When it attempts to
bind, it obtains device_lock() on the device *and on the device
parent*.
Before the change to move of-generated platform devices into
/sys/devices/platform, the devices had different parents. Now both
devices have /sys/devices/platform as the parent, so yes they are
going to deadlock.
The real problem is registering drivers from within a probe hook. That
is completely wrong for the above deadlock reason. __driver_attach()
will deadlock. Those registrations must be pulled out of .probe().
Registering devices in .probe() is okay because __device_attach()
doesn't try to obtain device_lock() on the parent."

This reverts commit cea24824ab432f8acabb254d6805e9aa756de6af.
Moving subdriver probe to exynos_drm_platform_probe() was making
exynos_drm_device_subdrv_probe() fail because the platform data wasn't set
yet. It only gets set in exynos_drm_load.
We need to find a smarter way to fix this issue.

The patch replaces accesses to display->ctx pointer by container_of
construct. The field is removed as well as dpi was the last user of it.

exynos_drm_display is used by internal Exynos DRM framework for
representing encoder:connector pair. As it should be mapped 1:1 to dpi
private context it seems more reasonable to embed it directly in that context.
As a result further code simplification will be possible.
Moreover it will be possible to handle multiple dpi devices in the system.

The exynos_dsi_te_irq_handler() works only dsi(DPMS) is on.
So it is enough to enable and disable TE GPIO IRQ in
exynos_dsi_enable(disable)_irq() like DSI IRQ.

The drm_helper_hpd_irq_event() does dpms control and
the panel is initialized and displayed on by it.
So the exynos_dsi_te_irq_handler() should be registered
beforehand.
